Coco Posted November 28, 2012 Share Posted November 28, 2012 Post n° 458 : I think I have seen this sea urchin on TFF, and I told that for me it can't be a fossil one, I explained why, for example colours, pores not fill (perform) with sediments etc.... . I think it is a recent specimen with something inside. Post n° 459 : Amphiope bioculata could comes from Maine-et-Moire (mine) or Indre-et-Loire department. They are Miocene.

Coco Thanks Coco Here's a link to an almost identical specimen to mine... light green in color. Except it still has a bit of matrix on it's shell, and from the image of it there doesn't seem to be any sediment in the pores as well. Other specimens of Schizechinus also has the same traits...? http://www.echinologia.com/thumbsirregulierspage26toxopneusiticidaridae/imagepages/image2.htm Link to comment Share on other sites More sharing options...
Coco Posted November 29, 2012 Share Posted November 29, 2012 Hi, I am a member of Echinologia. If you agree, I could put your pic on this forum and ask them their advice.

Coco Posted November 30, 2012 Share Posted November 30, 2012 Hi, Here is a first answer : "Il faut tester la gangue avec du vinaigre: si c'est effervescent, il y a du calcaire, si non, c'est que du platre...". It means : You have to test the matrix with some vinegar. If it is effervescent it is because there is some limestone. If not, it is only some plaster (and thus of the false matrix). I add : take care not to put any vinegar on the sea urchin because that is going to eat it. And rinse with a lot of water after the experience.

Scylla Posted December 4, 2012 Share Posted December 4, 2012 maybe it would be safer to dip a small chip of the matrix in vinegar after removing it from the fossil, it will still answer the question, but you won't have to worry about spillage and washing.
