how did sarcosuchus become extinct

This form of growth rate calculation has been somewhat controversial. Sarcosuchus is a member of the family Pholidosauridae, more distantly related to today's crocodilians. Every other gigantic crocodylomorphs is known merely by a few incomplete skull fossils, which stresses the question which one was indeed of the greatest size. The Sarcosuchus belongs to the Crocodylomorpha superorder, as well as the present-day crocodiles, yet it is not their direct ancestor. However, as a matter of fact, it was relatively narrow, contrary to the prehistoric alligator – Deinosuchus. King of the Crocodylians: The Paleobiology of. Dinosaurs became extinct at the end of the Cretaceous period, approximately 65 million years ago. Sarcosuchus was approximately 40 feet long – or about the size of a whale shark – and weighed about 15 tons, which is about 7 tons heavier than an elephant! 110 million years ago, in the Early Cretaceous, the Sahara was still a great tropical plain, dotted with lakes and crossed by rivers and streams that were lined with vegetation. This may in part be due to body design (the armoured plates of the back can provide structural support to a massive body [citation needed]) and in part due to environment (water can buoy up their massive bodies) (See also: Cope's law). As well as the present-day crocodiles and snakes (see: Anaconda, Python), Sarcosuchus grew in a constant manner throughout its whole life (this was established through comparison of fossil bone sections found by paleontologists). According to Sereno [citation needed], "because the ancient animal was so large, it could easily handle huge dinosaurs, including the massive long-necked, small-headed sauropods that were common in that African region". In addition, the teeth do not interlock [citation needed], like those of mostly piscivorous crocodilians. Sarcosuchus lived in Northern Africa, in what is now known as the Sahara Desert. This page presents some of the most popular thoeries. One of the most interesting facts about Sarcosuchus, however, wasn’t its enormous size but its eyes. Sarcosuchus used to be over 10 metres long, and it is believed that they used to reach 12 metres. Sarcosuchus imperator skull in Expominer 2007, Barcelona. Keep in mind that there is … Sarcosuchus could weigh as much as eight tonnes. But enough of such specific discussions considering the scientific classification – let’s leave it to the enthusiasts and head straight to the point . [2], Mounted Sarcosuchus skeleton replica at the Children's Museum of Indianapolis showing osteoderms, It had a row of bony plates or osteoderms, running down its back, the largest of which were 1 m (3 ft) long. However, Benton and Clark determined in 1988 that Mesosuchia was a paraphyletic group, containing the ancestor of all modern crocodiles. According to his research, the saltwater crocodile has a larger bite force (1.68 tons/cm2) than the commonly favored American alligator (964 kg). Crocodilia includes all modern forms (such as crocodiles proper, alligators etc) and their immediate prehistoric relatives. Giant crocodiles seem to be a good example of convergence because, according to Schwimmer [citation needed], "the idea of really big crocs is a repeat theme in evolution". He shipped it to Paris, where it was examined by France de Broin. The climate eventually changed though and caused the Sahara to spread across the region. By comparing the force exerted by more than 60 animals, they were able to determine that the force exerted was proportional to the size of the animal, which allowed an estimate of the biting power of the Sarcosuchus. Much can be said about the everyday habits of an animal by the analysis of shape and structure of its eyes. ; Gado, B. [citation needed]. A simplified evolutionary tree (Sereno, 1998): Teeth and osteoderms found in Brazil belong to a close relative of Sarcosuchus. You can also take a look at the articles talk page to see if anything is mentioned there which can give some tips. As we know, the first crocodiles appeared 228 million years ago, in the Triassic Period (Mesozoic Era). Some think it was merely an enhanced olfactory organ that allowed it to smell things from really far away. The Sarcosuchus, or alternatively, SuperCroc, apart from its great general size, also had a massive skull and jaws. and Brochu, C.A. It was also given its name, a name which means “flesh crocodile” in Greek. It took about a year to prepare the Sarcosuchus remains. You can read more about it, The Marine Reptiles of The Late Cretaceous, Was 15 feet longer than a saltwater crocodile. Sarcosuchus – commonly referred to as SuperCroc, while really its name literally means… an overweight crocodile. This article has been marked as a page which needs references. Sarcosuchus inhabited the North Africa. Feel free to add the correct citations where the information is gathered from. This force was calculated to be 80 kN (18,000 lbf). That said, a monster. A crocodilian is any member of the clade Crocodilia. Unlike modern true crocodiles, which are very similar in size and shape to one another and tend to live in different areas; Sarcosuchus was just one of many Crocodyliformes, of different sizes and shapes, all living in the same area. 100 million years ago, when the North Africa was a green, tropical region covered with a dense network of rivers and streams. When fully mature, Sarcosuchus is believed to have been as long as a city bus (11.2–12.2 meters or 37–40 ft) and weighed up to 8 tonnes (8.75 tons). By the way – its teeth actually were not so sharp. They had long legs, long bodies covered with armour. The upper jaw overlapped the lower jaw, creating an overbite. It was larger because it kept growing, reaching full adulthood in 35 years, instead of 10. Modern crocodiles grow at a rapid rate, reaching their adult size in about a decade, then growing more slowly afterwards. [citation needed] This raises the possibility of those adaptations, which seem to indicate large or moderate-sized terrestrial prey, may instead have been adaptations for dealing with exceptionally large fish (many species of which possessed a layer of osteoderms, for protection). Since they retain growth rings, like those found in trees (most other bones 'suffer' remodeling with age, which destroys former growth rings), it is theoretically possible to count the age of the individual that the bones belonged to. We may only leave those questions pending an unequivocal answer. It dates from the early Cretaceous Period of what is now Africa and is one of the largest giant crocodile-like reptiles that ever lived. Nevertheless the dispute remains unsettled. On the other hand, based on the structure of the snout, the closest relative of Sarcosuchus is the pholidosauridTerminonaris, with Dyrosaurus and Pholidosaurus as slightly more distant relatives. Another interesting fact is that Sarcosuchus had a bulbous depression at the end of its snout and paleontologists aren’t really sure what its purpose was. Sarcosuchus (meaning 'flesh crocodile' and commonly called "SuperCroc", is an extinct genus of crocodyliform and distant relative of the crocodile. The holotype specimen is MNN 604. My name is ....

Others (Schwimmer, 2002) have criticised this form of growth measurement, as annular rings are harder to determine in a creature that lives in an environment that is without extreme seasonality (such as the Mesozoic). As we know, the first crocodiles appeared 228 million years ago, in the Triassic Period (Mesozoic Era). Sarcosuchus could probably exert a force of 80 kN (18,000 lbf) with its jaw, making it very unlikely that prey could escape. However, at the time this crocodile lived, this area was a tropical region with rivers and plenty of vegetation. Most likely it spent most of the time submerged in the river waters, seeking potential prey. The largest alligator they tested was able to exert a force of 9.45 kN (2,125 lbf). This means that the skull of the Deinosuchus is probably a smaller portion of its total body length than the skull of the long-snouted Sarcosuchus, so its total size may be as large, or even larger. This suggests it was not a sexually selected character (only the male gharial has a ghara). [citation needed]. How Did Dinosaurs Become Extinct? Based on the number of fossils discovered, the aquatic Sarcosuchus was probably plentiful in these warm, shallow, freshwater habitats. Take your favorite fandoms with you and never miss a beat. Vol. Fossil Wiki is a FANDOM Lifestyle Community. As the overhanging jaw and stout teeth are designed for grabbing and crushing, its primary prey may have been large animals and smaller dinosaurs, which it ambushed, dragged into the water, crushed, drowned and then tore apart. However some biologists claim that its capability of killing larger prey are overestimated, as it could be compared to a bigger version of the present-day gavial as well as the Rhamphosuchus. We ask "How did dinosaurs become extinct?" Sarcosuchus – SuperCroc. Sarcosuchus lived in Northern Africa, in what is now known as the Sahara Desert. This article has been marked as a page which needs references. Sereno also measured living crocodilians in India and Costa Rica and used that data in his analysis. As part of a National Geographic Special, Greg Erickson of Florida State University, Kent Vliet of the University of Florida and Kristopher Lapping of Northern Arizona University provoked American alligators, at the St. Augustine Alligator Farm and Zoological Park in Florida, into biting a bar studded with piezoelectric sensors.
