Dinehichnus socialis

†Dinehichnus socialis is a sauropod ichnospecies from the Late Jurassic of the American Southwest. The 'socialis' name reflects parallel trackways suggesting gregarious behavior, with multiple individuals moving in the same direction simultaneously. These Morrison Formation tracksites provide compelling evidence that sauropods traveled in herds.

Diet & Feeding

Herbivore

Dinehichnus socialis 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

Dinehichnus socialis 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.
