Paleontologists are gaining new insights into the diets of ancient predators thanks to a detailed analysis of fossilized stomach contents. A new study, published recently, details the discovery of what researchers believe is the oldest known terrestrial “regurgitalithe”- essentially, a fossilized vomit ball- shedding light on the feeding habits of Dimetrodon, an apex predator from the early Permian period. The find offers a rare glimpse into the prehistoric food chain and demonstrates the increasing value of these fossilized remains as direct evidence of ancient animal behavior.

Longtemps considérés comme de simples curiosités, les restes alimentaires fossilisés sont devenus de véritables preuves scientifiques. Une nouvelle étude décrit le plus ancien régurgitalithe terrestre connu et éclaire le régime alimentaire des premiers grands prédateurs terrestres.
