Las Hoyas was an inland lacustrine environment which presents an important aquatic and terrestrial flora (with many specimens of Charophytes, Montsechia, Weischelia or Frenelopsis) and diverse fauna, with specimens of at least five or six Phyla: Arthropods, Molluscs, Chordata and many vermiform soft bodied animals which might be Nemertines or Annelids.

If the Dené–Caucasian hypothesis, which attempts to link Basque, Burushaski, the North Caucasian families and other phyla, is correct, then the similarities to Basque may also be due to these influences, however indirect.
