This fossil of a mammal biting a dinosaur captures a death battle’s final moments

A recently discovered fossil dating back to the early Cretaceous period, approximately 125 million years ago, challenges traditional perspectives on dinosaur predation and mammal submission by depicting a mammal attacking a dinosaur.

Describing the Fossil: The fossil showcases two intertwined skeletons, where a smaller mammal, Repenomamus, appears to be attacking a larger dinosaur, Psittacosaurus.
* The Repenomamus has its paw clutching the Dinosaur’s lower jaw, while the other grips a hind leg and its lower jaw is biting the dinosaur’s ribcage.
* The fossil was preserved due to the sudden eruption of an ancient volcano, resulting in immediate burial in ash and mud flows.

Challenging the Narrative: The fossil might alter the traditional belief that during the dinosaur era, mammals held a submissive role, with some serving as predators while certain dinosaurs were prey.
* The fossil’s situation suggests a more intricate, ancient food web.

Other Perspectives: While the clear depiction of the mammal attacking the dinosaur challenges traditional narratives, not everyone is convinced it represents a typical hunting scene.
* Paleontologist Elsa Panciroli suggested it’s possible that the Psittacosaurus was either in a weakened state or recently died.

Implication: This rare representation of a predatory act increases understanding of the food web dynamics of the Cretaceous period, suggesting that interactions between dinosaurs and mammals might have been more complex than previously believed.
* Despite this, it’s stressed that such smaller mammal attacking larger dinosaur scenarios were likely not common, and typically, dinosaurs preyed on the mammals.
