Oviraptoridae

Part of speech: noun

Definitions

1. A family of bird-like theropod dinosaurs known for their distinctive short skulls and toothless beaks, primarily from the Late Cretaceous period; notable for their presumed egg-eating or egg-incubating behavior; distinguished by unique skeletal features including robust arms and hollow bones
2. A group of small to medium-sized feathered dinosaurs that lived during the Late Cretaceous, characterized by a beak without teeth and a likely warm-blooded metabolism; often associated with nesting sites indicating brooding habits; identified by anatomically specialized jaws and hands
3. A clade of carnivorous or omnivorous dinosaurs with bird-like traits including toothless jaws and specialized cranial crests, dating from the Late Cretaceous era; often linked to evidence of parental care through fossilized eggs and nests; marked by their distinct skeletal adaptations such as elongated neck vertebrae and powerful forelimbs

Etymology: The name rests on a misreading. The first specimen of the genus "Oviraptor," found in Mongolia, was lying on top of a nest of eggs, so its discoverers assumed it had been raiding them and called it "egg thief." Later finds showed that these animals were actually brooding their own eggs, but the genus name stuck, and it now lends its label to the whole group. The family name is formed from the genus name with the suffix "-idae," which zoologists use for family-rank names. The genus itself combines Latin "ovum," meaning egg, with "raptor," meaning plunderer or robber, the same root behind English "raptor" for birds of prey.
