hatcheri/riograndensis. 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. 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. [11], Later, in 1964, the research team of the French CEA discovered an almost complete skull in region of Gadoufaoua, in the north of Niger, said skull was shipped to Paris for study and became the holotype of the then new genus and species Sarcosuchus imperator in 1966. [11], In 1977, a new species of Sarcosuchus was recognised, S. hartti, from remains found in the late 19th century in late Hauterivian pebbly conglomerates and green shales belonging to the Ilhas Group in the Recôncavo Basin of north-eastern Brazil. [2][11][22] S. imperator shared the waters with the holostean fish Lepidotus and the coelacanth Mawsonia. [2] Approximately 40 lines of arrested growth (LAG) were counted in these thin sections, suggesting that S. imperator took 50 to 60 years to reach adult size. Illustration by Raul D. Martin, National Geographic Stock. They have flat teeth to crush hard vegetation. The name means \"terrible crocodile\" in Greek because deinos (δεινός), \"terrible\", and soukhos (σοῦχος), \"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. The name translates as "terrible crocodile" and is derived from the Greek deinos (δεινός), "terrible", and soukhos (σοῦχος), "crocodile".

Later discoveries showed that Polyptychodon was actually a pliosaur, a type of marine reptile. In 1957, in the region now known as the Elrhaz Formation in the north of Niger several isolated teeth of great size were found by H. Faure. Deinosuchus has often been described as the largest crocodyliform of all time. [19] All known specimens of Deinosuchus were found in rocks dated to the Campanian stage of the Late Cretaceous period. [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. (2011). The latest in a long line of giant prehistoric "crocs," including SuperCroc (aka Sarcosuchus) and BoarCroc (aka Kaprosuchus), the ShieldCroc, also known as Aegisuchus, was a giant, river-dwelling crocodile of middle … The fight to be the biggest crocodile out there was probably very tough in the prehistoric times. Ancient 'terror crocodile' had teeth the size of bananas - CNET [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). 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. [3] The dinosaur fauna was represented by the iguanodontian Lurdusaurus, which was the most common dinosaur in the region, and its relative Ouranosaurus; there were also two sauropods, Nigersaurus and a currently unnamed sauropod while the theropod fauna included the spinosaurid Suchomimus, the carcharodontosaurid Eocarcharia and the abelisaurid Kryptops. It was one of the largest crocodile-line reptiles, reaching an average estimate of 9 m (30 ft) and 3.5 metric tons (3.9 short tons), but estimated to grow up to 9.5 m (31 ft) in body length and weigh up to 4.3 metric tons (4.7 short tons). The small reptile grows gigantic, escapes the city sewers, and goes on a rampage. [22][23], Meanwhile, S. hartti was found in the Recôncavo Basin of Brazil, specifically in the Ilhas Formation of the Bahia series, it was a shallow lacustrine environment dating from the late Aptian, similar in age to the habitat of S. imperator, with similar aquatic fauna, including Lepidotus and two species of Mawsonia. In February, a "bonecrushing" 7-foot long crocodile –­ nicknamed the "T. Rex of its time" –­ that walked on all fours but but used its hind legs to run … Sarcosuchus was a giant relative of crocodiles, with fully grown individuals estimated to have reached up to 9 to 9.5 m (29.5 to 31.2 ft) in total length and 3.5 to 4.3 metric tons (3.9 to 4.7 short tons) in weight. The genus name comes from the Greek σάρξ (sarx) meaning flesh and σοῦχος (souchus) meaning crocodile. These specimens were described by Edwin H. Colbert and Roland T. Bird in 1954, under the name Phobosuchus riograndensis. [11] However, this reconstruction is currently considered to be inaccurate. [1], Sarcosuchus is commonly classified as part of the clade Pholidosauridae,[2][11][12] a group of crocodile-like reptiles (Crocodyliformes) related but outside Crocodylia (the clade containing living crocodiles, alligators and gharials). In 1964, an almost complete skull was found in Niger by the French CEA, but it was not until 1997 and 2000 that most of its anatomy became known to science, when an expedition led by the American paleontologist Paul Sereno discovered six new specimens, including one with about half the skeleton intact and most of the spine. There were 35 teeth in each side of the upper jaw, while in the lower jaw there were 31 teeth in each side.

[19] Specimens have been described from 10 U.S. states: Utah, Montana, Wyoming, New Mexico, New Jersey, Georgia, Alabama, Mississippi, Texas, and North Carolina. In: Titus AL, Loewen MA, eds. The mugger crocodile (Crocodylus palustris = "crocodile of the marsh"), also called the Indian, Indus, Persian, Sindhu, marsh crocodile or simply mugger, is found throughout the Indian subcontinent and the surrounding countries, like Pakistan where the Indus crocodile is the national reptile of Pakistan. The tracks ― which the authors name Batrachopus grandis ― belong to a new species of crocodylomorph, which are ancestors to modern … Pixar Wiki. [15] The teeth described by Emmons were thick, slightly curved, and covered with vertically grooved enamel; he assigned them a new species name, P. [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". Bloomington: Indiana University Press, 424–444. [12] [3] All the teeth were very thick and robust; those close to the rear of the jaws were short, rounded, and blunt. Deinosuchus comes from the Greek δεινός/deinos, meaning "terrible", and σοῦχος/suchos, meaning "crocodile". The upper jaw was also noticeably longer than the lower one leaving a gap between them when the jaws were shut, creating an overbite. 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.
