New research on the preserved gut contents of Microraptor reveals a more varied diet than previously believed. An international team of scientists discovered a rare piece of evidence suggesting that dinosaurs consumed mammals. A recent study in the Journal of Vertebrate Paleontology details the
specimens from this area have been found with gut contents of a fish, bird, and lizard, indicating that these small dinosaurs had diverse diets. However, it remains unclear whetherconsumed the contents in a predator-prey relationship or by scavenging. Researchers can only say conclusively thatSullivan says information about dinosaurs’ diets is a key piece in the puzzle to learning more about what was going on at the time they roamed the Earth.
“We’re slowly gathering pieces of information about these past ecosystems and the animals that inhabited them. So what this discovery does is fill in a little bit of information in that it’s showing the diet of“That tells us something about this animal and, by extension, tells us that there were generalist carnivores in these ancient ecosystems — that that niche existed.”included mammals” by David W.
