Upper Paleolithic humans may have hunted cave lions for their pelts, perhaps contributing to their extinction, according to a new study.
Considered ‘biodiversity reservoirs,’ most underwater caves are yet to be explored. Furthermore, species diversity and distributional data is currently scattered enough to seriously hinder conservation status assessments. Thereby, a large international…
Stalagmites rising from the floor of a cave in southern Indiana may contain traces of past earthquakes in the region, according to a new report.
When mineral-rich water drips from a cave’s ceiling over centuries and millennia, it forms rocky cones that hold clues to the Earth’s past climate. Now, researchers in Australia and the UK have found that these structures can also help trace past wildf…
Environmental records obtained from archaeological sites in South Africa’s southern Cape suggest climate may not have been directly linked to cultural and technological innovations of Middle Stone Age humans in southern Africa after all.

Scientists roped in the use of high-tech laser scanning, photogrammetry and 3-D mapping technology to map Homo naledi’s Dinaledi chamber.
The Mäanderhöhle cave near Bamberg was previously regarded as an archaeological sensation. It was thought to contain some of the oldest cave art in Germany. However, a researcher has demonstrated that the markings discovered inside the cave in 2005 are not fertility symbols carved by humans as previously thought. In fact, these lines occurred as a result of natural processes, the archaeologist says.
A widespread and permanent loss of forests in Madagascar that occurred 1,000 years ago was due not to climate change or any natural disaster, but to human settlers who set fire to the forests to make way for grazing cattle, suggests researchers.
When carbon dioxide is stored underground in a process known as geological sequestration, it can find multiple escape pathways due to chemical reactions between carbon dioxide, water, rocks and cement from abandoned wells, according to researchers.
Australia’s Nullarbor Plain is one of the driest landscapes in the country, but new research suggests it was once forest that received up to four times as much rain as it gets now.
While most of the knowledge about tiny snails comes from studying deserted shells sifted out from piles of dust and sand, the present research is the first contemporary microscopic exploration of organs in cave snails tinier than 2 mm. The paper reveal…
