The Noisetier Cave (French: Grotte du Noisetier, lit: Hazel cave, also Grotte de Peyrère or Grotte de Serrat de la Toue), owing its popular name to the Hazel trees that grow in front of its entrance, is located in a mountainside 145 m (476 ft) atop the Vallée d'Aure in the Ardengost commune, Hautes-Pyrénées department in the region Occitania, Southern France. During systematic excavations since 1992 Middle Paleolithic stone tools and artifacts attributed to the Neanderthal Mousterian culture were discovered among numerous faunal remains.

The site has delivered three dental relics. According to morphological and metric traits, these teeth fit in the variability of Neanderthal. The teeth have a significant attrition of the crown and incomplete roots as those of a 5 to 10-year-old child. Depending on the current variability and the fact that they have been discovered in the same sector and in the same level, they could correspond to the same individual.
