Diagnosis
ReferenceDiagnosis
R. M. Hunt 2009Smallest species of Borocyon, with basilar skull length of ,245 mm, and c– m2 length of ,97–100 mm, averaging small- er than both B. niobrarensis and B. robustum
in body size and dentition (figs. 17, 18; tables 2, 3), and in males, by a more developed bony exostosis on the distal radius. Differs from Daphoenodon superbus (basilar skull length, 215–222 mm) by its greater size, longer forelimbs, larger m1 (fig. 18A), a ‘‘folded’’ M2, and proportionately longer m2 (fig. 18B).
