Linheraptor is a
dromaeosaurid dinosaur which lived in what is now China in the Late Cretaceous. It was named by Xu Xing and colleagues in 2010, and contains the species Linheraptor exquisitus.[1] This bird-like dinosaur was less than 2 m (6.5 ft) long and was found in Inner Mongolia
. It is known from a single, nearly complete skeleton.
Discovery
Researchers announced the discovery of the genus after a nearly complete fossilised skeleton was found in 2008 by
Djadokhta Formation which have yielded the closely related dromaeosaurids Tsaagan and Velociraptor.[1] The holotype specimen of Linheraptor, articulated and uncompressed, is one of the few nearly complete skeletons of dromaeosaurid dinosaurs worldwide.[1] The name of the genus refers to the district of Linhe, Inner Mongolia, China where the specimen was discovered, while the specific name, exquisitus, refers to the well-preserved nature of the holotype (IVPP V 16923).[3]
Description
Linheraptor was a bird-like
theropod dinosaur. It was a dromaeosaurid which measured approximately 1.8 metres (5.9 ft) in length,[1] and weighed up to approximately 25 kilograms (55 lb).[4] At that size, Linheraptor would have been a fast and agile predator, perhaps preying on small ceratopsians.[5] Like all dromaeosaurids, it had an elongated skull, a curved neck, an enlarged toe claw on each foot, and a long tail; Linheraptor was bipedal and carnivorous. The large toe claws may have been used for capturing prey.[5]
Taxonomy
Among its sister taxa, Linheraptor is believed to be most closely related to derived dromaeosaurids such as Velociraptor.[1] Senter (2011) and Turner, Makovicky and Norell (2012) argue that Linheraptor exquisitus is a junior synonym of Tsaagan mangas,[6][7] but Xu, Pittman et al. (2015) reject this synonymy by responding to the counterarguments proposed using new and existing details of Linheraptor's anatomy.[2] A monographic description of Linheraptor is currently in preparation.
