Taxonomic list

• most of the material is from SDSNH 3755, but original list of Walsh 1991 pertained only to SDSNH 3493
SDSNH 3493 and 3755 are from the Lower Member, and SDSNH 3757 is actually from the overlying Miramar Sandstone; however, I cannot determine if the taxa listed are restricted to SDSNH 3757, or what else it might contain
late Uintan
