Collection method comments: Sternberg describes a wider collection: "Besides the specimen here described and those collected by Brown, the writer is aware of two skulls and one skeleton which have been collected from this horizon, and two skeletons, too poorly preserved to collect, and numerous disarticulated bones were observed. Most of these specimens are probably referable to A. ornatus." All are included here except for those collected by Brown.
