dani Posted March 17, 2014 Share Posted March 17, 2014 I just joined this forum so first I want to say hello to eveyone! Next, I found this on the Black Sea beach, it probably come out from the sea. Since the shape is not conical I posted two pictures showing both sides. Other informations: it is 4.5 cm high; a small part is measing so I can not say how thick is at the base but at least 1 cm ; Is quite heavy and is easy to break. Thanks!

Auspex Posted March 17, 2014 Share Posted March 17, 2014 In the images, the structure seems bone-like.

Tethys Posted March 21, 2014 Share Posted March 21, 2014 It could be a gypsum, lime mineral concretion. It also resembles a volcano barnacle, but I've never seen a fossil barnacle. Link to comment Share on other sites More sharing options...
Coco Posted March 21, 2014 Share Posted March 21, 2014 Hi, The structure looks like the aragonite or quartz. It isn't "volcano banacle" because this is a "cirripède" (in french). It is shellfish constituted by numerous small plates, while the shown element seems in a single part.

dani Posted April 1, 2014 Author Share Posted April 1, 2014 Hello again and sorry for the delay. To Herb: yes, you can detach with your fingernail small fragments, not extremely easy but you can do it. In fact, when I found this piece I lift it from the sand and instinctively I tried to break it, and it was easy to split it in two fragments. Ofcourse, when I realize it maybe something interesting I was not so happy. I intend to go to the geology museum and ask them for an opinion. I'll be back with their opinion.

cowgirlfossils Posted April 1, 2014 Share Posted April 1, 2014 Seems similar to this? Or I could be totally off.... Link to comment Share on other sites More sharing options...
Herb Posted April 3, 2014 Share Posted April 3, 2014 If you can scratch it with your fingernail it is probably some form of gypsum crystals.

dani Posted May 14, 2014 Author Share Posted May 14, 2014 I have an answer. It is phosphorite. I showed the sample to a paleontologist. For rock identification what book would you recommand (beginner level) ? Daniela Link to comment Share on other sites More sharing options...
