When it opened I thought Essexella asherae , then it dried and I thought poorly preserved Sea Cucumber and then I thought Essexella asherae with a poorly preserved Sea Cucumber on top. Lol- that is the problem with the soft bodied fauna from Mazon Creek. It looks like a sea cucumber to me- the overall sinuous shape and web-like network of white minerals are typical. 1 Link to comment Share on other sites More sharing options...
Wrangellian Posted November 14, 2023 Share Posted November 14, 2023 9 hours ago, stats said: I've had nice looking concretions that opened cleanly and then crumbled when they dried out. There's a gray matrix from Pits 2 and 3 where this seems to commonly happen. Lost more than a few nice ones. They tend to be smaller specimens. After crumbling, they are pretty much impossible to repair. Would have probably been crushed using a hammer, so no good way to process. I'll post an example tonight. Cheers, Rich I don't mean just specimens that crumble, but those too might be explained by the same process (on a weaker/more unstable material). The good specimens that don't crumble, but split cleanly, might split because the rock shrinks slightly upon drying, just enough for the parts on either side of the plane of weakness to pull away from each other and a crack appears. In some concretions the split might already have separated enough to come apart before drying (eg. by frost action)... but I'm just hypothesizing here.

stats Posted November 15, 2023 Share Posted November 15, 2023 Here's an example of the ones that open cleanly, but crumble after drying. It a fern of some type. Cheers, Rich Link to comment Share on other sites More sharing options...
Nimravis Posted March 9 Author Share Posted March 9 A couple worms broke apart during the freeze / thaw process, that is something that can happen. This next piece opened nicely. I have all of my fossil collecting stuff put away since we are having our place remodeled. My eyes are not the greatest up close- I am thinking this looks like an Acanthodes. @RCFossils , @stats, @connorp, @Mark Kmiecik what do you guys think? 6 Link to comment Share on other sites More sharing options...
stats Posted March 9 Share Posted March 9 Acanthodes for sure. Very nice! Cheers, Rich 1 1 Link to comment Share on other sites More sharing options...

Mark Kmiecik Posted March 10 Share Posted March 10 That's a keeper. And the worms can be reassembled and still be almost as good as (300 million-year-old) new. 1 Mark. Fossil hunting is easy -- they don't run away when you shoot at them! Link to comment Share on other sites More sharing options...

Nimravis Posted March 10 Author Share Posted March 10 Here is another fish that popped open today. A weak shrimp, with one half that broke during the process. Not sure about this next piece looks like a “Blade”. 4 Link to comment Share on other sites More sharing options...

Nimravis Posted March 24 Author Share Posted March 24 A few things that popped today, nothing special, but I do like the little pyritized leaf, believe it is a Neuropteris. Misc. Plant material- Coprolite- Essexella asherae- Brachiopod ??- Worm?? 3 Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted March 24 Share Posted March 24 I dunno, but I hope it is a brachiopod. I undersatnd a lingulid is found in the Mazon Creek, but they are quite rare? Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

Nimravis Posted April 8 Author Share Posted April 8 Here are a couple pieces that popped today via Freeze / Thaw. Cyclus americanus Double Essexella asherae Mazonomya mazonensis Shrimp Molt ?? At first I was thinking a weak shrimp, but when it dried, I changed my opinion. It does have the shape of a Gilpichthys greenei, not sure. I do not have any of my loupes, but I believe these might be the jaws of Esconites zelus. And last, a nice Annularia. 6 Link to comment Share on other sites More sharing options...
bigred97 Posted April 8 Share Posted April 8 I thought Gilpichthys greenei right away. And that does look like Esconites zelus jaws. Nice! 1 Link to comment Share on other sites More sharing options...
jdp Posted April 8 Share Posted April 8 I also get Gilpichthys vibes but it would help to see the mouthparts better Link to comment Share on other sites More sharing options...
