Laudate (Paleocene of the United States)

Also known as Laudate Discovery Site; UCMP V-5252 (= UCMP V-5502, RAM V94014), UCMP V-5870 (= RAM V94133)

Where: Kern County, California (35.5° N, 117.8° W: paleocoordinates 42.8° N, 100.7° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: 4a Member (Goler Formation), Tiffanian (61.7 - 56.8 Ma)

• believed to be Puercan or Torrejonian by McKenna et al., but "definitely Tiffanian" according to McKenna and Lofgren 2003

•from "near the base of information member 4b (formerly Tgsu)"

•Lofgren et al. 2014: The mammalian fauna from member 4a and the lower part of member 4b is collectively referred to as the Goler Assemblage. the Goler Assemblage is probably middle Tiffanian (Ti3–Ti4a), although a Ti5a age is also possible.

• member-level stratigraphic resolution

Environment/lithology: fluvial; conglomerate and sandstone

• "river"
• formation is "non-marine and then marine" going up section, and consists of "Almost 4 km of conglomerates, feldspathic sandstones, and drab or variegated mudstones"

Size classes: macrofossils, mesofossils

Collected by M. McKenna in 1955; reposited in the UCMP

Collection methods: bulk, surface (float), sieve,
