Isaberrysaura mollensis

† Isaberrysaura mollensis — a Middle Jurassic ornithischian dinosaur from Neuquén Province, Argentina. Medium herbivore (~5–8 m long); possibly a stegosaur relative or neornithischian. Exceptional preservation includes seeds in the gut region, providing direct evidence of fruit-eating in a Jurassi.

Diet & Feeding

Herbivore

Isaberrysaura mollensis 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 Middle Mesozoic Era

Isaberrysaura mollensis lived during the Jurassic Middle period of the Mesozoic Era, approximately 174.7 to 161.5 million years ago.

Dinosaur diversity continued to increase, with the evolution of large sauropods and diverse theropods. Stegosaurs first appeared, and the supercontinent Pangaea was breaking apart.
