RCFossils Posted October 6, 2018 Share Posted October 6, 2018 If you do not see hooks, there is a possibility that it could be a Priapulid. 3 Link to comment Share on other sites More sharing options...

Thanks and I agree, there is a similarity to Priapulites konecniorum , I have one somewhere in my collection and will see if I can find that one for comparison. 1 Link to comment Share on other sites More sharing options...
Rob Russell Posted October 6, 2018 Share Posted October 6, 2018 That’s pretty cool. I would have never guessed sea cucumber, and certainly don’t challenge RC’s opinion. My first reaction was a oddly preserved plant fragment. Like the edge of a fern, or something similar. Didontogaster also came to mind. I’ll be interested to know what you find under magnification, if you persue it. Anyway, Cool piece. I’m glad Rob weighed in before I embarrassed myself.

There is no embarrassing yourself here, as you know, many Mazon Creek items are often difficult to ID. 1 Link to comment Share on other sites More sharing options...

But, a shrimp was my first thought. It looks like there is segmentation and a tail. Cheers, Rich 1 Link to comment Share on other sites More sharing options...

deutscheben Posted October 8, 2018 Share Posted October 8, 2018 I have a few worms with very similar preservation to the segmented portion of the mystery fossil, but without the bulging portion. Could it be a worm with the guts squeezed out- it looks like the segmentation continues past the blob. Link to comment Share on other sites More sharing options...

Here are some pics of my finds, 95% of them will go into buckets for the May ESCONI trip to Braceville. I did find one thing that looks familiar, but for the life of me my mind is not coming up with an ID, so I am asking @RCFossils , @stats and @Rob Russell or anyone else that I forgot for their ID. This piece came out of a bucket of concretions from 1990 that I collected from Braceville. I was looking through Jack Wittry's fauna book. There are a bunch of possibilities - shrimp and worms. Jack @fiddlehead what's your opinion on this one? Cheers, Rich 1 Link to comment Share on other sites More sharing options...
Wrangellian Posted October 8, 2018 Share Posted October 8, 2018 I was going to comment on the segmentation but someone already did - that would rule out sea cucumber, correct? Interesting, whatever it is. Link to comment Share on other sites More sharing options...
Nimravis Posted October 9, 2018 Author Share Posted October 9, 2018 I decided to take today off because it was really nice outside and I figured that I could get through a number of concretions. I picked one bucket that contained a lot of "ends" and "middles" of concretions that I collected from Pit 4 (Shadow Lakes). When I use to help a friend with Braidwood Library trips to Pit 11 we would always bring a bunch of concretions like this to open in front of the group. Concretions like this have an almost 100 % chance of containing some type of fossil. I separated four groups and took pictures of what was found inside. No fauna was found and the majority of the flora was Lycopod leaves, but bark and ferns were also found. Nothing great was found in these ends today, but kids use to love to open the concretion after we split them and the lucky kid was the first person to ever see that fossil. With the exception of 2 or 3 fossils, the rest went into a bucket for the May ESCONI trip to the Braceville Shaft mine- I now have 2 5-Gallon buckets full for that trip.

Nimravis Posted October 9, 2018 Author Share Posted October 9, 2018 I then open a lot of concretions from the area I call "Across From Pit 4" and I had terrible luck and the fossils I did find I just threw into a bucket to give away. One halve that I did find open in the bucket was a poorly preserved Cuclus americanus and a Myalinella meeki Bivalve. Here are some very nicely shaped concretions that I separated out, I will put those off to the side to Freeze / Thaw. Here is my favorite find from the day, I believe it is a Neuropteris, but I am going to ask Jack @fiddlehead for the correct identification. This one would have been nice to Freeze / Thaw, but I can't do it to all of my concretions. 3 Link to comment Share on other sites More sharing options...

Cheers, Rich At first I was thing that it was, but the problem that I have with Cyclopteris, is that it does not have the general shape of Cyclopteris that I have found before, and was thinking that it was the terminal leaf of some type of Neuropteris. 1 Link to comment Share on other sites More sharing options...

Nimravis Posted October 11, 2018 Author Share Posted October 11, 2018 I did not have much time to open concretions before it got dark, but I did find a couple nice things. The majority of the stuff that I found went into a bucket to hand out at trips, but heare are a couple nicer pieces. I believe that this is a nice Mariopteris. A couple nice Macroneuropteris. And lastly, a couple pieces of Coprolite, the first one is very nice. 5 Link to comment Share on other sites More sharing options...
Nimravis Posted October 12, 2018 Author Share Posted October 12, 2018 Today I only had time to open about 20 concretions before the sun set and with the temp being 44 degrees, it got difficult to hold the concretions while trying to strike them. I was opening concretions that I collected from the Braceville Shaft Mine from 6-1998, her are my finds from today.

Nimravis Posted October 12, 2018 Author Share Posted October 12, 2018 Tonight I had a terrible time trying to find a fossil in the 70+ concretions that I opened tonight. Here are the 5 fossils that I found and nothing great at all. Myalinella meeki- Coprolite- Bark- 1 Link to comment Share on other sites More sharing options...
