Some new findings a bout the agility and speed of Anteosaurs.
An ancient hippo-sized reptile may have been surprisingly agile
Some 260 million years ago, before the rise of dinosaurs, bone-crushing anteosaurs reigned as land’s largest predators. A new analysis of an anteosaur skull suggests that these hefty reptiles may have been relatively speedy.
“This contradicts what we knew about anteosaurs before,” says Ashley Kruger, a paleontologist at the Swedish Museum of Natural History in Stockholm. Based on the reptiles’ size, which was around that of today’s hippos or rhinos, researchers had pegged the Permian Period predators as sluggish beasts that waited to ambush prey. The skull of an Anteosaurus magnificus appears to tell a different story.
Relying on CT scans of fossil skull segments excavated in South Africa, Kruger and his team digitally reconstructed the long, bumpy noggin of a juvenile A. magnificus. They found that the animal’s inner ears — bony tubes that help with balance — dwarfed those of its peer predators. The shape of these bones also suggests that anteosaurs may have benefited from a rather large brain region used to coordinate motion while surveilling prey, the researchers report February 18 in Acta Palaeontologica Polonica. ...
