1.5" 3D Crinoid (Eucalyptocrinus) Fossil - Middleport, New York
This is a very 3D, Silurian aged crinoid (Eucalyptocrinus) from the Rochester Shale in Middleport, New York. Including the stem section it is 1.5" long and nicely centered on a 4.4 x 4.1" piece of shale. Comes with an acrylic display stand.
Crinoids, sometimes commonly referred to as sea lilies, are animals, not plants. They are echinoderms related to starfish, sea urchins, and brittle stars. Many crinoid traits are like other members of their phylum; such traits include tube feet, radial symmetry, a water vascular system, and appendages in multiples of five (pentameral). They first appeared in the Ordovician (488 million years ago) and some species are still alive today.
