Juvenile Sauropods Were Key Prey for Late Jurassic Predators, Study Finds
On January 30, 2026, a study led by Dr. Cassius Morrison from University College London was published, revealing that juvenile sauropods were a primary food source for carnivorous dinosaurs during the Late Jurassic period, approximately 150 million years ago. The research analyzed fossils from the Dry Mesa Dinosaur Quarry in the United States and reconstructed the food web of that era.
The findings emphasize the significant ecological role of young sauropods within the Morrison Formation ecosystem. Juvenile sauropods served as a major prey for meat-eating dinosaurs, significantly influencing the dynamics of the Late Jurassic food web.
This study provides new insights into predator-prey relationships during the Late Jurassic, highlighting the importance of juvenile sauropods in sustaining carnivorous dinosaur populations and shaping ancient ecosystem structures.
