Why did the palaeanthropologists go to Masol?
Masol has historically given anthropologists and geologists many pieces in the evolutionary puzzle. Experts have been drawn to the area since Sivapithecus—apes from two million years ago—were found in the Shivaliks in the 19th century.
How did they date the material found at the sites?
Multiple methods were used, including stratigraphy (assessing age through association with geological deposits or formations). Identifying layers of rock dating back to different periods is what helps to date the materials found embedded in them.
How and when did the discovery happen?
There wasn’t one discovery but many. Besides three bones with cut marks, the tools used on them were found from the rock layer of the same age. The first stone tool found in a rock layer in 2008 dated older than 2.58 million years.
