Aguja formation

The Aguja Formation is a Late Cretaceous geological formation in West Texas, primarily exposed in the Big Bend National Park region. It dates to the Campanian stage (approximately 80–72 million years ago) and consists of fluvial, coastal, and deltaic deposits. The formation preserves a diverse fossil record, including dinosaurs such as hadrosaurs, ceratopsians, pachycephalosaurs, tyrannosaurs, and dromaeosaurs, as well as turtles, crocodilians, and early mammals. The Aguja Formation provides important insights into the ecosystems of North America during the Late Cretaceous, showing a rich and varied landscape of rivers, floodplains, and coastal environments.
