Sonorasaurus thompsoni

† Sonorasaurus thompsoni is an Early Cretaceous brachiosaurid sauropod from the Turney Ranch Formation of Arizona, USA. Among the few brachiosaurids from the Cretaceous of North America, it inhabited a semi-arid environment with seasonal flooding.

Diet & Feeding

Herbivore

Sonorasaurus thompsoni 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

Sonorasaurus thompsoni 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.
