Dinosaurs Ate Fruit Earlier Than Thought

Recent paleontological research published in the journal Science on November 9, 2026, reveals that non-avian dinosaurs and other prehistoric creatures may have consumed significantly more large, fleshy fruit than previously believed. Researchers analyzing a remarkably preserved 74-million-year-old fossil forest in New Mexico, often dubbed a botanical Pompeii, discovered ancient flowering plant reproductive structures and seeds roughly the size of modern grapes. The primary author, James Saulsbury from the University of Kansas Biodiversity Institute and Natural History Museum, along with his co-authors, challenges the longstanding evolutionary theory that large fruits and complex seed dispersal mechanisms exclusively evolved after the Cretaceous-Paleogene extinction event 66 million years ago. This discovery shifts our timeline of angiosperm reproductive ecology. The study demonstrates that modern-looking forest structures and diverse reproductive strategies were actively developing much earlier in the Cretaceous period than previously thought. The presence of grape-sized fruits indicates that large dinosaurs, alongside early mammals, actively participated in zoochory, serving as crucial agents for seed dispersal long before the asteroid impact. Researchers recommend re-evaluating co-evolutionary dynamics between prehistoric megafauna and ancient flora. By examining seed morphotypes from exceptional deposits like the New Mexico volcanic ash tuff, scientists gain a clearer window into ancient ecosystems, proving that plant-animal mutualisms in forest canopies were far more advanced during the Mesozoic era.
