Where: Colorado (39.5° N, 104.7° W: paleocoordinates 45.7° N, 82.5° W)
• coordinate based on nearby landmark
When: Denver Formation, Puercan (66.0 - 63.3 Ma)
• Denver Formation (D1 sequence); nine meters stratigraphically above the K–Pg boundary and approximately three meters below DMNH loc. 2557
Environment/lithology: fluvial; sandstone
•microvertebrate materials at DMNH loc. 2560 are represented by two episodes of downcutting fluvial activity, each consisting of a >1 m-thick package of fine- to medium-grained sand and silt.
Size classes: macrofossils, mesofossils, microfossils
• "recovered vertebrate fossils consisted of disarticulated and disassociated hard parts (e.g., teeth, ganoid scales, vertebrae), predominantly ranging between 0.5 mm and 5 mm in size,
•with larger elements and scales up to 1 cm"
Reposited in the DMNH
