The excavations showed that the presence of humans can be proven in almost all layers. Also proven are, among other things: Cave bear, cave lion, cave hyena, wolf, arctic and red fox. The rich small fauna, together with plant remains such as charcoal, pollen and the analysis of the sediments, provide good insights into the climate development during the deposition period. In this way, the mighty sequence of layers becomes a multi-structured archive that documents the constant change in climate and environmental conditions during the Ice Age over a long period of time. The thick lower layer package shows temperate to warm-temperate conditions with some climate variability. At that time, Barbary macaques lived in the Franconian Alb, which was covered by sparse mixed forest. The climate archive also shows that this phase came to an end and it became increasingly drier and colder. The northern vole, the pygmy pika, the lemming and other cold-tolerant animal species spread as a result. Rewarming began with the top layers.
In 2002, a sinter blanket was found at the base of the layer sequence in the new excavation area. One study found a time window of about 100,000 to 125,000 years in the range of 200,000 years. This would allow the entire sediment sequence to be dated to the beginning of the Würm Ice Age. The stone artifacts found in the upper layers are consistent with the archaeologists' dating. The devices from the lower layers differ significantly from the younger ones and can be compared with Middle Pleistocene sites. The new dating makes the 1986 discovery of a human molar from Hunas a classic Neanderthal and therefore the oldest hominid from Bavaria.
