Diagnosis
ReferenceDiagnosis
H. de Bruijn et al. 2003Ottomania proavita is a ctenodactylid of medium size with M1 and M2 with five crests and lower molars with four crests and three roots. Cheek teeth brachyodont. Protocone and hypocone sub-equal and connected by a low entoloph in the D4 and M1, rarely so in the M2 and M3. Anteroloph much lower than the protoloph in the D4 and M1, but successively more equal in height from M1 through M3. Permanent premolars non-molariform and very small. P4 with two cusps and one root, p4 with three cusps (lacking the hypoconid and the entoconid) and two roots. D3 with two cusps that are anteriorly and posteriorly connected by short crests. D4 very similar to the M1 in morphology and size, but more bunodont. The dental pattern of the molars becomes more lophodont, and overall less primitive, from D4/d4 through M3/m3.
