Where: Socorro County, New Mexico (33.5° N, 106.2° W: paleocoordinates 33.9° N, 70.3° W)

• coordinate stated in text

When: Hartland Shale Member (Greenhorn Limestone Formation), Late/Upper Cenomanian (99.6 - 93.5 Ma)

• Metoicoceras mosbyense biozone

• "During the Cenomanian and Turonian, foreland pasin subsidence and tectonoeustatic sea-level rise resulted in widespread marine flooding of the Western Interior U.S."
• "is characterized by finey and evenly laminated, pyritiferous, dark calcareous shale with high levels ofpreserved organic carbon (3-4 wt. %) and relatively depauperate faunal assemblages."

Size classes: macrofossils, mesofossils, microfossils

Preservation: mold/impression, original aragonite, original calcite

Collection methods: bulk,
