Orthoceras moved around with jet propulsion in ancient Ordovician waters. They were avid hunters who could squirt ink, much like their modern day relative the squid, at a predator. Kenric Laiwakete's Horse
with turquoise inlaid eyes hosts an extraordinary orthoceras specimen. One side of this approximate 2 1/4" long, 1/2" wide and 1 1/2" tall pony is inlaid with a turquoise heartline.
