Demandasaurus darwini

†Demandasaurus darwini is an extinct rebbachisaurid sauropod from the Early Cretaceous of Burgos Province, Spain. This herbivore, named after Charles Darwin, bore the characteristic bifurcated neural spines typical of rebbachisaurids. Its discovery in Iberia contributed to understanding the Gondwanan origins and subsequent dispersal of rebbachisaurid sauropods.

Diet & Feeding

Herbivore

Demandasaurus darwini 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

Demandasaurus darwini 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.
