La Huérguina Formation

La Huérguina Formation is a geological formation in Cuenca Province composed of limestone layers that spread across the South Iberian Basin. The rock layers range from 60 to 100 meters thick and contain preserved remains from ancient ecosystems.

The formation originated during the Barremian stage of the Early Cretaceous period and contains fossils of dinosaurs and numerous other species from that era. The rock layers document a vanished world that once thrived in this region.

Scientists from multiple universities collaborate with the Museo de las Ciencias de Castilla-La Mancha to study the formation's paleontological treasures.

The site is located at approximately 40.0897° N and 1.8978° W and is accessible to researchers interested in exploring excavation areas with preserved fossils. Visitors should contact expert guides or research institutions to arrange safe and informative exploration.

The notable site Las Hoyas revealed Concavenator corcovatus, a theropod dinosaur with unusual neural spines that formed a distinctive hump-like structure on its back. This feature makes the species remarkable among known dinosaurs.
