Mazon Creek - More Pit 11 (Already Opened Concretions)

[evannorton]

Hi Folks-

Here are some more already opened concretions from a recent Pit 11 trip.

Let me know if you disagree with any of my IDs.

1) Priapulites konecrniorum

2) Partial Tully (poor preservation)

3) Unknown

4) shrimp molt

5) Pieckonia helenae

I cannot make out much detail on #1 but I am pretty certain it is not priapulites. My guess is either a trail or possibly a poorly preserved Fossundecima. I would agree that #2 might be a piece of a Tully but it may also just be the way the concretion weathered once split. I think # 3 is just mineralization. I agree with the shrimp molt. I believe #5 is a partial coprinoscolex.

Definately a promising start.
