Newly Identified Bird-Like Dinosaur May Be First Known Fruit-Eating Specialist, Study Finds

A newly identified bird-like dinosaur species, *Infernogallus jamesi*, may represent the first known dinosaur specialized in fruit-eating, according to a study published in the journal Nature Communications. Researchers analyzed the creature's skull anatomy and chewing muscles to reconstruct its diet, distinguishing it from the traditional view of dinosaur diets focused primarily on meat or general plant matter.

Anatomy and Fossil Discovery

• Fossil Site: Discovered in the Hell Creek Formation across parts of Montana, North Dakota, South Dakota, and Wyoming in the United States.
• Physical Traits: A relatively small, feathered, two-legged dinosaur weighing approximately 12 kilograms, comparable in size to a turkey.
• Classification: Belonged to the caenagnathid group, a lineage of toothless, beaked oviraptorosaurs.

Researchers utilized CT scans to examine the skull structure and jaw muscle arrangement. The study reported that the palate curved downwards into the oral cavity, altering muscle orientation and allowing the lower jaw to move backward and forward. This biomechanical arrangement shows parallels with certain modern fruit-eating parrots, such as the vulturine parrot.

Ecological Context and Implications

• Cretaceous Period: The era featured the diversification and increasing prominence of flowering plants (angiosperms).
• Dietary Scope: The anatomical evidence suggests suitability for processing fleshy fruits with soft flesh and central seeds, though researchers note the evidence does not establish exclusive fruit consumption, as other soft plant material may have been consumed.
