A Neanderthal's specialised burning structure compatible with tar obtention

Here we present multiproxy evidence of a new type of Neanderthal hearth discovered in Vanguard Cave (VC) (Gibraltar), which is dated ∼ 65 kyr, and ass…

So I started with 3g of sediment and this is what I have left after an acid bath in HCl to get rid of carbonates, separating out the clays, baking the organics out at 500 degrees C and separating out the silica 😳 But it’s ok! Gonna have lots of microfossils to look at! #phytoliths #sponges #diatoms #microfossils #PalaeoenvironmentalReconstruction #Science

Ancient stone tools from China provide earliest evidence of rice harvesting

A new Dartmouth College-led study analyzing stone tools from southern China provides the earliest evidence of rice harvesting, dating to as early as 10,000 years ago. The researchers identified two methods of harvesting rice, which helped initiate rice domestication. The results are published in PLOS ONE.
