Lower Palaeolithic quarry site northwest of Budapest, Hungary, near the confluence of the Ataler and Danube rivers, with artifacts and fauna dating 350,000-175,000 bp (Middle Pleistocene). The pebble chopping tools and flake tools are associated with human skeletal remains which are intermediate between Homo erectus and Homo sapiens (Homo (erectus seu sapiens) palaeohungaricus). The principal significance of this specimen, apart from its structure, is that it is dated to a warm phase within the second (Mindel) glaciation, 500,000 to 400,000 years ago.
