how did sarcosuchus become extinct

Its skull alone was as big as a human adult (1.78 m, or 5 ft 10 inches). The first 'crocodile-like reptiles' (the Crocodylomorpha), which split from the bird-line of archosaurs (the group of reptiles that include dinosaurs, pterosaurs and birds) about 230 million years ago (in the Late Triassic), looked somewhat like modern crocodilians. [citation needed]. The length of Sarcosuchus was the average of the expected length of the narrow-snouted gharial and the intermediate-snouted saltwater crocodile, while the mass was the expected mass of the latter. It moved it horizontally, generating a tremendous drive force, which allowed it to reach velocities in the water sufficient to hunt for fast-moving fish. It was also given its name, a name which means “flesh crocodile” in Greek. In addition, the teeth do not interlock [citation needed], like those of mostly piscivorous crocodilians. Sarcosuchus inhabited the North Africa. 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". Sarcosuchus (meaning 'flesh crocodile' and commonly called "SuperCroc", is an extinct genus of crocodyliform and distant relative of the crocodile. However, Benton and Clark determined in 1988 that Mesosuchia was a paraphyletic group, containing the ancestor of all modern crocodiles. His estimates claim that the Sarcosuchus bite force could reach 80 kN, which is equivalent to about 8 tons of force, while the Deinosuchus could reach 10.5 tons/cm2 (23 100 lbs)! © NewDinosaurs.com, 2019. Until recently, all that was known of the genus was a few fossilized teeth and armour scutes, which were discovered in the Sahara Desert by the French paleontologist Albert-Félix de Lapparent, in the 1940s or 1950s. Deinosuchus, which is only known from skulls, had a smaller skull than Sarcosuchus [citation needed], but a broad snout, like an alligator. The climate eventually changed though and caused the Sahara to spread across the region. Vol. 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. [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. 1999. According to his research, the saltwater crocodile has a larger bite force (1.68 tons/cm2) than the commonly favored American alligator (964 kg). Sarcosuchus also had a strange depression at the end of its snout. But enough of such specific discussions considering the scientific classification – let’s leave it to the enthusiasts and head straight to the point . Sarcosuchus is a member of the family Pholidosauridae, more distantly related to today's crocodilians. You really can’t get an idea of how big this crocodile was until you have looked at Sarcosuchus pictures, especially ones showing them as compared to humans. Dinosaurs became extinct at the end of the Cretaceous period, approximately 65 million years ago. However, in 1997 and 2000, Paul Sereno discovered half a dozen new specimens, including one with about half the skeleton intact and most of the spine. How the "Terror Crocodile" Grew so Big. This suggests that, like the Nile crocodile, it may have complemented a primarily fish diet with terrestrial animals, at least upon maturity. 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). However, at the time this crocodile lived, this area was a tropical region with rivers and plenty of vegetation. The next major expedition was Paul C. Sereno's trip, in 1997 and the follow-up trip in 2000. The primary difference is that species with a long snout have larger heads in proportion to their bodies than species with relatively broad snouts. While there is a genetic component, growing that large also requires a rich diet. Sarcosuchus – SuperCroc. One of the most interesting facts about Sarcosuchus, however, wasn’t its enormous size but its eyes. This suggests that the animal probably spent most of its time with the majority of its body submerged, watching the shore for prey. Sarcosuchus could probably exert a force of 80 kN (18,000 lbf) with its jaw, making it very unlikely that prey could escape. This page presents some of the most popular thoeries. Institut de Recherches en Sciences Humaines, The Giant Crocodyliform Sarcosuchus from the Cretaceous of Africa, SuperCroc's jaws were superstrong, study shows, Sereno, team discover prehistoric giant Sarcosuchus imperator in African desert, https://fossil.fandom.com/wiki/Sarcosuchus?oldid=35445, Erickson, G.M. It is only then that you get a good idea of just how large these prehistoric crocodiles really were. The very largest Sarcosuchus is believed to have been the oldest. The huge jaw contained 132 thick teeth (Larsson said they were like "railroad spikes" [citation needed]). [citation needed] Four other species of extinct Crocodyliformes were also discovered in the same rock formation along with the Sarcosuchus, including a dwarf crocodile with a tiny, 8 cm (3 in) long skull. The jaws were relatively narrow (especially in juveniles). Sarcosuchus lived in Northern Africa, in what is now known as the Sahara Desert. 2001. As we know, the first crocodiles appeared 228 million years ago, in the Triassic Period (Mesozoic Era). Was that the true state of affairs, or was it only the pursuit of prestige and extrapolation took one step too far? It was almost twice as long as the modern saltwater crocodile and weighed approximately 8 to 10 tonnes. Want to know more information about dinosaur extinction? However, their fossils are less complete. Relatively recently (in terms of geological periods :)) this area transformed into a Sahara desert. Feel free to add the correct citations where the information is gathered from. That would have made it large enough to defend its territory from some of the theropods that may have existed at the time. The climate eventually changed though and caused the Sahara to spread across the region. The purpose of this structure remains enigmatic. 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. What is the name of agent 007? This skull would become the holotype of the species. The teeth were conical, adapted for grabbing and holding; instead of narrow, adapted for slashing (like the teeth of some land-dwelling carnivores), and more like that of true crocodilians. Deinosuchus, which was from the Late Cretaceous of what is now North America, is also a good example of a giant crocodile that is only distantly related to Sarcosuchus. Sereno and others asked various reptile researchers what their thoughts on this bulla were. A crocodilian is any member of the clade Crocodilia. Therefore, it’s quite likely that it hunted in the same way as modern crocodiles do today. Sarcosuchus is not an ancestor of modern crocodiles. We may only leave those questions pending an unequivocal answer. In the years 1997 and 2000, an American paleontologist Paul Sereno discovered several unknown specimens, including one that was preserved almost half-completely, even the spine. The holotype specimen is MNN 604. This article has been marked as a page which needs references. That said, a monster. Sarcosuchus was a prehistoric crocodile which lived approximately 112 million years ago during the Early Cretaceous Period. As a group, they are narrow-snouted fish-eaters from saltwater environments, except for the broader snouted, river-dwelling Sarcosuchus. It may have come into conflict with Suchomimus, an 11 m (36 ft) theropod dinosaur with a gharial-like snout, whose fossils were found in the same geological formation as Sarcosuchus. One 80% grown specimen was discovered with 40 rings, indicating that it had lived for 40 years. Creatures considered crocodiles, apart from the present-day animals of this superorder, traditionally include all extinct Crocodylomorpha reptiles. 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. It is pertinent to note, though, that the lobe-finned fish that shared the waters with Sarcosuchus were often in excess of 1.8 m (6 ft) long and 90 kg (200 lb) in weight. The scutes served as armor and may have helped support its great mass, but also restricted its flexibility. Osteoderm growth rings taken from an 80% grown individual (based on comparison to largest individual found) suggest that Sarcosuchus kept growing throughout its entire 50–60 year average life span (Sereno et al., 2001). Other crocodilian biologists are skeptical of the animal's "giant killing" capabilities. One hundred million years later, a large, old specimen of the saltwater crocodile, Crocodylus porosus, can weigh a ton. Sarcosuchus (meaning 'flesh crocodile' and commonly called "SuperCroc", is an extinct genus of crocodyliform and distant relative of the crocodile.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. Based on different research we outline some theories about why they became extinct. 100 million years ago, when the North Africa was a green, tropical region covered with a dense network of rivers and streams. It was 1964, however, before a skull was discovered by geologists and brought to the attention of Philippe Taquet. King of the Crocodylians: The Paleobiology of. It was first discovered during the 1950s in Aoulef, Algeria and Gara Kamboute, Tunisia by a team led by French paleontologist Albert-Félix de Lapparent. This force was calculated to be 80 kN (18,000 lbf). Called a bulla, it has been compared to the ghara seen in gharials. No skeleton was complete enough to measure directly, so the maximum length estimate was calculated by measuring the largest skull and comparing it to modern crocodiles. As no complete skeleton was found yet, the size of Sarcosuchus was estimated based on the size of present-day crocodiles. Based on the number of fossils discovered, the aquatic Sarcosuchus was probably plentiful in these warm, shallow, freshwater habitats. Sarcosuchus was not known until very recently but only from a few teeth fossils and scales which were found in the Sahara desert by a French paleontologist Albert-Félix de Lapparent in the year 1940 or 1950. [citation needed]. Unlike the ghara, though, the bulla is present in all Sarcosuchus skulls that have been found so far. 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. Unsurprisingly, it was not bothered by their loss, and unlike us, it did not have to make dental appointments, brr. While still comparatively narrower than the snout of a Nile crocodile, the snout is still much wider than the snouts of crocodilians like the gharial.
