EPSS Professor Aradhna Tripati is co-leader in a project across UCLA, UC Merced, and William Paterson University that discovered that the largest marine predator that ever lived was no cold-blooded killer, but in fact warm-blooded.
UCLA Newsroom writes that the project, which analyzed isotopes in the tooth enamel of the long-extinct ancient shark, "sheds light on the warm-blooded animal’s ability to regulate its body temperature — and might help explain why it went extinct."
