Mirischia asymmetrica

† Mirischia asymmetrica is an Early Cretaceous compsognathid theropod from Brazil's Santana Formation. Approximately 2 m long, it is notable for preserved soft tissue that revealed air sacs, suggesting avian-like respiratory anatomy.

Diet & Feeding

Carnivore

Mirischia asymmetrica was a meat-eating predator. Carnivorous dinosaurs were active hunters or scavengers, equipped with sharp teeth and claws for catching and consuming prey. They occupied the top of the food chain in their ecosystems.

Time Period

Cretaceous Early Mesozoic Era

Mirischia asymmetrica 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.
