Diagnosis
ReferenceDiagnosis
P. D. Gingerich 2007Stromerius is distinctive among basilosaurids in having unusually long and forwardly-directed metapophyses on lumbar vertebrae (Fig. 3). In addition, Stromerius retains ananticlinal-like penultimate thoracic vertebra with a vertical neural spine (Fig. 1C), which differs from the anteriorly directed spine of L2 in the same specimen. Stromerius retains a relatively short lumbus seemingly comprising only 12 vertebrae, the last four of which are identifi able as
sacral homologs (Fig. 3). In addition, Stromerius nidensis differs from contemporary Saghacetus osiris in being larger, and from older Dorudon atrox and/or D. stromeri in being smaller (Fig. 4). Stromerius nidensis is the only species of the genus known to date.
