Stratigraphy
| Formation: | Moenkopi | Member: | Wupatki | ||

| Stratigraphy comments: Three fossil vertebrate horizons occur at Meteor Crater - the middle of these is the main quarry. The upper horizon is a "few centimetres" above this
Lucas & Schoch (2002: Lethaia 35, 97-106) inferred the Wupatki Member to be Spathian in age based upon lithostratigraphic correlation | |||||
