A “hell chicken” dinosaur, Infernogallus, is described as having a beak-like mouth and jaw movements suited to chewing rather than tearing flesh. Based on CT-scan evidence, researchers say its lower jaw moved laterally, implying a grinding “mortar and pestle” style of feeding instead of a scissor-like bite typical of many carnivorous dinosaurs.
The fossil comes from the Hell Creek Formation in Montana, where a well-preserved specimen was recovered in 2011. The reporting ties these anatomical features to a larger evolutionary question about how dinosaur diets and plant availability changed between roughly 72 and 66 million years ago.
Outlets largely converge on the central point that Infernogallus is presented as the first fruit-eating dinosaur, framed through its beak, toothless jaw design, and chewing mechanics. Differences in emphasis are mainly about naming, with some outlets foregrounding the nickname and basic description while others highlight the feeding mechanics implied by imaging.
