Echinoderm? Part of brittle star or crinoid?


Re-Elu

Recommended Posts

Found this on a Dutch beach (Zandmotor) 6 months ago. Max. diameter appr. 14 mm.

Shape looks somewhat like a pentagon. Two sides have openings in them (marked a and b in pictures), within each opening there there seems to be a bit dividing both openings in two halves.

Ar least one of the corners of the pentagon seems to have had a protrusion (stalk, arm?) that has broken off. Encircled in the pictures.

Due to the shape, the openings, and the broken off bit this looks like like some echinoderm fossil to me. But which one? Any ideas?

Sorry, but I am not seeing anything fossil related here.

It looks more like quartz based rock.
