Buda Limestone stratigraphic column in Texas. The Buda Limestone is a geological formation in the High Plains and Trans-Pecos regions of West Texas [1] and in southern New Mexico, [2] whose strata date back to the Late Cretaceous. Pterosaur remains are among the fossils that have been recovered from the formation. [3]
In Oklahoma, the light-colored limestone transitions gradually into red-colored sandstone and shale until the limestone is virtually nonexistent in north-central Texas. [5] The portion of the red beds with abundant fossil deposits is in Texas between the Red River and the Salt Fork Brazos River. [6]
The Edwards Group is a geologic group in Texas. It preserves fossils dating back to the Cretaceous period. A stratigraphic column at the Mount Bonnell Fault location starts with the Lower Cretaceous Trinity Group overlain by the Edwards Group. Upper Cretaceous formations follow, starting with the Del Rio Clay, Buda Limestone, and then the Eagle ...

The putative galloanseran bird Austinornis lentus has been found in the Austin Chalk. [2] [3] The general absence of dinosaurs is a reflection of the Austin limestone being marine in origin, primarily composed of microscopic shell fragments from floating sea organisms known as "coccolithophores" (the same organisms that contributed to the White Cliffs of Dover, on the south coast of England). [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 ...
