Evidence suggests that certain pterosaur species vomited food that they could not digest as pellets. A recent study published found direct evidence that a species of pterosaurs probably regurgitated its food. The scientists found pellets containing fish scales near two specimens of Kunpengopterus sinensis found in China, one adult and one juvenile.
