Diagnosis

---|---|---|
B. P. Kraatz et al. 2013 | Protohummus dango is a thryonomyid rodent similar in size to the living Thryonomys swinderianus, with upper incisors possessing two grooves on their buccal sur- face, and molars and premolars lacking an anterolabial cuspid on the lower cheek teeth. In the presence of more than one upper incisor groove, Protohummus dango is distinguished from all thryonomyid rodents except Paraulacodus and Thryonomys. Protohummus dango is dis- tinguished from Paraulacodus spp. by the absence of an anterolabial cusp on the lower cheek teeth, a character that it shares with Thryonomys spp. It is distinguished from all living and fossil Thryonomys spp. by the absence of a metalophulid II on dP4. It is further distinguished from T. swinderianus, T. gregorianus, and T. wesselmani, by the presence of only two (rather than three) grooves on the upper incisor. |
