Phylogenetic position of Leinkupal laticauda, gen. n. sp. n.
(A) Strict consensus tree recovered after the inclusion of Leinkupal laticauda in a published data matrix focused on Diplodocoidea relationships [21]. (B) Most parsimonious tree recovered after the inclusion of Leinkupal laticauda in another published data matrix focused on Diplodocidae relationships [22]. Support values (Bremer/Bootstrap) of principal nodes are in brackets.
