Diagnosis
ReferenceDiagnosis
J. D. Archibald and A. Averianov 2012Differs from Aspanlestes, Zhelestes, Parazhelestes, and Eoungulatum by tilting of coronoid process 95–105°. Differs from Aspanlestes, Zhelestes, and Eoungulatum by mandibular symphysis at p2 or
more anterior. Differs from Aspanlestes, Zhelestes, and Parazhelestes by ‘coronoid’ facet present; p5 metaconid absent; p5 lingual cingulid complete. Differs from Zhelestes, Parazhelestes, and Eoungulatum by
Meckelian groove present. Differs from Aspanlestes and Parazhelestes by mandibular condyle slightly above alveolar level; p5 paraconid cingulid cusp absent. Differs from Eoungulatum by masseteric fossa bordered ventrally by well-defined crest connected to condyle; m3 subequal or larger than m2.
