Mazon Creek Finds - Tully?

[Patrick K.]

Hello all! 
 

 I’ve had the chance to get out a few times this year, collecting has been good! So far 3 trips, my daughter has a Tully, a friend found a half of one (hopefully posts it!) and we’ve had numerous random open fossils of various species. And LOTS of full concretions to freeze-thaw open.

 Here’s a few I was hoping to get confirmation on - I found some good clues  in Jack Wittry’s book. 

 

1) My daughter’s Tully - found open, covered in mineral deposits. 

 

2) A large shrimp - weathered and probably open for a long time 

 

3) Maybe an Orbiculoidea sp.? Pretty weathered but looks close to the books

 

Lastly maybe an indeterminate discoidal cephalopod? I only have half of the fossil but it’s quite a deep concretion & shell shaped.

Thanks for stopping by!

 

Pat

Not so sure on Orbiculoidea but I agree with your other IDs. Nice Tully.

Tully body and eye bar. No front or rear end. Definitely Tully, though. Nice find. Over 20 years of collecting and I never found one. The shrimp looks like Belotelson magister. Orbiculoidea is a possibility, but a long shot. The last one may be a poorly preserved Cyclopteris pinnule or a Macroneuropteris basal pinnule. They often are preserved on a "pedestal". See attached photo.

Thanks for the replies and info, I do appreciate it! 

 

 That's a bit of a bummer Mark! On the other hand, you have a wonderful and diverse collection. While I don't have one myself, we have been really lucky this year. Here's my buddy's Tully he found with me last Sunday, it needs a bit of light cleaning still but its a great find - only one half. Hopefully he chimes in w some finds from last weekend here -
