Alvarezsauridae

Alvarezsauridae is a family of highly specialized theropod dinosaurs with extremely reduced forelimbs bearing a single enlarged claw. These small feathered insectivores ranged from the Late Cretaceous of Asia, North America, and South America. Their unique forelimb morphology is thought to have been used for excavating termite mounds or wood-boring insects. The family includes †Alvarezsaurus, †Mononykus, and †Shuvuuia.
