| 实物特征: | Remains of selachians have been collected at the Gabinarraca cave. These fossils were found in grainstone type lithoacies from the Upper Miocene carbonated lagoon and estuarine sediments of Venado Formation. Among the sharks remains are notorious the juvenile specimens of Carcharocles megalodon associated to a shallow marine and brackish waters environments.
