velociraptor (n.)

1924, from Latin velox (genitive velocis) "swift, speedy" (see velocity) + raptor "robber" (see raptor). Fossil remains discovered in 1923 in the red Djadochta sandstone at Shabarakh Usu in Mongolia.

The first (Fig. 1) of the typical megalosaurian type, although of small size, seems to have been an alert, swift-moving carnivorous dinosaur to which the generic name Velociraptor is applied.
