I've seen some articles (CogniArchae.com, Facebook, X.com) featuring what appears to be a serpent-like entity allegedly depicted on a wall in the Altamira caves, as below: Yet I haven't found any official sounding catalogue numbers assigned to it, nor does it appear here: https://www.ancientartarchive.org/altamira-cave-spain/ That may not be the definitive end-all-be-all, but it is enough to concern me that it's not real. Is it authentic, and, if so, what is its proper catalogue number?
