Man known as "Hombre del Sidron" (human fossils found in a caved called "Sidron" in 1994) could be identified with "Homo Neandertalensis" typical features, a specie within homo gender and contemporary man ancestor. "Homo Neandertalensis" appeared in Europe 230.000 years ago, and become extinct 35.000 years ago. "Sidron" man features let us know that we are facing one of the most primitive kind of homo, within "Homo Neandertalensis". But we have also to take into account that scientists have not show us the clue to support this theory, due to several enigmas related to this important discovery.

      Despite of this fact, we should be very proud of this site, because it is the most important prehistoric discovery in Asturias. It has been also compared to Atapuercas's site, although last details should be confirmed.
      There are no human remain found in Asturias before "Sidron" ones (just "Homo Sapiens" remains found in "La Cueva de los Azules" in Cangas de Onis).
      Scientists have noticed "Homo Heildelbergensis" features ("Homo Neandertalensis" inmediate ancestor) in fossils discovered in "Sidron" site, and they could be 200.000 years old, so it is a very important site.
      Fossils found (belonging to jaws and teeth) have appeared inside the cave but they are not displayed in a typical burial, they were on the surface. We would like to mention a big bone (belonging to an arm) which let us know these first settlers were really strong and sturdy.
      There is also a stone tool industry related to these human remains (26 silex remains made in "Musteriensis" technique) and directly connected with "Homo Neandertalensis".
      On the other hand, "Sidron" cave has been always an interesting place for geological studies, due to it is location (it is the largest cave all over the region).
