translate English to French: But the most beautiful caves are Raj (Paradise) in the Swietokrzyskie Range and Niedzwiedzia (Bear) in the Sudetan Mountains. In both, you can admire the unearthed bones of Pleistocene animals - mammoth, woolly rhinoceros, bear and cave lion, and also bone tools - the work of Neanderthal man living 40-50 thousand years ago.
On y trouve les ossements d'animaux provenant du pliocene ainsi que des outils fabriqués par l'homme de Néanderthal, datant de 40 a 50 000 ans.
