Also known as UCMP V-72210; LACM 3103
Where: Garfield County, Montana (47.6° N, 107.0° W: paleocoordinates 54.0° N, 81.8° W)
• coordinate based on political unit
• small collection-level geographic resolution
When: Tullock Formation, Puercan (66.0 - 63.3 Ma)
• from the Billy Creek section and definitely in chron C29r: see Archibald et al. 1982, Swisher et al. 1993; the IrZ-Coal is apparently present in the section, although the HFZ-Coal is not, so the date of the IrZ-Coal can be considered a maximum
• group of beds-level stratigraphic resolution

Size class: mesofossils
Reposited in the LACM
Collection methods: bulk, surface (float), sieve,
