The occasional fossil

oh why wait
I was rooting around the net and found this:



It's a 125 million year old cicada from china. Click on the image to make it bigger, it's worth it I promise. You can see the segmentation of the body and the veins in the wings. That level of preservation is remarkable. I don't know for sure but this was probably preserved in a lake. A lot of the material coming from China is from ancient lakes. Because they usually have very fine sediments and not a lot of water movement lakes are ideal environments for preserving fine detail.
