Where is a place that has both Lano Estacado and Buda Limestone geological formations?
Buda Limestone The Buda Limestone is a geological formation in the High Plains and Trans-Pecos regions of West Texas whose strata date back to the Late Cretaceous. Pterosaur remains are among the fossils that have been recovered from the formation.
La Negra Formation La Negra Formation (Spanish: "Formación La Negra" ) is a geologic formation of Jurassic age, composed chiefly of volcanic and volcaniclastic rocks, located in the Coast Range of northern Chile. The formation originated in marine and continental (terrestrial) conditions, and bears evidence of submarine volcanism as well as large explosive eruptions. The volcanism of La Negra Formation is thought to have lasted for about five million years.
