Texigryphaea Belvederensis

	Texigryphaea Belvederensis ''Texigryphaea'' is an extinct genus of oyster belonging to the order Ostreida and family Gryphaeidae. 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. However, specimens have been identified from northern Spain. The genus were free-living benthic oysters that were often the dominant species in late Albian biomes of the Western Interior Seaway. Some limestone beds of the Muleros Formation near El Paso, Texas, consist almost entirely of fossil fragments of ''T. washitaensis''. Most species preferred soft substrates in quiet environments, but ''T. navia'' was adapted to firmer substrates in more energetic environments. 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). ''T. tucumcarii'' is considered to be a synonym for ''T. pitcheri''. Selected species * '' Texigryphaea b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Albian The Albian is both an age of the geologic timescale and a stage in the stratigraphic column. It is the youngest or uppermost subdivision of the Early/Lower Cretaceous Epoch/ Series. Its approximate time range is 113.0 ± 1.0 Ma to 100.5 ± 0.9 Ma (million years ago). The Albian is preceded by the Aptian and followed by the Cenomanian. Stratigraphic definitions The Albian Stage was first proposed in 1842 by Alcide d'Orbigny. It was named after Alba, the Latin name for River Aube in France. A Global Boundary Stratotype Section and Point (GSSP), ratified by the IUGS in 2016, defines the base of the Albian as the first occurrence of the planktonic foraminiferan '' Microhedbergella renilaevis'' at the Col de Pré-Guittard section, Arnayon, Drôme, France. The top of the Albian Stage (the base of the Cenomanian Stage and Upper Cretaceous Series) is defined as the place where the foram species '' Rotalipora globotruncanoides'' first appears in the stratigraphic column.
