1.6" Edrioasteroid (Edriophrus) Fossil - Brechin, Ontario

This is a beautifully preserved, Edrioasteroid (Edriophrus levis) fossil from Brechin, Ontario. It's located on a thick section of limestone. The quarry where these Edrios come from has been closed to collecting for some time.

Edrioasteroids are an extinct class of echinoderms that lived from the Ediacaran until the Permian, about 300 million years ago. The living animal would have resembled a pentamerously symmetrical disc or cushion.
