Sauropod Parents Abandon Hatchlings Fueling Predators

A new study led by University College London, published Feb. 1, 2026 in the New Mexico Museum of Natural History and Science Bulletin, maps Late Jurassic food webs in the Morrison Formation. Researchers analyzing Dry Mesa fossils found baby sauropods served as the primary prey for predators such as Allosaurus and Ceratosaurus, enabling predator survival and influencing later T. rex evolution.
