A new parvicursorine alvarezsauroid theropod specimen IVPP V20341 from
the Upper Cretaceous Wulansuhai Formation of Bayan Mandahu, Inner
Mongolia, China is described. IVPP V20341 appears to be
distinguishable amongst alvarezsauroids by cervical proceoly and
relatively larger semi-circular neural canals, but these features are
not proposed as autapomorphies because current knowledge of
alvarezsauroid necks and tails remains sparse. IVPP V20341 is
distinguishable from Linhenykus - the sole parvicursorine at Bayan
Mandahu - by 13 anatomical features that mostly relate to cervical and
caudal vertebrae. However, it is unclear how these vertebral elements
compare positionally along the spine, so more complete future finds
could revise the observed differences. Thus, there are still seven
parvicursorine species from the Cretaceous Gobi Basin after the
discovery of IVPP V20341.
