Yanornithiformes is an
The family Songlingornithidae was first named by Hou in 1997 to contain the type genus, Songlingornis.[1] Clarke et al. (2006) was first to find a close relationship between Songlingornis and the "yanornithids", which had been previously named to contain the similar species Yanornis and Yixianornis. At least one study has found Hollanda from the Late Cretaceous of Mongolia to be a member of this group.[2] The family Yanornithidae (now Songlingornithidae) had been placed in its own order containing no other families, named Yanornithiformes, in 2001.[3]
Beginning in 2012, multiple studies began to recover the songlingornithids in a clade with the hongshanornithids, a group of smaller, more specialized ornithuromorphs from the same time and place as some of the songlingornithids.[4][5] Other studies however continued to place the hongshanornithids just outside the yanornithiform clade.[2]
