I sent this yesterday but it apparently evaporated in cyberspace.
Apologies if some people received the earlier version.

A new paper.

The First Basal Neoceratopsian Dinosaur from the Lower Cretaceous,
Kanmon Group in Kyushu, Southwestern Japan.

An isolated tooth specimen from the Lower Cretaceous Kanmon Group in
Kyushu Island, south-western Japan was initially identified as a
hadrosaurid. It is reidentified herein as a neoceratopsian tooth based
on the presence of a wide and prominent primary ridge on the crown, a
shallow indentation on the right side of the primary ridge in
non-occlusal view, and a horizontally oriented cingulum at the base of
the crown. The poorly developed cingulum and shallow indentation
suggest that it does not pertain to a ceratopsid, but is only
referable to a basal neoceratopsian. This represents the first basal
neoceratopsian specimen from the Lower Cretaceous of Kyushu Island.
