The Black Peaks Formation is a geological formation in Texas whose strata date back to the Late Cretaceous. Dinosaur remains (from the sauropod Alamosaurus) have been among the fossils reported from the formation.[1][2] The boundary with the underlying Javelina Formation has been estimated at about 66.5 million years old.[3] The formation preserves the rays Rhombodus and Dasyatis, as well as many gar scales.[4]
