bite force of crocodile

bite force of crocodile

American crocodiles breed in late fall or early winter during which males emit very low-frequency bellows to attract for mating. The bite force of American crocodile is recorded is about 3000 psi. The bite force can increase or decrease as the size of the crocodiles varies. [16] This was later corroborated when it was noted that most known specimens of D. rugosus usually had skulls of about 1 meter (3.3 ft) with estimated total lengths of 8 meters (26 ft) and weights of 2.3 metric tons (2.5 short tons). [11][12] The secondary palate and procoelous vertebrae are advanced features also found in modern eusuchian crocodilians. Irmis RB, Hutchison JH, Sertich JJW, Titus AL. With a bite of about 3,700 PSI, a crocodile is among the animals with the strongest bites in the world. It hunted in the water where the giant theropods could not go. The name translates as "terrible crocodile" and is derived from the Greek deinos (δεινός), "terrible", and soukhos (σοῦχος), "crocodile". saltwater crocodile bite force: 7500 psi [7][107] Crocodiles are occasionally successful in grabbing passerines such as weaver birds, including the abundant red-billed quelea (Quelea quelea), and swallows, having been observed to … According to Erickson, a full-grown Deinosuchus "must have seen several generations of dinosaurs come and go". [4][15] These deeply pitted osteoderms have been used to suggest that, despite its bulk, Deinosuchus could probably have walked on land much like modern-day crocodiles. Deinosuchus reached its largest size in its western habitat, but the eastern populations were far more abundant. Average of 1766kg / cm2. Bite Force: 3700 to 7700 psi Average Size: 17 feet (male) Average Weight: 1,000 pounds Average Life Span: 70 years Found in: B rackish and fresh water in e astern India, southeast Asia and northern Australia The saltwater crocodile, the largest living crocodile on earth is the most likely animal to eat humans. The crocodiles get the force from the jaw muscles and exert a huge pressure to lock their food in their jaws. https://nedhardy.com/2020/04/18/which-animal-has-the-strongest-bite The environment conditions also affect the age of the animals that are living in the wild habitat. Their large, powerful jaws make their snouts deadly traps from which escape is nearly impossible for prey. [3] The skull of Deinosuchus itself was of a unique shape not seen in any other living or extinct crocodilians; the skull was broad, but inflated at the front around the nares. Most were quite fragmentary, but they expanded knowledge of the giant predator's geographic range. By contrast, you might tear into a steak with 150 to 200 psi (890 newtons). The bite force of American crocodile is recorded is about 3000 psi. Two holes in the premaxilla in front of the nares are present in this genus and are unique autapomorphies not seen in other crocodilians, but nothing is known at present regarding their function. [38], The species pertaining to Deinosuchus since the resurrection of the generic name in 1979 have been traditionally recognized as D. rugosus from Appalachia and the larger D. hatcheri/riograndensis from Laramidia, characterized by differences of the shape of their osteoderms and teeth. 1 Saltwater Crocodile. Females reach their reproduction maturity at a length of about 2.8 m. The American crocodiles are not dangerous for the humans if you not provoked. [19] All known specimens of Deinosuchus were found in rocks dated to the Campanian stage of the Late Cretaceous period. It would be easier to lift a car of your legs than to open the jaws of saltwater crocodiles that has a grip on you. It is one the four extant species from the Americas which found across the world. [34] Later discoveries showed that Polyptychodon was actually a pliosaur, a type of marine reptile. Opinion remains divided as to whether these two populations represent separate species. [15] Together, the osteoderms and connective tissue would have served as load-bearing reinforcement to support the massive body of Deinosuchus out of water. [19] Deinosuchus has been described as a "conspicuous" component of a purportedly distinct biome occupying the southern half of Late Cretaceous North America. At the Top of the Grand Staircase: The Late Cretaceous of Southern Utah. The extraordinary bite of crocodilians is explained by … [4] The tooth count for each dentary (tooth-bearing bone in the lower jaw) was at least 22. Spectacular Show of Crocodile Bite Strength Caught on Video April 16, 2018 Elvis the crocodile shows the incredible strength of his jaws in this eye-popping demonstration in Australia. rugosus. Crocodyliforms from the Late Cretaceous of Grand Staircase-Escalante National Monument and vicinity, southern Utah, U.S.A. [3] All the teeth were very thick and robust; those close to the rear of the jaws were short, rounded, and blunt. One study indicated Deinosuchus may have lived for up to 50 years, growing at a rate similar to that of modern crocodilians, but maintaining this growth over a much longer time. Apparently, the force of a crocodile's bite scales with size. [10] The vertebrae were articulated in a procoelous manner, meaning they had a concave hollow on the front end and a convex bulge on the rear; these would have fit together to produce a ball and socket joint. [17] This is only slightly lower than previous estimates for the species. In: Titus AL, Loewen MA, eds. Certain bite tests in laboratory settings conducted by experts have confirmed the saltwater crocodile as the ultimate chomper of the wild; the reptile can shut its … Deinosuchus comes from the Greek δεινός/deinos, meaning "terrible", and σοῦχος/suchos, meaning "crocodile". When these specimens were examined, it became clear that they belonged to a large crocodilian and not a dinosaur; upon learning this, Hatcher "immediately lost interest" in the material. [15], Numerous additional specimens of Deinosuchus were discovered over the next several decades. Deinosuchus fossils have been described from 10 U.S. states, including Texas, Montana, and many along the East Coast. The first remains were discovered in North Carolina (United States) in the 1850s; the genus was named and described in 1909. The bite force generated by crocodiles is quite significant, and is comparable to the bite force produced by historic predators, such as the T. rex. Pictured above, this large powerful breed is used in Turkey to … They are capable of unleashing a devastating bite force of 16458.42 Newton per square inch (3700 psi) which is over 12 times more than humans (around 1300 Newton per square inch or 292.25 psi). [15][36] Better cranial material was also found; by 2002, David R. Schwimmer was able to create a composite computer reconstruction of 90% of the skull. [8] It has been argued that even the largest and strongest theropod dinosaurs, such as Tyrannosaurus, probably had bite forces inferior to that of Deinosuchus. The most powerful bite recorded from a living animal belongs to the saltwater crocodile For the largest sharks, the maximum bite force prediction was … American Crocodiles are mainly creatures of the salt water. [9], Deinosuchus had a secondary bony palate, which would have permitted it to breathe through its nostrils while the rest of the head remained submerged underwater. [25], In 1954, Edwin H. Colbert and Roland T. Bird speculated that Deinosuchus "may very well have hunted and devoured some of the dinosaurs with which it was contemporaneous". [31], Schwimmer and G. Dent Williams proposed in 1996 that Deinosuchus may have preyed on marine turtles. The average length varies between 4.1 to 4.8 m while females are smaller. The “winners”—saltwater crocodiles—slammed their jaws shut with 3,700 pounds per square inch (psi), or 16,460 newtons, of bite force. After the adult Purussaurus, the next strongest bite comes from the modern saltwater crocodile, Crocodylus porosus, which has a bite force of 1.6 tons. 2013. The American crocodile can extremely found in the cold temperatures and easily live in the tropical waters. Deinosuchus (/ˌdaɪnəˈsjuːkəs/) is an extinct genus of crocodilian related to the modern alligator that lived 82 to 73 million years ago (Ma), during the late Cretaceous period. [18] This classification was bolstered in 2005 by the discovery of a well-preserved Deinosuchus brain case from the Blufftown Formation of Alabama, which shows some features reminiscent of those in the modern American alligator,[37] Deinosuchus, however, was not a direct ancestor of modern alligators. Even the hyena with its notorious jaws couldn’t muster more than 1100 pounds. The adult American crocodile has. [4], In 1858, geologist Ebenezer Emmons described two large fossil teeth found in Bladen County, North Carolina. Saltwater Crocodile (4,000 PSI) "Don't worry, being eaten by a crocodile is just like going to sleep—in … However, the muscles responsible for opening the mouth are exceptionally weak, allowing a person to easily hold them shut, and even larger crocodiles can be brought under control by the use of duct tape to bind the jaws together. Saltwater crocodiles not only have the most powerful bites in the crocodile world, they're also the biggest of them all. North Carolina Museum of Natural Sciences, "A systematic review of the giant alligatoroid, "Insights into the Ecology and Evolutionary Success of Crocodilians Revealed through Bite-Force and Tooth-Pressure Experimentation", "The ontogeny of bite-force performance in American alligator (, "A gigantic crocodile from the Upper Cretaceous beds of Texas", 10.1671/0272-4634(2005)025[0354:FDABSO]2.0.CO;2, "First report of the hyper-giant Cretaceous crocodylian, "Late Campanian Southern Dinosaurs, Aguja Formation, Big Bend, Texas", 10.1666/0022-3360(2001)075<0208:LCSDAF>2.0.CO;2, 10.1669/0883-1351(2003)018<0080:BR>2.0.CO;2, "Anatomy of the skull and braincase of a new, https://en.wikipedia.org/w/index.php?title=Deinosuchus&oldid=991555071, Late Cretaceous crocodylomorphs of North America, Late Cretaceous reptiles of North America, All Wikipedia articles written in American English, Creative Commons Attribution-ShareAlike License, This page was last edited on 30 November 2020, at 17:49. In comparison, American alligators (Alligator mississippiensis) have a bite force of 2,980 psi -- still less than saltwater crocs. [22] Deinosuchus fossils are most abundant in the Gulf Coastal Plain region of Georgia, near the Alabama border. The population of the species is considered under threatened. American Crocodile has V-shaped snout as compared to other large crocodiles which usually have a slightly broad snout. The bite force can increase or decrease as the size of the crocodiles varies. [34] Although not initially recognized as such, these teeth were probably the first Deinosuchus remains to be scientifically described. By contrast, you … Nile Crocodile Characteristics These osteoderms were initially attributed to the ankylosaurid dinosaur Euoplocephalus. In the United States, the American alligator has one of the most powerful bites among all crocodile species in the country. Crocodiles grow up to be 6 feet long and weigh more than a ton.With five thousand tons of bite force. According to Google, the saltwater crocodile may have the strongest bite ever measured, but that might be because it's been impossible to measure the killer whale's bite force with accuracy. It is believed to be the bite of a Nile crocodile is as high as … However, other crocodyliforms such as Purussaurus, Rhamphosuchus, and Sarcosuchus may have equaled or exceeded it in size. It mostly inhabits in the water such as river mouths, salt lakes, mangrove swamps, freshwater and sometimes found in the sea. "[29] Deinosuchus is generally thought to have employed hunting tactics similar to those of modern crocodilians, ambushing dinosaurs and other terrestrial animals at the water's edge and then submerging them until they drowned. [38] Crocodilian eggs are little brittle but softer than bird eggs. [5], A 1999 study by Gregory M. Erickson and Christopher A. Brochu suggested the growth rate of Deinosuchus was comparable to that of modern crocodilians, but was maintained over a far longer time. It may have also fed upon sea turtles, fish, and other aquatic and terrestrial prey. Saltwater crocodiles are responsible for several human deaths and water bites. [4] The bigger, but less common, Deinosuchus that lived in Texas and Montana might have been more specialized hunters, capturing and eating large dinosaurs. Based on captive orca incidents it's estimated that their … Scientists believe the most powerful bite force ever belonged to now-extinct giant crocodiles, which measured 35 to 40 feet long and may have had a bite force of up to 18,000 pounds. Bite force in humans usually tops out at about 200 psi. [4] Schwimmer noted no theropod dinosaurs in Deinosuchus's eastern range approached its size, indicating the massive crocodilian could have been the region's apex predator. Some crocodiles become the food of predators in the young age. [3] This proposal was endorsed by Lucas et al. Saltwater crocodile by Rob Gandola #JunkOff. Since a majority of fatal attacks are believed to be predatory in nature, the Nile crocodile can be considered the most prolific predator of humans among wild animals. [18], Deinosuchus was present on both sides of the Western Interior Seaway. Weighing in at up to a ton, the Nile crocodile is the top predator in Africa's rivers. The "winners"— saltwater crocodiles —slammed their jaws shut with 3,700 pounds per square inch (psi), or 16,460 newtons, of bite force. [24] Although some specimens have also been found in marine deposits, it is not clear whether Deinosuchus ventured out into the ocean (like modern-day saltwater crocodiles); these remains might have been displaced after the animals died. [20] David Schwimmer has said Deinosuchus fossils have been found in South Carolina and Delaware as well, but none of them from those two states have been formally described. The American Crocodiles are one of the larger species. Deinosuchus has often been described as the largest crocodyliform of all time. American Crocodile all information is available here like scientific name, size, weight, total population, bite force, characteristics, diet, facts, habitat, lifespan, and reproduction. The average length of the males is about 4.1 m long while females are smaller ranges between 3.8 m in length. The adult American crocodile takes the birds, mammals, turtles, snails, crabs, frogs, and sometimes carrion as well in their diet. However, the muscles of the jaws are strong to close and weak for the opening. As noted by Chris Brochu, the osteoderms are distinctive enough that even "bone granola" can adequately confirm the presence of Deinosuchus. Stanton. Deinosuchus had an alligator-like, broad snout, with a slightly bulbous tip. The young hatch the eggs after 75-80 days in the proper temperature. Though the Nile crocodile can be seen among the pictures of animals that use their tails for many purposes, it also has a painful bite.And this is why many wild animals fear these creatures. According to his research, the saltwater crocodile has a larger bite force (1.68 tons/cm 2) than the commonly favored American alligator (964 kg). These specimens were described by Edwin H. Colbert and Roland T. Bird in 1954, under the name Phobosuchus riograndensis. The crocodiles get the force from the jaw muscles and exert a huge pressure to lock their food in their jaws. [32] Deinosuchus would probably have used the robust, flat teeth near the back of its jaws to crush the turtle shells. In Trinity beach, crocodile attacks are a very common sighting. [8] The bite force of Deinosuchus has been estimated to be 18,000 N (1,835 kgf; 4,047 lbf)[2] to 102,803 N (10,483 kgf; 23,111 lbf). Males can maximum reach lengths of 6.1 m as per record. Despite its inaccuracies, the reconstructed skull became the best-known specimen of Deinosuchus, and brought public attention to this giant crocodilian for the first time. Humans have frail jaws that can tear into a piece of meat with just 150 pounds. You can gain more knowledge about Crocodile Species from this site. According to the formula that 4.6 saltwater crocodile that had a bite force of 3800 would have a … The maximum documented size of American crocodile is 6.1 m. The male maximum can weight up to 907 kg while on average, they reach up to 400 kg. the large animals as most of the large crocodiles do. Saltwater crocodile. [15], In 1903, at Willow Creek, Montana, several fossil osteoderms were discovered "lying upon the surface of the soil" by John Bell Hatcher and T.W. Utterback, yielded further fossils, including additional osteoderms, as well as vertebrae, ribs, and a pubis. Modern saltwater crocodiles (Crocodylus porosus) have the strongest recorded bite of any living animal, with a maximum force of 16,414 N (1,673.8 kgf; 3,690 lbf) for a 4.59 meters (15.1 ft) specimen . Kangal – 743 psi. Jaw shape demonstrates surprisingly little correlation to bite force and pressures. [5] When the mouth was closed, only the fourth tooth of the lower jaw would have been visible. With one of the most powerful jaws on earth, the crocodile’s bite force measured 3,700 pounds per square inch. [10][13], The osteoderms (scutes) covering the back of Deinosuchus were unusually large, heavy, and deeply pitted; some were of a roughly hemispherical shape. But now the count reaches the thousands in various regions. I especially like that just by obtaining a crocodile's bite force you could calculate its weight. The age of the American Crocodile is estimated about 30 – 70 years. The juveniles have dark cross banding on their back and tail. The American Crocodile is the species of the crocodilian found in the Neotropics which is one the eight biographic realms constituting the earth’s land surface. [21] There is also a report describing a possible Deinosuchus scute from Colorado. It had large, robust teeth built for crushing, and its back was covered with thick hemispherical osteoderms. [19] A Deinosuchus osteoderm from the San Carlos Formation was also reported in 2006, so the giant crocodilian's range may have included parts of northern Mexico.

Nevertheless, the gharial's extremely slender jaws are relatively weak and built more for quick jaw closure. Colbert and Bird stated this was a "conservative" reconstruction, since an even greater length could have been obtained if a long-skulled modern species, such as the saltwater crocodile had been used as the template. [19] Specimens have been described from 10 U.S. states: Utah, Montana, Wyoming, New Mexico, New Jersey, Georgia, Alabama, Mississippi, Texas, and North Carolina. However, estimates of how large it really was have varied considerably over the years. They appear to have been adapted for crushing, rather than piercing. Although Deinosuchus was far larger than any modern crocodile or alligator, with the largest adults measuring 12 meters (39 ft) in total length, its overall appearance was fairly similar to its smaller relatives. Though bite forces for all animals are approximate estimates since this calculation must necessarily be based on a number of different factors particular to each individual animal. [3] Each maxilla (the main tooth-bearing bone in the upper jaw) contained 21 or 22 teeth. In the 1970s, the population of the American crocodiles is about only a few hundred. Holland assigned these specimens to a new genus and species, Deinosuchus hatcheri, in 1909. Fossils have also been found in northern Mexico. [4][10], The large size of Deinosuchus has generally been recognized despite the fragmentary nature of the fossils assigned to it. [11] Colbert restated this hypothesis more confidently in 1961: "Certainly this crocodile must have been a predator of dinosaurs; otherwise why would it have been so overwhelmingly gigantic? Deinosuchus was probably capable of killing and eating large dinosaurs. The bite force exerted by an adult Nile crocodile has been shown by Brady Barr to measure 22 kN (5,000 lbf). [11] However, this reconstruction is currently considered to be inaccurate. It is the only species other than the saltwater crocodile to commonly live and thrive in the salt water. The appearance is very similar to the large lizard. Excavation at the site, carried out by W.H. gambassa.com. Scroll this page down and get the details. A person by hold their jaws shut down and even larger crocodiles can bring under control by binding by their jaws together. "[27][28] David R. Schwimmer proposed in 2002 that several hadrosaurid tail vertebrae found near Big Bend National Park show evidence of Deinosuchus tooth marks, strengthening the hypothesis that Deinosuchus fed on dinosaurs in at least some instances. Another large tooth that likely came from Deinosuchus, discovered in neighboring Sampson County, was named Polydectes biturgidus by Edward Drinker Cope in 1869. [2] Each premaxilla contained four teeth, with the pair nearest to the tip of the snout being significantly smaller than the other two. A reasonably well-preserved skull specimen discovered in Texas indicated the animal's head measured about 1.31 meters (4.3 ft), and its body length was estimated at 9.8 meters (32 ft). [4] Using more complete remains, it was estimated in 1999 that the size attained by specimens of Deinosuchus varied from 8 to 10 meters (26 to 33 ft) with weights from 2.5 to 5 metric tons (2.8 to 5.5 short tons). Additional fragments were discovered in the 1940s and were later incorporated into an influential, though inaccurate, skull reconstruction at the American Museum of Natural History. If the ring cycle were biannual rather than annual, this might indicate Deinosuchus grew faster than modern crocodilians, and had a similar maximum lifespan. [15][35] The genus name Phobosuchus, which was initially created by Baron Franz Nopcsa in 1924, has since been discarded because it contained a variety of different crocodilian species that turned out to not be closely related to each other. Bite forces can now be predicted in fossil crocodilians using the regression equations generated in this research. The oldest examples of this genus lived approximately 82 Ma, and the youngest lived around 73 Ma. Don't crocodiles with large, bulky jaws tend to have a heavier mass anyway? [23], The distribution of Deinosuchus specimens indicates these giant crocodilians may have preferred estuarine environments. They would have consumed marine turtles, large fish, and smaller dinosaurs. The crocs could grow to 43ft long and weigh 8.5 tons — and the team calculated its bite force was equal to 6.5 tons. The team tested crocs around 17 feet in length, but the species is known to reach sizes of 20 feet or more, translating to an estimated bite force of 7,700 psi, almost twice the power of recorded croc measurements. American crocodiles are apex predators and any terrestrial or aquatic animal, they encounter in freshwater, coastal saltwater, riparian is the primary prey for their diet. This was a completely different growth strategy than that of large dinosaurs, which reached adult size much more quickly and had shorter lifespans. (2006),[39] but was criticized by other authors,[21][24][29] and an SVP 2010 abstract Schwimmer reported new fossils of specimens from both sides of the interior seaway that indicated that the differences between the two morphs were not just size related, teeth from large eastern specimens retained the common characteristics of other specimens of the region and osteoderms from small specimens of the western morph were no different from those of large ones, supporting the specific separation of the two morphs, D. rugosus and D. [4], A particularly large mandibular fragment from a D. riograndensis specimen was estimated to have come from an individual with a skull length of 147.5 centimeters (4.84 ft). [15] The teeth described by Emmons were thick, slightly curved, and covered with vertically grooved enamel; he assigned them a new species name, P. [5][32], Schwimmer concluded in 2002 that the feeding patterns of Deinosuchus most likely varied by geographic location; the smaller Deinosuchus specimens of eastern North America would have been opportunistic feeders in an ecological niche similar to that of the modern American alligator. However, the largest fragmentary remains of D. riograndensis were 1.5 times the size of those of the average D. rugosus and it was determined that the largest individuals of this species may have been up to 12 meters (39 ft) in length and perhaps weighed as much as 8.5 metric tons (9.4 short tons). The bite force of a German Shepherd is estimated to be 238 PSI (pounds per square inch). Nile Crocodile – Bite Force : 5000 psi. According to Schwimmer, the growth ring patterns observed could have been affected by a variety of factors, including "migrations of their prey, wet-dry seasonal climate variations, or oceanic circulation and nutrient cycles".
