Anhuilong is a genus of mamenchisaurid dinosaur found in the Anhui province of China. It contains a single species, Anhuilong diboensis. Ren et al. (2018) recover Anhuilong as the sister taxon of Huangshanlong, with the closest relative to this clade being Omeisaurus tianfuensis.[1]
Discovery and naming[]
Anhuilong is known from the holotype AGB 5822, a forelimb consisting of a left humerus, ulna, and radius. It is distinguished by the following combination of features: low ratios of the average of the greatest widths of the proximal end, mid-shaft and distal end of the humerus/length of the humerus, total length of ulna to humerus and total length of radius to humerus; the lateral edge of the deltopectoral crest directs caudolaterally, the lateral accessory condyle on the craniodistal edge of humerus is more robust than the medial one, and the cross-sectional shape of the ulna at mid-shaft is elliptical with highest ratio of transverse to craniocaudal diameter among mamenchisaurids.[1]
