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
