Yixianosaurus longimanus

† Yixianosaurus longimanus is an Early Cretaceous maniraptoran theropod from the Yixian Formation of Liaoning, characterized by exceptionally elongated arms and hands. Its extreme arm length has led to suggestions of arboreal habits or use of the forelimbs in prey capture.

Diet & Feeding

Carnivore

Yixianosaurus longimanus 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

Yixianosaurus longimanus 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.
