Rockwood Posted January 6, 2018 Share Posted January 6, 2018 I found these while doing some prep. on fish in a Brazilian concretion. They have to be seed shrimp. Right ? Link to comment Share on other sites More sharing options...
Fossildude19 Posted January 6, 2018 Share Posted January 6, 2018 They look like they might be. Some papers here.

Al Dente Posted January 6, 2018 Share Posted January 6, 2018 Can you see two valves with one overlapping the other? If not they might be little phosphate pellets. 1 Link to comment Share on other sites More sharing options...

JohnBrewer Posted January 6, 2018 Share Posted January 6, 2018 Hmmm not sure. Maybe a little prep may help John Map of UK fossil sites Link to comment Share on other sites More sharing options...

They seem to, especially on the shinier one. It's like a single waved line. Link to comment Share on other sites More sharing options...
Fossildude19 Posted January 6, 2018 Share Posted January 6, 2018 The one on the top, in the middle, looks like it might have both valves.

It's the only one I actually extracted. The others are likely steinkerns. I found them in the chips. 1 Link to comment Share on other sites More sharing options...

gturner333 Posted January 9, 2018 Share Posted January 9, 2018 Without a really good closeup, they look very much like ostracods to me. Any idea what formation or period these came from? I find a lot of ostracods in Carboniferous Period matrix. Link to comment Share on other sites More sharing options...
doushantuo Posted January 9, 2018 Share Posted January 9, 2018 Might be . Possibly cytherellids. "Brazilian concretion" might imply Pattersoncypris I'm more used to seeing SEMs of ostracods,so I'm possibly not the best one to judge Link to comment Share on other sites More sharing options...

A binocular scope may be one of the things I have to pack with me when I retire to a warmer more fossiliferous climate, but SEM not so likely.
