Extinct genus of reptiles
Brachyuranochampsa is an extinct genus of crocodilian .
The only robust occurrence of Brachyuranochampsa is B. eversolei from the Middle Eocene of Wyoming .[1] Another species, B. zangerli from the lower Bridger Formation at Grizzly Buttes, has been synonymized with another primitive crocodilian, "Crocodylus" affinis , also known from the Bridger Formation.[2] [3]
Phylogenetic studies have consistently recovered Brachyuranochampsa as more basal than the crown group Crocodylidae , which consists of all extant (living) crocodiles .[2] [4]
The below cladogram from a 2018 study combining morphological data and molecular DNA evidence shows the placement of Brachyuranochampsa within Crocodylia .[5]
