Discovery and naming

The holotype, LFGT LCD 9701–1, found in 1995, was in 2011 assigned to the contemporary genus Chuanjiesaurus.[2] However, in 2020, Ren et al. noted several differences between it and the holotype of Chuanjiesaurus, and so assigned it to a new taxon, Analong chuanjieensis. The binomial name means "Ana dragon from Chuanjie", where Ana is the village in Yunnan Province where the holotype was found.[1]

Classification

In a phylogenetic analysis, Analong was found by its describers to be the earliest diverging mamenchisaurid. Their resulting phylogenetic tree of Mamenchisauridae is reproduced below.[1]
