Also known as Locality 8
Where: Crook County, Wyoming (44.2° N, 104.7° W: paleocoordinates 42.7° N, 62.6° W)
• coordinate stated in text
• small collection-level geographic resolution
When: Mowry Shale Formation (Colorado Group), Late/Upper Albian (105.3 - 99.6 Ma)
• "Uppermost part of Mowry shale member of Graneros formation, 2 feet below base of Clay Spur bentonite bed" - but this assignment is used only in S Dakota, so interpreted here as Mowry Fm.
• bed-level stratigraphic resolution
Environment/lithology: marine; shale
Size class: macrofossils
