Success!
A nagging problem we have had is that we haven’t been able to figure out which layer in this broad locality is the productive layer for fossils. Fossils can be found all over on the surface, but they are almost always broken up and spread out due to processes of weathering.
It would be nice to know where the fossils are coming from so that we can collect complete, pristine specimens, rather than bagging up bits of bones that we hope all go together.
Today, we finally pinned it down. Though vertebrate fossils may be found anywhere in the rocks, they are concentrated on the surface between the greenish beds and the reddish beds.
In some places there’s little pebbles and sandstone on this contact. Now all we need to do is figure out what that means.
We’ll be going back tomorrow!
