- 485 million years old
Crinoids are marine animals that are part of the phylum Echinodermata, which makes them relatives to starfish, sea urchins, and sea cucumbers.
One of our oldest fossils, crinoids have lived in oceans since at least the Ordovician Era (485 million years ago). These fragments were part of their tube-like stem, which served as their water vascular system.
Crinoids were surprisingly resilient. They survived the Permian Period, which ended with the largest mass extinction event in history, and recent fossil discoveries suggest that these flower-like creatures may have even crossed seas by attaching themselves to driftwood.
They flourished to their peak during the Mississippian period, when the shallow, marine environments they preferred were widespread on several continents. They diversified into hundreds of varieties, most famously the sea lily and feather star that still inhabit oceans today.
2–3 crinoid fossils displayed in an acrylic case.
A perfect addition for your fossil collection.

This little box of fossils is really great, the quality of the fossils is very nice, they are small, but they are exquisitely detailed. I purchased the Fossil specimen for two reasons, first I have a BA Major in Geography and have always be fascinated by Paleontology, but most importantly when I'm faced with a particularly difficult day, I can always pick up the small box and look at something from so far back in time (485 Million years) that it really puts things in perspective and makes me realize how so fleeting are lives are and not to sweat the small stuff.
Received a decently sized trio in a clean display. Very pleased.
