fifbrindacier Posted September 18, 2017 Share Posted September 18, 2017 Hi everybody, last week i found some corals and i need your help to try to identify them because i'm no expert at all. For those who can't visualize the tags like me, it is the cenomanian from south-west of France. Thanks in advance. 1) "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux."

fifbrindacier Posted September 19, 2017 Author Share Posted September 19, 2017 It's mineral, because it's very hard. "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux."

abyssunder Posted September 19, 2017 Share Posted September 19, 2017 Are you sure that those greenish parts are not green algae(or similar) covering yellowish calcite after aragonite in the replacement process? Nice finds, BTW. " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.

fifbrindacier Posted September 20, 2017 Author Share Posted September 20, 2017 I tried to scratch them off but they didn't move, i i'll try with my engraver.

abyssunder Posted September 20, 2017 Share Posted September 20, 2017 Stop! Don't do that! Those are minerals.

fifbrindacier Posted September 20, 2017 Author Share Posted September 20, 2017 Ok, so i'll let them. I don't know very much about mineralization.

Coco Posted September 21, 2017 Share Posted September 21, 2017 H Are you able to do a very well close-up on these minerals to permit us to identify them ?

abyssunder Posted September 23, 2017 Share Posted September 23, 2017 Chip off an isolated little grain and take it in 9 degrees vinegar. If it fizzes it's calcite.

fifbrindacier Posted September 23, 2017 Author Share Posted September 23, 2017 It doesn't fizz. "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux."

HansTheLoser Posted September 25, 2017 Share Posted September 25, 2017 Poorly preserved. Probably Astraeofungia or Dimorphastrea. Some specimen seems to be moulds. Link to comment Share on other sites More sharing options...
Coco Posted September 25, 2017 Share Posted September 25, 2017 Hi, I can't distinguish the crystalline shape. What do you see ? Cube ? Rhomboedre ? Other shape ?

Other shape ? Coco I took more pics with a magnifier, i hope they'll be clear enough. I see little grains and to me it looks rhomboide. Maybe it is aragonite as suggested @abyssunder.

I looked on that site : http://www.corallosphere.org/taxon/478 and i think that the first item is a good candidate for Dimorphastrea.

abyssunder Posted September 25, 2017 Share Posted September 25, 2017 I suggested calcite, not aragonite. picture from here " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.

fifbrindacier Posted September 25, 2017 Author Share Posted September 25, 2017 Sorry, you're right. I put the little bit in a 14 % vinegar and it didn't fizz.

abyssunder Posted September 25, 2017 Share Posted September 25, 2017 Then maybe they are Beekite .

abyssunder Posted September 26, 2017 Share Posted September 26, 2017 Not the same color, I agree, but I'm wondering what might be the origin of the greenish color in the following samples (?): picture from here picture from here Are the green colors produced by organisms using sunlight to produce chlorophyll or it is green rust (green iron sulfide)?

fifbrindacier Posted September 27, 2017 Author Share Posted September 27, 2017 The fossils found on the foreshore in that place have a matrix more greenish than the one on the coast.
