Are Omnivorous Dinosaurs Rare? Unraveling the Little-Known Diets of Ancient Creatures.
Unlike modern ecosystems, which are filled with diverse omnivores, the Earth during the dinosaur age is believed to have had a clear division between carnivorous and herbivorous diets.
However, among these, a small number of omnivorous dinosaurs did exist.
Even within the theropod group—the archetype of carnivorous dinosaurs, which includes Tyrannosaurus—there were omnivorous species.

Gastornis
Gastornis
A giant, flightless bird that reached a height of about 3 meters, thought to have eaten both meat and plants based on the shape of its jaw.
Why Were Omnivorous Dinosaurs So Few?
Why were omnivorous dinosaurs a minor presence on ancient Earth?
The reason is still not fully understood.
However, as research progresses, there is a possibility that dinosaurs previously classified as carnivores or herbivores may be reclassified as omnivorous.
We look forward to future new discoveries.
