daves64 Posted January 24, 2020 Share Posted January 24, 2020 I recently purchased some Mid Devonian silica shale pieces with trilo-bits from @connorp. And by recently I mean last month... last year..(January is always confusing that way). Just several small pieces with partial molts I'm using for practice prepping. So after picking at a few all year... one of them has gone from a practice piece to an almost show piece. 1st pic is the original sales pic with the piece circled. In it you can see part of the trilo-bit, but not really anything else. I got a nose w/ a partial eye (base only), bryozoa scattered about here & there, some tiny crinoid pieces and a thing I can't decide on. Pic labeled with a 1 is an overall shot, 2 is a close up of the nose, 3 is a bryozoa (I think) & 4 is the question one. The entire stone is 7.5 cm x 6.5 cm. Nose is 1 cm wide, the small bryozoa fan thingy is 0.5 cm wide & the question one is 2.5 cm long. I'm using a needle in a pin vise, fine scribe tip in another pin vise, dental picks & a stiff(ish) nylon brush with hydrogen peroxide, 3x led magnifying lamp & 10x loupe. 3 Accomplishing the impossible means only that the boss will add it to your regular duties.

Northern Sharks Posted January 24, 2020 Share Posted January 24, 2020 My first reaction is that your mystery specimen is the coral Aulopora 4 There's no limit to what you can accomplish when you're supposed to be doing something else Link to comment Share on other sites More sharing options...
FossilNerd Posted January 24, 2020 Share Posted January 24, 2020 I think Aulopora seems like a reasonable assumption for picture 4. Do you happen to know what formation it came out of? That may help to confirm or deny. BTW... looks like your prep is coming along nicely. Good job! 2 The good thing about science is that it's true whether or not you believe in it. -Neil deGrasse Tyson Everyone you will ever meet knows something you don't. -Bill Nye (The Science Guy) Link to comment Share on other sites More sharing options...

It's from the Silica Shale which is Givetian stage of the Devonian. Definitely agree that it is an Auloporoid of some sort. 2 -Dave __________________________________________________ Geologists on the whole are inconsistent drivers.

daves64 Posted January 24, 2020 Author Share Posted January 24, 2020 So the question thing is a coral... huh. I was entertaining the thought that it might be a holdfast, but coral works. Just never actually seen a smooth looking coral before. Accomplishing the impossible means only that the boss will add it to your regular duties.

Just never actually seen a smooth looking coral before. I thought maybe holdfast as well at first glance, but I don’t see a central “stump” and areas such as the ones I marked below seem to be corallites.
