Raro e bello, naturale - Animale fossilizzato - Ophiuroidea - 16.5 cm - 16 cm
Period: Ordovician
From: Morocco
About 440 million years ago. Brittle stars are similar in appearance to starfish and are echinoderms
Characteristics: The body structure of snake tail is similar to that of starfish, but the body disk is relatively large, with 5 wrists, and there is an obvious junction between the disk and the wrist, while the junction between the wrist and disk of starfish is often not obvious.
Like starfish, although snaketails have been distributed around the world since the Paleozoic Era, fossils are uncommon. This fossil is very special
