Litusilvanae

Litusilvanae is a proposed clade of birds, position as the sister clade to Aequorlitornithes.^[2] This clade comprises Gruimorphae (orders Charadriiformes and Gruiformes) and Strisores (the order Caprimulgiformes and the clade Vanescaves). While different lines of evidence from molecular, morphology and the fossil record has found support in the clades Gruimorphae^[3][4][5] and Strisores^[6][7][8] Wu et al. (2024) was the first to find support in such a novel sister group relationship between these two taxa.^[2]
