Pamparaptor (, meaning "thief of the Pampas") is an extinct genus of paravian theropod dinosaur from the Late Cretaceous Portezuelo Formation of the Neuquén province in Argentine Patagonia. Its precise classification is uncertain, but the authors who described this taxon have argued that it is a dromaeosaurid. The genus contains a single species, P. micros (from the Greek word for "small"), which is known from a single specimen consisting of a mostly complete and fully-articulated left foot, which preserves the iconic dromaeosaur-like "killing claw". ==Discovery== The type and only specimen of
Pamparaptor (, meaning "thief of the Pampas") is an extinct genus of paravian theropod dinosaur from the Late Cretaceous Portezuelo Formation of the Neuquén province in Argentine Patagonia. Its precise classification is uncertain, but the authors who described this taxon have argued that it is a dromaeosaurid. The genus contains a single species, P. micros (from the Greek word for "small"), which is known from a single specimen consisting of a mostly complete and fully-articulated left foot, which preserves the iconic dromaeosaur-like "killing claw". ==Discovery== The type and only specimen of Pamparaptor was discovered in 2005 by a technician named Diego Rosales who was working for the Lake Barreales Paleontological Center (or CePaLB) at the National University of Comahue. It was found at a locality called the "Baal Quarry", which is an outcrop of the Portezuelo Formation dated to the late Turonian or early Coniacian. The locality is on the northern shore of Lake Barreales Lake and about northwest of the city of Neuquén.
The specimen was reposited at the National University of Comahue and was given the designation MUCPv-1163. It consists of all three metatarsals, a complete second toe including the ungual, and two phalanges each from the third and fourth toes from the left foot of the same animal. These elements were discovered in articulation with one another and so they can be reasonably inferred to have been from the same animal.
