Nimravis Posted July 28, 2022 Author Share Posted July 28, 2022 This evening I whacked open a bunch of concretions, here are my finds. An okay Macroneuropteris A cute Annularia A nice Pecopteris A couple little pieces of fertile ferns. A little Neuropteris pinnule What appears to be a piece of coprolite or a weathered seed, though I am leaning towards coprolite. Some misc pieces of flora- bark, lycopod leave pieces, ferns. 5 Link to comment Share on other sites More sharing options...

So how does it feel going back to whacking after so much unbanding? Fossils? I dig it. Link to comment Share on other sites More sharing options...

Nimravis Posted July 30, 2022 Author Share Posted July 30, 2022 (edited) Here are some items that I whacked open today- a little bit of everything: Annularia, Pecopteris, Sphenophyllum, Alethopteris, Cyperites, bark, etc. Edited July 30, 2022 by Nimravis 4 Link to comment Share on other sites More sharing options...

Nimravis Posted July 31, 2022 Author Share Posted July 31, 2022 Well I spent about 1 hour whacking open more concretions that I recently collected. Today was the day of the Alethopteris, I usually do not find many and they are in my top 3 of the flora that I collect. These pieces were not complete, but it was still nice coming across some. A okay looking Pecopteris, hopefully it will clean up nicely. Here is a nice fertile Pecopteris. Here are some misc pieces of ferns and bark. Here is a big piece that opened in 2 whacks. It contains some bark and a fern. This piece as well as most of the recent pieces that I broke open, will end up in the buckets of fossils, that will be dumped at the next ESCONI Braceville fossil trip. 3 Link to comment Share on other sites More sharing options...
Nimravis Posted August 15, 2022 Author Share Posted August 15, 2022 I had my 8 year old grandson for the past week and besides playing football, baseball, going to the movies, climbing, spending a couple days in Springfield at the State Fair, I also took him fossil collecting for the first time. Here are a couple pics of his first fossil finds. A couple Pecopteris. Here is a larger Pecopteris that I tapped once and it opened. After getting back from the State Fair today, I decided to whack open some concretions, all Flora. A quick look at these after popping them open and they all appear to be Pecopteris. Here is my favorite, followed by the others. Macroneuropteris- Annularia- Asterophyllites equisetiformis- A partial Cyclopteris, that would have been real nice, if complete. Alethopteris- I believe that this is Sigillaria- Cleaned up- Cyperites- 7 Link to comment Share on other sites More sharing options...
Nimravis Posted August 15, 2022 Author Share Posted August 15, 2022 Calamites- A nice limb portion- Lepidostrobophylkum majus- These concretions it took a number of whacks at, but decided to stop and I will freeze / thaw them. 5 Link to comment Share on other sites More sharing options...
Nimravis Posted August 18, 2022 Author Share Posted August 18, 2022 (edited) Here are my finds from today- Pecopteris- Neuropteris- Cyclopteris- My favorite from today. Cyperites- Lepidostrobophyllum majus- Annularia- And glued- Coprolite- Bark / Stems- Some concretions look fractured like the one below and you just have to whack it and put it back together.

Nimravis Posted August 19, 2022 Author Share Posted August 19, 2022 One thing that amazes me is the mathematical perfection in nature as it relates to many Mazon Creek Flora pieces. Here are 2 examples, one that I opened yesterday and another that I opened in the field, about a week ago. This piece yesterday split perfectly, with only one tap. The piece is exactly 2 1/4” wide and the mid vein of the fossil is located at the dead center point, 1 1/8”. This next piece that I opened in the field is 2 3/8” wide and again, the mid vein is located dead center at 1 3/16”. I never checked with fauna pieces, but I bet that there are many that this would apply too. 2 Link to comment Share on other sites More sharing options...

The chemical halo that surrounded the decaying organic matter must have been symmetrical. That probably means the mud, which turned to shale, was isotropic and homogeneous. The oblong lumpy ones were formed in conditions that probably had more variation. There are some papers that examine concretion formation. I don't remember them addressing your observation.

Nimravis Posted August 24, 2022 Author Share Posted August 24, 2022 I started to whack open concretions that were not complete. These concretions and the ones shown in recent posts on this thread are from recent collecting trips. Today I found a bunch of stuff that I considered very low grade, but good for beginners, so these pieces will end up in buckets for an upcoming ESCONI trip. Hopefully the finds will improve. 5 Link to comment Share on other sites More sharing options...

When I first started collecting (Ages ago, by which I mean about 4 months ago...) - I never understood giving away/throwing away fossils... Oh how things have changed - I've had to stop picking up teeth that aren't complete. Fossils? I dig it. Link to comment Share on other sites More sharing options...

Nimravis Posted August 27, 2022 Author Share Posted August 27, 2022 (edited) I just finished whacking open a number of partial concretions. The nice thing about todays session was that fact that 95% of the concretions that I opened had fossils. I am leaving the complete concretions that I recently found and I am concentrating on the partial pieces. Today I came across bark, including Calamites. Neuropteris, Pecopteris, Annularia, Cyperites, Asterophyllites, Alethopteris. Here they are in the order that I cracked them open.
