The site is an outcrop of sedimentary rock from a 49 million year old lake. The site seems to be from a fairly deep area of the lake. This means a large portion of the rock is shale with some sandstone layers interspersed. The shale is composed in a large by very fine volcanic ash, making for exceptional preservation. we also have one or two layers which are probably composed of fine diatoms.

Can you put together some of this interesting information and submit it to the forums? It doesn't have to be a full fledged article (alhough that would be nice, too). It would be very instructive. For instance, I thought that practically all fossil insects were specimens in amber, I didn't know about this site.

I could probably put together information for the forums, what do you think I should include? Age, palaeoenviroment, climate, preservation causes, flora (briefly), fauna (detailed insect, general other)?

Honestly, it is entirely up to you. Do as little or as much as you want. Do it in installments if you feel like it. Thanks for anything you do.

for the information. I am currently reading the Grimaldi and Engel book and this melds nicely with that reading!
