That turtle sustained a 25-inch-long (60 centimeter) bite mark on its shell. Instead, all of the evidence incriminated the giant caiman Purussaurus — a behemoth that could grow up to 33 feet (10 meters) long, making it the largest  known non-marine predator after the extinction of non-avian dinosaurs, Salas-Gismondi said. You’ve just pictured a member of the Thalassocnus genus. Such animals include a giant sloth, an early horse, a porcupine, alligators and a prehistoric elephant relative called a mastodon. Researchers found a small Purussaurus jaw at the Pebas Formation by the Napo River in Peru. This is according to the analysis of an ancient butchering knife, which was found by archaeologists in Argentina. http://doi.org/10.1671/2429b. http://doi.org/10.1007/s10914-014-9280-7 37.89 ; Muséum National d'Histoire Naturelle; H.

In a study published in May 2018, postdoctoral researcher Eli Amson detailed his observation of their bone thickness. The two areas where the Thalassocnus sloth walked (and swam) were in what is now Chile and Peru. ), "With this bite force, adult Purussaurus individuals were able to incorporate into their diet whatever, no matter the size or hardness," Salas-Gismondi said. Features in their jaws suggest that they grazed on seaweed and sea grasses from shallow coastal waters, likely less than one meter (3.3 ft) deep. An aquatic sloth from the Pliocene of Peru. The 175-pound animal’s shin from a hind leg was found in modern-day Peru in 2004 and analysis reveals it dates back to when the area was a proto-Amazonian wetland. Some people now think that it may have been alive in the 1800s. Predation of the giant Miocene caiman Purussaurus on a mylodontid ground sloth in the wetlands of proto-Amazonia. As an adult, this caiman had a bite force estimated at 7 tons (6.3 metric tons), more than four times the strongest bite ever measured in living and extinct animals, according to earlier research.

For now, we have to be content that the bones Thalassocnus left behind gave us the chance to observe their evolution in such great detail. But the swimming sloths—named Thalassocnus —lived along the beaches of Peru between 8 … Turns out, they're far more ancient than they look, estimated to be at least 8,000 to 10,000 years old, and no known geologic process can explain them. Giant ground sloths went extinct about 13,000 years ago, but the avocado lives on.” The museum houses its own giant ground sloth. Such an evolutionary trend is called bone mass increase (BMI), which involves the increase of the bone’s robustness (pachyostosis) or density (osteosclerosis). NY 10036. It wasn't immediately clear what had left the 46 bite marks on the sloth's left tibia. Although they are now extinct, some people believe that the reported sightings of the mapinguari are actually evidence that the giant ground sloth is not actually extinct, but still lives deep in the Amazon rainforest. Crocodylians often leave this many bite marks on a single bone, said Stephanie Drumheller-Horton, a paleontologist at the University of Tennessee in Knoxville, who wasn't involved with the study. The giant ground sloth, Megatherium, was once one of the largest mammals to walk the earth, bigger than a modern elephant. The attack likely happened in a flash, and ended with the caiman leaving nearly 50 tooth marks in the sloth's hind leg, a new study finds.

Besides their bulk, these sloths were distinguished by their significantly longer front than hind legs, a clue that they used their long front claws to rope in copious amounts of vegetation. They would have been some of the first humans to reach the Amazon. Following the extinction of non-avian dinosaurs, the largest Cainozoic continental predator was neither a Mammal nor a Bird, but the Giant Caiman Purussaurus.
