A new study, led by scientists at the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) in Beijing, China, including University of Bristol Ph.D. student Zhang Hanwen, examined the feeding habits of ancient ...
Today's baleen whales (Mysticetes) support their massive bodies by filtering huge volumes of small prey from seawater using comb-like baleen in their mouths much like a sieve. But new evidence reported in the journal Current ...
Predatory, bird-like theropod dinosaurs from the Upper Cretaceous (100.5-66 million years ago) of Spain and Canada all relied on a puncture-and-pull bite strategy to kill and consume their prey. But close examination of patterns ...
