Silesaurus opolensis

† Silesaurus opolensis is a Late Triassic silesaurid dinosauriform from Poland, an important taxon for understanding the origins of dinosaurs. Its gracile build, herbivorous dentition, and beak-like rostrum make it a key phylogenetic outgroup to Dinosauria.

Diet & Feeding

Herbivore

Silesaurus opolensis 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

Triassic Late Mesozoic Era

Silesaurus opolensis lived during the Triassic Late period of the Mesozoic Era, approximately 237.0 to 201.4 million years ago.

The first true dinosaurs appeared during the late Triassic, including early theropods like Eoraptor and Herrerasaurus. Dinosaurs were still small and not yet dominant. The period ended with the Triassic-Jurassic extinction event.
