"Some Dinosaurs Regurgitated Pellets Just like Birds" Topic

"Picture yourself in the Early Cretaceous Period. Ahead of you, beyond the edge of an ancient forest, you see the feathery form of a Utahraptor. She's a large one – at least twenty feet long, and tall enough to easily rest her chin on your head. Mercifully, she's not close enough to do that. She's simply strolling by, totally unaware of you.

We don't know for certain whether Utahraptor ever barfed pellets like modern owls do. No one has found an appropriately-sized bolus of iguanodont and sauropod bone chunks in the Early Cretaceous strata of eastern Utah. But we know that some non-avian dinosaurs related to the famous raptors vomited pellets like modern birds do. The evidence, paleontologist Xiaoting Zheng and colleagues write, comes from the roughly 160 million-year-old strata of China…"
