The Tlayúa Formation is an Early Cretaceous (late Albian) geological formation near Tepexi de Rodríguez, Puebla.[1]
Paleobiota
[edit]The formation contains a diverse array of vertebrate and invertebrate fossils. About 70% of the macrofossils are osteichthyan fish.[2] Other vertebrates include chelonians, pterosaurs, lepidosaurs, and crocodiles.[3] Cyanobacteria, foraminifera, algae, gymnosperms, sponges, cnidarians, annelids, gastropods, ammonites, bivalves, arachnids, insects, isopods, anomurans, brachyurans, crinoids, echinoids, holothuroids, stelleroids, and ophiuroids, have also been recovered from the Tlayúa Formation.[3][4][5]
Lepidosaurs
[edit]| Genus | Species | Abundance | Notes |
|---|---|---|---|
| Huehuecuetzpalli | H. mixtecus | A primitive lizard | |
| Pamizinsaurus | P. tlayuaensis | An osteoderm-covered sphenodontian | |
| Ankylosphenodon[6] | A. pachyostosus | An aquatic sphenodontian | |
| Tepexisaurus[7] | T. tepexii | A basal scincomorph |
