Black Peaks
Description
Source: Wikipédia
The Black Peaks Formation is a geological formation in Texas whose strata date back to the Late Cretaceous. Though some of its strata date back to the Paleocene and Eocene. Dinosaur remains (from a titanosaurian sauropod, either Alamosaurus or Utetitan, and a tyrannosaurid) and the pterosaur Quetzalcoatlus northropi are among the fossils reported from the formation. The boundary with the underlying Javelina Formation has been estimated at 66.5 million years old. The formation preserves the rays Rhombodus and Dasyatis, as well as many gar scales. Cenozoic aged fossils unearthed here consist of mammals like multituberculates, barylambdids, and insectivores, as well as alligatorids like Bottosaurus. Turtle fossils have also been unearthed here too.
