Also known as Albritton locality 8

Where: Comanche County, Texas (31.9° N, 98.6° W: paleocoordinates 29.7° N, 56.5° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Glen Rose Limestone Formation (Trinity Group), Early/Lower Albian (112.0 - 109.0 Ma)

• level 22

•The Glen Rose formation spans through four ammonite zones with ages between latest Aptian and early Albian. Young 1974 suggested the Kasanskyella spathi ammonite zone is latest aptian, the Hypacanthoplites cragini zone is earliest Albian, the Douvilleiceras mammillatum and Hypacanthoplites comalensis zones are early Albian and may extend into the middle Albian. The benthic foraminifera Orbitolina texana also suggests a late aptian - early albian age and is found in basal levels and in the upper member (Stricklin et al. 1971). Scott et al. (2007) estimated that the age of the Glen Rose Formation ranges from 113.3 to 108.0 Ma.
