Parazhelestes
sp.
Revised diagnosis:
Differs from
Zhelestes
by diastema between upper canine and premolars absent; diastema posterior to P1 absent; P3 double-rooted (unknown for
P. robustus
). Differs from
Zhelestes
and
Eoungulatum
by double-rooted upper and lower canine. Differs from
Aspanlestes
and
Zhelestes
by P1 double-rooted; protocone labially shifted more than 21%. Differs from
Aspanlestes
,
Zhelestes
, and
Eoungulatum
by mandibular symphysis at p2 or more anterior; trigonid angle less than 35°. Differs from
Eoungulatum
by P5 protocone smaller than paracone; P5 metacone swelling; P5 para- and metastylar lobes subequal; upper molars preparastyle present; metacone slightly smaller than paracone; ‘coronoid’ facet absent; masseteric fossa bordered ventrally by welldefined crest connected to condyle; m3 subequal to larger than m2.
Distribution:
Uzbekistan
; Late Cretaceous (Turonian-?Coniacian).
