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. Despite that fact, they are still often seen as a threat and shot, giving them long term injuries and months of suffering before a slow death. The animal is . Often, the "wow factor" of a prehistoric creature's name is inversely proportional to how much we actually know about it. In what is now Uzbekistan, the first fossils of Sarcosuchus were discovered during the Early Cretaceous Period. The same area yielded fossils of chameleons that are unique in Greece, as well as snakes, lizards, turtles and frogs. This crocodile was estimated to weigh approximately 17,600 pounds and be 40 feet long when it was discovered. Paleontologist Tyler Lyson points to a crocodilian fossil embedded in a rock concretion. Where have fossilised deinosuchus fossils been found? The first crocodiles were from the Triassic period about 240 million years ago. 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. During the middle Triassic period, about 230 million years ago, archosaurs started to branch off in three evolutionary directions: dinosaurs, pterosaurs, and ancestral crocodiles. There is Muja (in Zoo in Belgrade), he has been moved to Serbia in 1937. as an older alligator. The discovery of the fossil in 2010 was made by the Australian Age of Dinosaurs Museum, in association with . If you crossed a dog with a crocodile, you might wind up with something like the early Jurassic Dibothrosuchus, a distant crocodile ancestor that spent its entire life on land, had exceptionally sharp hearing, and trotted around on four (and occasionally two) very canine-like legs. They can be found in sedimentary rock, which forms when layers of sand, silt, and clay settle on top of one another. This is a unique feature, never before seen in any crocodile species, modern or ancient. Worlds oldest crocodile fossil discovered in Portugal. However, because their sister group was present in the Cretaceous, gavialids must be at least that old; we simply haven't found fossils of their earliest representatives yet. Some 96 million years ago, the suburbs of Dallas, Texas, were part of a lush river delta that was home to turtles, dinosaurs, fishand a bizarre creature that looked like a crocodile but may have.

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). Giant crocodiles once roamed the Great Bear Rainforest of northeastern British Columbia. Location: Cairns, Australia. But other physical traits ofTriassic-andJurassic-era crocodiles, such as bipedal postures and vegetarian diets, were quite distinctive. We do know that Neptunidraco was a "metriorhynchid," a line of marine reptiles distantly related to modern crocodiles, the signature genus of which is Metriorhynchus (to which the type fossil of Neptunidraco was once referred), and that it also seems to have been an unusually fast and agile swimmer. WATCH: Sharks biting alligators, the most epic lion battles, and MUCH more. They are the. Mr. Freshie was caught in 1970 by crocodile wrangling duo Steve Irwin and his father, Bob Irwin, in the Moorehead River. Unfortunately, while it has the more impressive name, Terrestrisuchus may wind up being assigned as a juvenile of another genus of Triassic crocodile, Saltoposuchus, which attained more impressive lengths of three to five feet. The most common habitat for them is near shallow ocean waters, in sandy or muddy bottoms. Species: Saltwater Crocodile (Crocodylus porosus) Clearly, Smilosuchus was the apex predator of its North American ecosystem, likely preying on smaller, plant-eating pelycosaurs and therapsids. Although World War II ended over 60 years ago, paleontologists are still feeling the effects today. 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. It was lodged in a slab of rock dug up in 1947 in New Mexico by a team led by Dr. Edward Colbert, a. 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.. PaleoEquii/Wikimedia Commons/CC BY-SA 4.0. Henry lives in a nature preserve in South Africa. Currently awarded the title of largest crocodile in captivity by the Guinness Book of World Records, Cassius is a whooping 5.48 meters (17 ft 11.75 in) long. Species: Freshwater Crocodile (Crocodylus johnsoni) What set the phytosaurs (an offshoot of the archosaurs that preceded the dinosaurs) apart from early crocodiles was the position of their nostrils, which were located on the tops of their heads rather than on the ends of their snouts (there were also some subtle anatomical differences between these two types of reptiles, which only a paleontologist would be much concerned with). If those bones had been preserved, experts may, by now, have conclusively solved the riddle of this crocodile's diet: it seems that Stomatosuchus fed on tiny plankton and krill, much like a baleen whale, rather than on the land and river animals that populated Africa during the middle Cretaceous period. The earliest fossil evidence we have of this species dates back to the Pliocene Epoch, which spanned from 5.3 million to 2.6 million years ago. Send us your comments or opinion on this article. Stomatosuchus: 100.5-93.9 million years ago, large crocodile but toothless on the bottom, had a pelican-like pouch under its snout, scientists are curious what it ate, about 32 feet long, fossils found in Egypt. But how do these ancient creatures end up as fossils? Notosuchus: 85 million years ago, one of the first crocodiles thought to be entirely terrestrial (living on land only), about 5 feet long, fossils found in Argentina, Patagonia. Smilosuchus: 237-201.3 million years ago, two species of different sizes, both had long legs and a long snout, the smaller was around 16 feet, the larger was around 22 feet, fossils found in Arizona. But the crocodile family is much older. Isisfordia: 100.5-93.9 million years ago, small Australian crocodile, 3 feet long, looked similar to modern-day croc, fossils found in Australia. Over time, the sediment hardens and the organic matter decays, leaving behind an imprint or fossil of the organism. Erpetosuchus: 237-201.3 million years ago, one of the oldest crocodiles, walked similar to a greyhound, almost two feet long, smaller crocodile, fossils found in Scottland and Connecticut. Big Daddy married Sasha and Salma in December 2016. What puts Protosuchus firmly in the crocodile category are its well-muscled jaws and sharp teeth, which interlocked firmly when its mouth was closed. Species: Saltwater Crocodile (Crocodylus porosus) Location: Kwa-Zulu Natal, South Africa.

Another violent man eater, this crocodile named Big Daddy, was captured in 1986 after he mauled five people in River Tana. Geosaurus: 163.5-100.5 million years ago, genus of short-snouted marine crocodiles, around 10 feet long, fossils found in France and Germany. How old is the crocodile fossil? Location: Yekaterinburg, Russia. The fossil, described in a study in the. As marine reptiles go, you can't ask for a better name than Neptunidraco ("Neptune's dragon"), but otherwise there has not been a lot published about this middle Jurassic predator. 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. Prehistoric Amphibian Pictures and Profiles. . The specimen was unearthed in 2014 during excavations in an . Few things in natural history are as obscure as the difference between crocodiles and alligators; suffice it to say that modern alligators (technically a sub-family of crocodiles) are restricted to North America, and are characterized by their blunter snouts. This ocean-going crocodile was characterized by its long, narrow, tooth-studded snout, relatively stubby arms and legs, and the tough armor plating along its back--which must have been an effective form of defense, since the various species of Steneosaurus span a full 40 million years, from the early Jurassic to the early Cretaceous periods. Recently discovered in North Carolina, Carnufex was one of the largest "crocodylomorphs" of North America, and may well have been the apex predator of its ecosystem (the first true dinosaurs evolved in South America at about the same time, and tended to be much smaller; in any case, they didn't make it to what would become North America until millions of years later). - 17 Jan 2023, 19:02, In News, Portugal, World Since then, a number of new species have been discovered, some of which are more closely related to crocodilians than to other reptiles. Like many extinct animals that were discovered and named in the early 19th century, Pholidosaurus is a true taxonomic nightmare. Dmitry Bogdanov/Wikimedia Commons/CC BY 3.0.
