Diagnosis
ReferenceDiagnosis
M. C. Mihlbachler 2011Diplacodon is a horned brontothere genus most easily recognized by its distinctive nasal bone with thickened and
dorsally angled (upturned) lateral margins. This trait, previously an autapomorphy of D. elatus, is now a synapomorphy of the genus. Mihlbachler’s (2008) extended diagnosis of Diplacodon elatus is now applicable to the genus Diplacodon, with the ex- ception of comments regarding size.
