When: Upper Member (Glen Rose Limestone Formation), Early/Lower Albian (112.0 - 109.0 Ma)
• Near Corbula bed
•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 Salenia texana Zone and Corbula bed fall within the mammillatum zone. 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.
