USGS M4109 - Addicott and Plafker (1971) (Paleocene of Canada)

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

• The sequence consists predominantly of uniformly bedded, light-gray to greenish-gray, hard, arkosic sandstone, pebbly sandstone, and sandy pebbly conglomerate.

Size class: macrofossils

Preservation: mold/impression
