'Huge' Ancient Mammal Sheds Light On Evolutionary History
The discovery of one of the biggest mammals that lived alongside dinosaurs could shed light on how the early mammals evolved.By Sebastian Martinez | November 6, 2014
One of the largest mammals to ever live amongst the dinosaurs has been discovered ... and it's actually not that big.
This is Vintana sertichi, a mammal that lived some 66 million years ago and weighed in at some 20 pounds, making it the second-biggest mammal known to have lived alongside dinosaurs. (Video via WCBS)
DAVID KRAUSE, STONY BROOK UNIVERSITY: "Most mammals that lived during the age of dinosaurs were small, shrew-size, mouse-size. But this animal, Vintana, was huge. It was, say, twice the size of a modern groundhog. That is enormous during that interval of time."
