Despite that there are about 600 Crinoid species, they’ve mostly gone extinct. Being a marine animal, their fossils are mostly found in thick limestone beds dating to the mid-to-late-Paleozoic. [http://bit.ly/2j9r9ml]
fms.fossils This is a small crinoid fossil of the species Pentacrinites fossilis I found at Charmouth a few months ago. It was just a small single piece that was incredibly thin and delicate sticking out of the mud. When I cleaned it up at home I was pleasantly surprised by the detail! It shows a complete head that has been preserved with all of the arms and pinnules flowing over to the right hand side. This shows how water currents, or the movement of the crinoid through the water affected the positing of the animal as it came to rest on the seafloor. A nice little snapshot of history 196 million years old.
It’s time for #TrilobiteTuesday! Every trilobite fossil tells a unique and often compelling tale. Whether it’s a 500 million-year-old Hemirhodon amplipyge bearing a potentially fatal bite mark like the one pictured here, or a 450 million-year-old Primaspis crosotus appearing forever frozen amid a fossilized field of crinoid stems, each example of these primeval life forms possesses the capacity to provide a captured-in-time glimpse of a long-gone undersea kingdom. With a trilobite in hand and a healthy imagination at play, each of us can partake in a private sojourn back to a time when trilobites first filled the planet’s oceans.
I want to make a series of images of prehistoric oceanscapes called Lost Oceans. This is the early Cambrian feat. Anomalocaris, which you may know as the inspiration for the pokemon Anorith. Other friends include various trilobites, Opabinia, Marella, Pikaia, Hallucigenia, crinoids (sea lillies), Kimberella, Wiwaxia, arcaeocyathid sponges, stromatolites, brachiopods, other invertebrates, and red algae.

kiwigreg71 250 million year old crinoid #fossil on perfect display in a museum. Basically they are a marine plants with stems like a life-saver candy. Go to the rim of the #grandcanyon and you’ll be standing on thousands of these.
