By Simona Kitanovska All teeth evolved from a single ancient sea predator, according to a new study. The study explains how certain species evolved to grow teeth by pinpointing their likely origin in an armored ray that swam the oceans 100 million years ago. They evolved from jagged spikes along the snout of the primitive
By Joseph Golder Scientists found about 20 large 80-million-year-old dinosaur eggs when they unearthed a titanosaur nesting site in Brazil. The dinosaur egg nest, which dates back to the Cretaceous period, approximately 145 to 66 million years ago, was discovered in an abandoned limestone mine in the rural area of Ponte Alta, in the southeastern
By Anamarija Brnjarchevska Mammals put brawn before brains to survive the post-dinosaur world, according to new research. Prehistoric mammals bulked up, rather than develop bigger brains, to boost their survival chances once dinosaurs had become extinct and were “fairly dim-witted” compared to mammals today, say Scottish scientists who led the study.

By Martin M Barillas The earliest known prehistoric saber-toothed predator, living west of the Rocky Mountains millions of years ago, has been described for the first time. Dubbed Diegoaelurus vanvalkenburghae, the cat-like predator was hyper-carnivorous, subsisting entirely on meat. Like the larger and better known saber-tooth cat, called Smilodon, it had saber-like teeth in its
By Joseph Golder Prehistoric giant sloths had armor like chain-mail, made of a bone mesh embedded in their skin to stop predators from sinking their teeth and claws into them, according to new research. Experts at the Paleontological Museum of San Pedro said the surprising find took place as they were conducting a “routine survey”
