Anhuilong (meaning "Anhui dragon") is a genus ofmamenchisauriddinosaur known from theHongqin Formation ofAnhui province,China. The genus contains a single species,Anhuilong diboensis.[1]
Anhuilong is known from theholotypeAGB 5822, a forelimb consisting of a lefthumerus,ulna, andradius.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]
Renet al. (2020)[nb 1] recoveredAnhuilong as thesister taxon ofHuangshanlong, with the closest relative of this clade beingOmeisaurus tianfuensis. The results of their phylogenetic analysis are shown in the cladogram below:[1]
