connorp Posted January 16, 2020 Share Posted January 16, 2020 I had a few duds pop open yesterday but saw one had a tiny speck of something on it, no more than a millimeter long. I had my digital microscope out for other microfossiling activities and decided to take a look. Nothing super interesting, just a tiny plant fragment. But it did get me curious if anyone has done micropaleontology work on Mazon Creek material? I would think there would be quite a bit to explore, but that said I've never really seen the topic mentioned. The only microfossil I've seen discussed from Mazon Creek is a species of ostracod, but usually the only specimens you see are nodules containing hundreds of ostracods as they are readily apparent to the naked eye in that case. 3 Link to comment Share on other sites More sharing options...
Nimravis Posted January 16, 2020 Share Posted January 16, 2020 I could see some tiny stuff being preserved in concretions that gets overlooked, I never look that close. Link to comment Share on other sites More sharing options...

I use a loop, but i had to see it pretty good to start with. I like to look closely at coprolites, because sometimes you can see animal parts, fish scales, etc. Cheers, Rich 1 Link to comment Share on other sites More sharing options...
TheRocksWillShoutHisGlory Posted January 16, 2020 Share Posted January 16, 2020 I've only ever looked for more detail on an already visible fossil. I know microscopic analysis of eye pigment was done in the 2016 tully monster study. Here's a structure I thought was curious in a fish. I've sent it to a few professionals because I thought it could be a heart valve. I also have a picture of shrimp antennae, and clam shell material I'll post later. 2 Link to comment Share on other sites More sharing options...

digit Posted January 17, 2020 Share Posted January 17, 2020 Wow! As usual, these Mazon Creek concretions are highly enigmatic and very much Rorschach inkblot tests in sideride form. Do you know what species of fish is represented in the concretion above? I cannot even make out anything fishlike in that concretion. Cheers. -Ken 1 Link to comment Share on other sites More sharing options...

TheRocksWillShoutHisGlory Posted January 18, 2020 Share Posted January 18, 2020 This is the shrimp antenna, any interpretation what the circles along it are? Link to comment Share on other sites More sharing options...
