Fully intact 5-million-year saber-toothed cat skull pulled from museum drawer
A UC Berkeley postdoc identified a nearly complete skull of the 5-million-year-old saber-toothed cat Adelphailurus kansensis found in a drawer at the American Museum of Natural History. This marks the first fully complete skull of the species, offering new insight into saber-toothed evolution; researchers note that the upper canines were highly effective but fragile, and as large prey declined after the last ice age, these cats likely faced extinction around 10,000 years ago.
