“…Maip , from the Chorillo Formation, is not the only record of Megaraptoridae from the uppermost Cretaceous, although it is currently the most complete. In addition to Maip, the Chorrillo Formation has yielded at least four additional megaraptorid specimens: an isolated dorsal centrum (MPM 21,546); an isolated tooth (MACN-Pv 19,066); and two sets of associated teeth (MPM-PV-22864–5 3 , 39 ). It must be said, however, that comparisons of the isolated dorsal centrum (MPM 21,546) with unenlagiids, such as Unenlagia, better suggests that this bone might pertain to Unenlagiidae rather than to Megaraptoridae.…”
