Rosemary Posted June 18, 2019 Share Posted June 18, 2019 I was wondering if the lower left white pieces with the straight row of circles are bryozoa. Secondly, I was wondering if the seemingly silver "rod" is animal or mineral. These samples are quite small and this is the best I can do as far as focus goes.

abyssunder Posted June 18, 2019 Share Posted June 18, 2019 You may be right about the bryozoans. The straight rod is not clear for me, but you have there crinoid columnals at the top of it, if I'm not wrong.

Rockwood Posted June 19, 2019 Share Posted June 19, 2019 Could the silver thing be a fin spine from a fish ? Link to comment Share on other sites More sharing options...
ClearLake Posted June 19, 2019 Share Posted June 19, 2019 You say "quite small", but is that silver thing just a few mm's long? It could be a piece of a brachiopod spine also. May be hard to ID without some more detail such as size, what the cross section looks like, etc. Always interesting to zoom way in on this fossiliferous rock!

Rosemary Posted June 19, 2019 Author Share Posted June 19, 2019 If this is the same thing, here is a broken piece. And, yes, they are a matter of 2 or 3mm. Very narrow. Not even a mm. Link to comment Share on other sites More sharing options...

TqB Posted June 19, 2019 Share Posted June 19, 2019 Of the ones I've seen, brachiopod spines often look silvery like that while crinoid spines don't. Presumably that's down to their different crystal structures. 1 Tarquin Link to comment Share on other sites More sharing options...
