Species Description
Palaeospiza bella is an extinct mousebird, known from the Upper Eocene Florissant Formation of Colorado. Initially described as the oldest known oscine passeriform (Allen 1878), it has recently been reinterpreted as a coliiform bird (mousebird). Palaeospiza bella represents the latest North American occurrence of a group whose living members occur only in modern Africa (Ksepka and Clarke, 2009).
