Galeamopus hayi

† Galeamopus hayi — a Late Jurassic diplodocid sauropod from the Morrison Formation, United States. Large herbivore (~24 m). Named for Dr. O. P. Hay. Long, peg-like teeth for raking vegetation. The skull morphology and neck proportions differ from other diplodocids, supporting its genus-level dist.

Diet & Feeding

Herbivore

Galeamopus hayi was a plant-eating dinosaur. Herbivores typically fed on ferns, cycads, conifers, and other vegetation available during their era. Many herbivorous dinosaurs developed specialized teeth and digestive systems for processing tough plant material.

Time Period

Jurassic Late Mesozoic Era

Galeamopus hayi lived during the Jurassic Late period of the Mesozoic Era, approximately 161,5 to 145,0 million years ago.

One of the most iconic periods for dinosaurs. Giant sauropods like Brachiosaurus and Diplodocus roamed alongside predators like Allosaurus. Archaeopteryx, the earliest known bird, appeared. The Morrison Formation preserves an extraordinary fossil record from this time.
