Hello dear forumers!
Yesterday i found something interesting. I think that it is a starfish fragments. It is realy rare for my region. For a years of our hobby we found about 10 pieces at all. Yesterday found about 50 fragments which lay under ground at square about 15x15x10 cm . Some of them layed one after another, but most of it chaotic. At picture 3 and 4 its my vision of how pieces are located one according another.
Is it starfish or ordinary crinoid?
