About 11 species, see text Texigryphaea is an extinct genus of oyster belonging to the order Ostreida and family Gryphaeidae.

[3] It dates to the Albian to Cenomanian Ages of the Cretaceous period and is primarily found in Texas and the southern Western Interior of North America.

[4] The genus were free-living benthic oysters that were often the dominant species in late Albian biomes of the Western Interior Seaway.

[1] Some limestone beds of the Muleros Formation near El Paso, Texas, consist almost entirely of fossil fragments of T.

[1] The genus differs from Jurassic Gryphaeidae in possessing a vesicular shell structure and chomata (a fine set of parallel ribs found on the inner valves).
