The entrance lies at the top west side of the large slip feature to the east of Cueva de Coberruyo (138). A 3m rope climb drops into a 5m diameter chamber.

The cave has been excavated and is described as a late Bronze Age burial cave: bones have been found from at least 5 individuals (1 adult and 4 children) and some of these were deliberately fractured. A human bone has been dated to 870BC and wood to >41760 years - the limit of carbon dating. Remains below the modern surface include sheep, goat, wild boar, red deer, hen, snail shells, nuts, mussel shells and dog oyster. Only one piece of pottery was found and no grave goods.
Ruiz Cobo Jesús and Smith Peter et al, 2001: The Archaeology of the Matienzo Depression, North Spain and Castaños Pedro, 2001b: Estudio de la fauna de la Sima del Diente detail the excavations, results and conclusions.
A useful summary is to be found in Ruiz Cobo Jesús and Smith Peter, 2003, pages 57-63, with a survey, photos and diagrams. Other photos and tables are scattered through the publication.
