About 56 million years ago, when Earth experienced a dramatic rise in global temperatures, one meat-eating mammal responded in a surprising way: It started eating more bones.

That’s the conclusion reached by a Rutgers-led team of researchers, whose recent study of fossil teeth from the extinct predator Dissacus praenuntius reveals how animals adapted to a period of extreme climate change known as the Paleocene–Eocene Thermal Maximum (PETM). The findings, published in the journal Palaeogeography, Palaeoclimatology, Palaeoecology, could help scientists predict how today’s wildlife might respond to modern global warming.

In a new study published in the BMC Biology, researchers in the Department of Organismic and Evolutionary Biology at Harvard, analyzed 156 limbs from 28 O. serratus fossil specimens to reconstruct the precise movement and function of these mysterious ancient arthropod appendages—shedding light on one of the planet’s earliest and most successful animals.
