They were then preserved by being coated in seeping asphalt, along with an ancient horse, a deer, an armadillo-like pampathere, and an elephant-like gomphothere. Instead of falling into a tar pit and getting stuck, experts believe the giant animals died 20,000 years ago from drinking water contaminated by their own faeces. Weighing in at several tons, the sloths - of species Eremotherium laurillardi - had the ability to walk on two legs and move fast, unlike their languid modern relatives. The specimens - which include 15 adults, 5 juveniles and two newborns or fetuses - were unearthed from the Tanque Loma site on the country’s Santa Elena peninsula.
The fossil remains of 22 Ice Age sloths the size of elephants have been found preserved in asphalt in Ecuador, researchers have reported. They eventually whittled it down to a juvenile of the Purussaurus neivensis 22 Ice Age SLOTHS the size of elephants found preserved in asphalt in Ecuador
Researchers believed the marks on the bone were from a crocodilian but were unsure originally which of the seven known species it could be. Pictured, a Purussaurus tooth. A process of elimination removed six of the seven known crocodilians from this period of time for being either too small, weak or different shaped teeth and left the Purussaurus as the only possible perpetrator Pictured, a Purussaurus skull. Following the demise of the dinosaurs, the Purussaurus was the largest predator the world had seen and has no parallel in the modern world and had a bite twice as powerful as that of the T Rex Fossil remains of 22 Ice Age SLOTHS the size of elephants… Did it die of indigestion? 15-foot long ichthyosaur that… Mummified pup unearthed in Russia had feasted on a woolly… Ancient ‘hell ants’ had deadly scythe-like mandibles that….‘The bite was so powerful many teeth perforated the shinbone and collapsed extensive portions of the outer layer. ‘Unexpectedly, the Purussaurus leapt out and captured it by the lower hindlimb. However, the dentition did not align with the tooth marks of these animals, leaving the Purussaurus as the only possible perpetrator.Ĭorresponding author Dr Rodolfo Salas-Gismondi, of Cayetano Heredia University, Lima, said: ‘The bone bore 46 tooth marks. The 13-stone creature was meandering the swamps of primitive Amazonia. The proto-Amazonian wetlands in which the battle occurred had not yet been conquered by mammals and the only land-dwelling carnivores were a handful of marsupials. Writing in their paper, academics from Universidad Peruana Cayetano Heredia in Peru believe the predator grasped repeatedly at the leg and may have even tried to rip the limb from the body of the sloth.Ī process of elimination removed six of the seven known crocodilians from this period of time for being either too small, weak or different shaped teeth. The 46 teeth marks on the bone present key clues as to the identity of the animal responsible for the bite.

However, it is thought this specific predator was a youngster who was yet to reach its full size when it killed the sloth. Researchers analysing the bone believe the leg was clenched in the powerful jaws of the Purussaurus, the giant Miocene caiman which grew up to 20 ft long. 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.
