Supplement from: A diverse neornithine assemblage from the Cretaceous Atlantic coastline and the rise of modern avifaunas

Chase Brownstein, Joaquín Lara-Midkiff & John Nash
Extant birds (Neornithes) are one of the most widespread and diverse vertebrate lineages, but their early evolution is poorly understood. Although molecular analyses contend that most major extant bird lineages diverged during a period of explosive radiation following the Cretaceous-Paleogene (K-Pg) extinction, several enigmatic fossils from the latest Mesozoic suggest that some clades evolved before the end of the Cretaceous. We describe a historically collected bird assemblage from the Atlantic coastline and conclusively demonstrate its...
