Mammal fossils have been found with dinosaurs in their stomachs! This fossil has the distinction of being the largest early mammal ever found. It’s about the size of a modern dog, over 20 times larger than most mammals (presumed) living in the early Cretaceous Period.
“This incredibly well-preserved fossil ‘Repenomamus robustus’ had the remains of a small dinosaur in its belly. It is evidence that mammals dined on dinosaurs.”
National Geographic. A mammal fossil was found with remains of dinosaur in its stomach.
In 2005 researchers in China identified a small dinosaur known as Psittacosaurus amongst the stomach region of a fossilized furry mammal that resembled a Tasmanian devil. To find such an advanced predatory mammal came as a surprise to these researchers. The evolutionists had long maintained that the only mammals alive at the time of the dinosaurs were very small, like the supposed human ancestor that resembled a squirrel!”
