Which human relatives are associated with the Mousterian tool culture in the Low Countries?

The Mousterian tool culture in the Low Countries, dating from approximately 80,000 to 35,000 years ago, is associated with Neanderthals.1

Evidence of this industry has been documented in the Ardennes caves of southern Belgium and at open excavation sites in the Netherlands' North Brabant province and the Belgian Limburg region. Skeletal remains of Neanderthals, which confirm their presence in the broader region, were discovered in the 19th century at sites such as Spy and Engis in Belgium.1
