Amargasaurus cazaui

Amargasaurus was a small sauropod distinguished by two parallel rows of tall neural spines along its neck and back. These may have supported a sail of skin for thermoregulation or display, or may have been sheathed in keratin like horns.

Diet & Feeding

Herbivore

Amargasaurus 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

Amargasaurus 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.
