Birgeria
Discussion
Stensio placed Xenesthes velox Jordan 1907 in Birgeria, but it's not clear why he did that, as Xenesthes is the senior name.
Taxonomy
Birgeria was named by Stensiö (1919) [Sepkoski's age data: Tr l J l]. It is not extant. It is the type genus of Birgeriidae.
It was assigned to Palaeoniscidae by Stensiö (1921); to Palaeonisciformes by Sepkoski (2002); and to Birgeriidae by Lehman (1952), Savage and Large (1966), Beltan (1968), Bürgin and Furrer (1992), Chrzastek (2008) and Ni et al. (2017).
