Tlayua quarry (Cretaceous to of Mexico)

Where: Puebla, Mexico (18.6° N, 97.9° W: paleocoordinates 16.6° N, 63.1° W)

• coordinate based on political unit

• small collection-level geographic resolution

When: Middle Member (Tlayua Formation), Middle Albian to Middle Albian (109.0 - 99.6 Ma)

• Time interval based on ammonoid and belemnoid evidence.

• member-level stratigraphic resolution

Environment/lithology: lagoonal or restricted shallow subtidal; red lime mudstone

• Environment based on Espinosa-Arrubarrena and Applegate (1996). "The strata were deposited in the Tlayua lagoon, a back lagoon with a lethal bottom, which was separate from a bio-rich lagoon by a barrier. Some rivers lowed into the Tlayua lagoon from the continental arid land located at the west; to the east, the bio-rich lagoon was surrounded by a coral reef connected to the Tethys Sea.

Size class: macrofossils

Preservation: adpression

Collected by Aranguthy family and their Tlayua quarry workers
