Condorraptor currumili was a medium-sized theropod from the Central Jurassic of Argentina, which was described by Oliver Rauhut in 2005and of which several individuals have come down to us. However, it is unclear whether they allbelong to thesame taxon . Parts of the postcranium and teeth are preserved.
Condorraptor is one of the best known theropods of Central Jurassic in the southern hemisphere, although the postcranium is incomplete.
description
Condorraptor was discovered in the Cañadón Asfalto Formation , which is located in the Argentine province of Chubut . The name means "hunter from Condor" and refers to the fact that the site is 2.3 km west of Cerro Condor. The finds are around 166 to 163 million years old and come from the Callovian ( Middle Jurassic ).
The holotype (MPEF-PV 1672) includes a left shinbone (tibia) and possibly a toe bone. 31 paratypes are known, with the catalog numbers, MPEF-PV 1673-1697 or MPEF-PV 1700-1705. The material includes, but is not limited to, cervical vertebrae , vertebrae , ribs , thighs , fibulae and parts of the pelvis .
Due to the numerous material that can be assigned to many individuals, Condorraptor is considered to be one of the most complete theropods of the Central Jurassic in Gondwana . However, these copies could be just one. Characteristic features are the position of the lateral hollows and depressions in the shin and the absence of a posterior notch between the thigh and the shin. This taxon is important because it supports Oliver Rauhut's hypothesis that the theropod radiation occurred in the Jurassic period .
Systematics
Oliver Rauhut classified Condorraptor both in the first description and later in 2007 as a basic representative of the Theropoda group. Other authors see Condorraptor as a representative of the Spinosauroidea and close relatives of Piatnitzkysaurus .
In 2012, Condorraptor was classified by Carrano and colleagues in the family Piatnitzkysauridae along with Marshosaurus and Piatnitzkysaurus .
