Also known as USGS M4109
Where: Yukon, Canada (60.2° N, 140.6° W: paleocoordinates 65.0° N, 116.8° W)
• coordinate estimated from map
• small collection-level geographic resolution
When: Kulthieth Formation, Late/Upper Paleocene (58.7 - 55.8 Ma)
• Kulthieth Formation is part of a belt of Paleogene sedimentary and volcanic rocks that fringes the margin of the Gulf of Alaska. At the fossil locality at least 3,900 ft of the Kulthieth Formation is exposed in a homoclinal sectiuon that strikes roughly north and dips between 90 and 75 degrees. The sequence consists predominantly of uniformly bedded, light-gray to greenish-gray, hard, arkosic sandstone, pebbly sandstone, and sandy pebbly conglomerate.
• bed-level stratigraphic resolution
Environment/lithology: marine; lithified, gray, green sandstone and lithified, pebbly sandstone
Size class: macrofossils
Preservation: mold/impression
Reposited in the USNM
