The Woodbine Group is a geological formation in east Texas whose strata date back to the Early to Middle Cenomanian age of the Late Cretaceous.[1] It is the producing formation of the giant East Texas Oil Field (also known as the "Black Giant") from which over 5.42 billion barrels of oil have been produced.[3] The Woodbine overlies the Maness Shale, Buda Limestone, or older rocks, and underlies the Eagle Ford Group or Austin Chalk. In outcrop the Woodbine Group has been subdivided into the Lewisville Sandstone, Dexter Sandstone, and/or Pepper Shale formations.[1] Thin-bedded sands of the Woodbine and Eagle Ford are collectively referred to as the "Eaglebine" oil and gas play in the southwestern portion of the East Texas region.[4]

Dinosaur and crocodilian remains are among the fossils that have been recovered from the formation.[5] This fossil formation preserves organisms that were endemic to Appalachia.[6]
The Woodbine Group was first mapped and named by Robert T. Hill, known as the "Father of Texas Geology", for outcrops near the small town of Woodbine, Texas in 1901.[2] The Woodbine represents ancient river and delta systems that originated from erosion of the Ouachita Uplift in modern-day Oklahoma and Arkansas and the Sabine Uplift in modern-day Texas and Louisiana. Sediments from these deltas flowed into the East Texas and Brazos Basins of the ancient East Texas shelf.[7]
The Arlington Archosaur Site is a location in Arlington, Texas that currently excavates fossils from the Woodbine Group. It became available to access by the University of Texas at Arlington (UTA) in spring of 2008. UTA and the Dallas Paleontological Society have excavated at the site up to present day, where work continues.[8]
