Acknowledgments MPC-D 107/15 was found on August 22, 2007 by Federico Fanti, and excavated by the authors of this paper and a team from ‘‘Dinosaurs of the Gobi’’ under what were at times difficult circumstances. The specimen was prepared by Clive Coy (currently at the University of Alberta, Edmonton). MPC-D 107/16 was found and collected on the following day (August 23) by Nick Longrich. Specimens described in this paper were illustrated by Marco Auditore, who also provided enlightening discussions on oviraptorid anatomy.
