Abstract
"A systematic revision of the North American family Baenidae has resulted in the following conclusions: 1) The family ranges from Albian, early Cretaceous, to Uintan, late Eocene, in age. 2) Definite members of the family are presently known only from North America. 3) Eight genera including nine species are soundly based on skull material: Trinitichelys hiatti, new genus and new species; Hayemys latifrons (Hay), new genus; Plesiobaena antiqua (Lambe), new genus; Plesiobaena putorius, new genus and new species; Eubaena cephalica (Hay); Stygiochelys estesi Gaffney and Hiatt; Palatobaena bairdi, new genus and new species; Baena arenosa Leidy; and Chisternon undatum (Leidy). Four more genera with one species each are known only from shells: Compsemys victa Leidy; Neurankylus eximius Lambe; Boremys pulchra Lambe; and Thescelus insiliens Hay. The following are nomina dubia: Polythorax missuriensis Cope; 'Neurankylus' wyomingensis Gilmore; 'Baena' hayi Gilmore; 'Baena' nodosa Gilmore; Chisternon interpositum Hay; 'Baena' ornata Gilmore; and 'Baena' platyplastra Gilmore. 4) The family Glyptopsidae has the nearest ancestor in common with the family Baenidae; together they constitute the superfamily Baenoidea. A classification based in part on degree of morphologic diversity but consistent with the phylogeny is developed. A strictly phylogenetic classification is also presented"--P. 245.
