Hypsiloichnus marylandicus

† Hypsiloichnus marylandicus — a Early Cretaceous dinosaur track ichnospecies from United States. Herbivorous browser tridactyl traces. These ichnofossils document locomotion behavior and paleoenvironmental data.

Diet & Feeding

Herbivore

Hypsiloichnus marylandicus 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

Cretaceous Early Mesozoic Era

Hypsiloichnus marylandicus lived during the Cretaceous Early period of the Mesozoic Era, approximately 145.0 to 100.5 million years ago.

The Cretaceous saw continued dinosaur evolution with the rise of ornithopods and early ceratopsians. Flowering plants first appeared and began to transform terrestrial ecosystems. Spinosaurus and other large theropods lived during this time.
