Brontopodus birdi

† Brontopodus birdi is a Late Jurassic sauropod ichnospecies from the Glen Rose Formation of Texas, United States, famous for trackways at Dinosaur Valley State Park. These large herbivore prints, attributed to a brachiosaurid sauropod, include a remarkable sequence where a theropod track appears to follow closely, possibly documenting predator-prey interaction behavior.

Diet & Feeding

Herbivore

Brontopodus birdi 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

Brontopodus birdi 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.
