Ancient Species -

Blastoids looked like small shaggy flowers with great numbers of tiny arms extending from the body. In fossils, these tiny arms are rarely visible, leading to blastoids being called "sea buds". The body was almost covered by thick v-shaped plates almost enclosing the area on top of the animal where food, collected by the arms, was taken into the mouth. Their bodies sat on top of jointed stalks which usually broke apart soon after the blastoid died.

Blastoids first developed in the seas of the Ordovician Period (505 to 434 million years ago. Large colonies were abundant from the Silurian to the Carboniferous Period (434 to 285 million years ago).
