, the Eastern Atlantic marine biodiversity fell, but the Paris Basin and the Loire-Atlantique (Britain) still correspond to very rich areas having a mollusc richness exceeding 1000 species (Merle, 2008; 2009, Lebrun et al., 2013).

This variety is generally found in Jackson (Bartonian
) deposits and is evidence that the Texas occurrence is of equivalent age to the Moodys Branch Formation or younger deposits in the eastern Gulf of Mexico coastal plain.
The Middle Eocene (Lutetian to Bartonian
) assemblage is chararcterized by Asterigerina rotula, Sphaerogypsina globula, Austrotrillina eocenica Eorupertia spp., Pellatispira spp., and Linderina spp., Rotalia trochidoformis, Ranikothalia nutalli, Lockhartia hunti, Assilina sublaminosa, Assilina leymeriei and Assilina subspinosa.
Based on the paleontological studies the age of the Jahrum Formation is Middle Eocene (Lutetian to Bartonian
) to Late Eocene (Priabonian).
