What is it that makes fossilized crinoids so compelling? Is it the artful way these delicate creatures came to rest at the bottom of the sea? Or the amazing transformation from living animal to rock, forever preserved, then heaved and eroded from the depths of time? Or is it the sheer success of this class of echinoderms as a survivor—living, reproducing, and dying over millions and millions of years to this very day in the depths of the oceans?
I discovered the fossilized Uintacrinus socialis, a floating crinoid species whose arms could reach three feet long, at the Smithsonian Museum of Natural History in Washington, DC, and at Yale’s Peabody Museum of Natural History in New Haven, Connecticut. I found the other beautiful specimens (depicted below) at the Beneski Museum at Amherst College in Massachusetts (Platycrinus and Dichocrinus sp.) and the Peabody Museum (Sea Lily).
Tips & Techniques– Studying the anatomy of creatures you’re interested in painting can make a world of difference. Not only will it help you get the drawing right, it will deepen your understanding and appreciation for the nature of the world. Drawing the anatomy of a crinoid helped me figure out what features to look for in the fossil specimens and to see the similarities between crinoids and their echinoderm relatives– sea stars and urchins.
