May 2007: Kaiparowits Formation, Southern Utah.
Purpose: The Late Cretaceous Kaiparowits Formation is a vastly untapped paleontological resource that has previously yielded the associated remains of an avisaurid enantiornithine, the most complete North American enantiornithine known. This bird remains undescribed so the purpose of this field expedetion was to attempt to discover new material. Needless to say, while my team, which consisted of Graduate Students in Residence Zhijie "Jack" Tseng - Mammal expert/Biologist extraordinaire (photo, foreground), two USC Earth Science undergraduates (Abraham Padilla and Glen Fischer; photo back right and left), and three additional volunteers (Jane Mitchell, Yinmai O'Connor, and Mario Giron) did manage to collect a nice sampling of mammals (3+ genera) and theropods (5+ forms) as well as collect some eggshell fragments and a Ceratopsian vertebra, no unequivocal bird material was uncovered.
