Species: Freshwater Crocodile (Crocodylus johnsoni) New Delhi: Scientists, using advanced nuclear imaging techniques, have confirmed that a 93-million-year-old crocodile, whose fossil was found in Australia, devoured a juvenile dinosaur. Have some feedback for us? Given its large head and leg-like rear flippers, it seems unlikely that the ocean-dwelling crocodile Dakosaurus was a particularly fast swimmer, though it was clearly speedy enough to prey on its fellow marine reptiles. Like other plant-eating archosaurs, it was probably hunted by the carnivorous reptiles of the Triassic period (both its fellow archosaurs and the earliest dinosaurs that evolved from them) and needed a reliable means to keep these predators at bay. For example, if a crocodile dies in a dry environment, its body can become mummified. They can be found in sedimentary rock, which forms when layers of sand, silt, and clay settle on top of one another. Age: 117 years old "This fossil is unique in its anatomy and key piece to understand the early stages of crocodiles, as the oldest of the group we call the . Clearly, Smilosuchus was the apex predator of its North American ecosystem, likely preying on smaller, plant-eating pelycosaurs and therapsids. Although it's technically classified as a phytosaur rather than a prehistoric crocodile, Rutiodon cut a distinctive crocodilian profile, with its long, low-slung body, sprawling legs, and narrow, pointed snout. It's not a direct ancestor of dinosaurs, the authors say, but it's the oldest known dinosaur cousin. In celebration of his 112th birthday in 2015, Cassius was met with fervent celebration and was gifted a chicken birthday cake to commemorate the special occasion. The world's oldest crocodilian eggs laid 152 million years ago have been discovered in cliffs in Portugal. Long story short, Gracilisuchus provides further evidence that the big, slow, plodding crocodiles of the present day are the descendants of fast, two-legged reptiles of the Triassic period..

Our website offers a wealth of information on all things reptilian, from care and husbandry tips to in-depth articles on the natural history of these amazing creatures. These animals arose approximately 200 million years ago and have since outlived dinosaurs by approximately 66 million years. Not literally a cross between a duck and a crocodile, Anatosuchus, the DuckCroc, was an unusually small (only about two feet from head to tail) ancestral crocodile equipped with a broad, flat snout--similar to those sported by the contemporary hadrosaurs (duck-billed dinosaurs) of its African habitat. A (further) corrupted form cocodrille is found in Old French and was borrowed into Middle English as cocodril (le). It was larger than a modern-day alligator and possessed a skull that resembled that of a crocodile rather than an alligator. All Rights Reserved.

The newfound fossil, unveiled today in the journal Nature, is the oldest definitive dinosaur discovered in Africa, dated to some 230 million years ago, during the Triassic period. The latest example of this trend is Tyrannoneustes, which was "diagnosed" from a 100-year-old museum specimen that had previously been identified as a plain-vanilla "metriorhynchid" (a breed of marine reptiles distantly related to crocodiles). The crocodile-like Desmatosuchus actually counted as an archosaur, the family of terrestrial reptiles that preceded the dinosaurs, and represented an evolutionary advance over other "ruling lizards" its kind such as Proterosuchus and Stagonolepis. Armadillosuchus, the "armadillo crocodile," comes by its name honestly: this late Cretaceous reptile had a crocodile-like build (albeit with longer legs than modern crocs), and the thick armor along its back was banded like that of an armadillo (unlike an armadillo, though, Armadillosuchus presumably couldn't curl up into an impenetrable ball when threatened by predators). Dibothrosuchus is technically classified as a "sphenosuchid crocodylomorph," not directly ancestral to modern crocodiles but more like a second cousin a few times removed; its closest relative seems to have been the even tinier Terrestrisuchus of late Triassic Europe, which may itself have been a juvenile of Saltoposuchus. 15 Largest Reptiles in the World, 5 Oldest Alligators in the World 10 Rarest Animals in the World It is estimated that they first appeared 450 million years ago. Vannini Hospital (Rome). These fossils have a fossil origin, which dates back 240 million years. Sarcosuchus long snout and large head make it appear fearsome. By the way, the similarity of Baurusuchus to another land-dwelling crocodile from Pakistan is further proof that the Indian subcontinent was once joined to the giant southern continent of Gondwana.

This prehistoric fossil is an incredible example of how prehistoric life lived, and its story serves as a reminder that protecting our environment is an essential part of our culture. Amphicotylus milesi: 150 million years ago, semi-aquatic, very similar to modern-day crocodiles, fossils found in the Morrison Formation in Wyoming. Along withpterosaursand dinosaurs, crocodiles were an offshoot of thearchosaurs, the "ruling lizards" of the early-to-middle Triassic period of the Mesozoic Era. Crocodiles live in the water as a large predatory reptile from the sauropsid family. It wasn't the biggest prehistoric crocodile that ever lived, but to judge by its long, muscular legs and streamlined body, Araripesuchus must have been one of the most dangerous--especially to any small dinosaurs prowling the riverbeds of middle Cretaceous Africa and South America (the existence of species on both these continents is yet more proof for the existence of the giant southern continent Gondwana).

Members of the crocodilian stem group, the clade Crurotarsi, appeared about 220 million years ago in the Triassic Period and exhibited . I have been keeping reptiles as pets for over 20 years, and I have also worked with reptiles in zoos and nature centers. Deinosuchus and its offspring grew smaller over the centuries, evolving into caimans and alligators. Born in the Okavango Delta in Botswana, Henry the Nile Crocodile, gained a reputation of being a man-eater, terrorizing local tribespeople and eating several men and children. The plant is considered a living fossil. The oldest fossil evidence of giant crocodiles in North America dates back 82 million years to Deinosuchus, which stood between eight and twelve meters in length and was around the same size as a modern crocodile. 5 Oldest Alligators in the World Crocodilians arose some 200 million years ago, when they prowled the land with early dinosaurs. "Prehistoric Crocodile Evolution." He was brought to the zoo in 1930 fully grown and was thought to be at least 85 years old, making him the oldest crocodile in the zoo's history.
