Shellseeker Posted February 7, 2019 Share Posted February 7, 2019 Recently I purchased France sand dollars from @Coco. See this thread http://www.thefossilforum.com/index.php?/topic/92032-diverse-french-fossils-to-be-sold/ The 5 Parascutella_producta arrived Tuesday safe and sound with well designed packaging. One was a double and Coco added a sixth that she had polished on her club's water based buffing machine. In addition, a bonus of a little sea urchin Arbacina monilis was unexpected. I was greatly pleased for an excellent transaction. Polished Parascutella_producta Arbacina monilis Now I must figure out how to remove the sand-limestone like Coco did. I have a friend who has a vast collection of echinoderms and asked for advice. He uses no mechanical device beyond water and a knife and he has cleaned thousands of fossils, which he shows off at Fossil Club shows. It seems that there is only a light covering of sand_limestone so I will try his method on one of my 5. In Process. I also have a dremel and a compressor-air blaster which I have never used. Maybe I will get to them. My thanks to Coco, for beautiful new additions to my collection. I'll put the one she polished in a riker box and see if I can match the beauty on one of the others.

Tidgy's Dad Posted February 7, 2019 Share Posted February 7, 2019 Nice echinoids. The polished one looks gorgeous. Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
Darktooth Posted February 7, 2019 Share Posted February 7, 2019 I agree with Adam, the polished one looks fantastic. I like Trilo-butts and I cannot lie. Link to comment Share on other sites More sharing options...
Coco Posted February 7, 2019 Share Posted February 7, 2019 Hi, They have been found in a layer of sand, which is exceptional because they are usually crusted and can't be prepared so finely as these. Here the quality is incomparable. I’m glad you like them Shellseeker !

Plantguy Posted February 8, 2019 Share Posted February 8, 2019 Cool additions Jack! Good luck in the prep. The vulcan Rhyncholampus echys I've had moderate success with using just a knife and a brass wire brush to get the worst of the stuff off...some bits however are very stubborn. Wish you had some pieces you could experiment on...looks like too nice of material to goof around with.... Regards, Chris Link to comment Share on other sites More sharing options...
Coco Posted February 8, 2019 Share Posted February 8, 2019 Hi, Little sea urchin from Noyant-la-Plaine is Arbacina monilis.
