Are among the oldest and primitave of ocean invertibrates. To feed they would stretch their arms to catch tiny plankton. Tiny finger like tube feet that line the featherlike arms, flick passing bits of plankton into special food gutters then run along the centre of each arm; microscopic cilia carry the food along the gutter floors to the mouth. The number of arms a Crinoid has varies widely between species: some may have as many as 200 each and up to 14 inches in length. Crinoids are distinguised from other echinoderms by the fact that their mouth is pointed upward, unlike their starfish cousins. There are nearly 550 special of crinoids worldwide.
I found this on a hike at the top of a mountain. It's amazing to find fossils of shells, and other ocean sealife in our mountains. Millions of years ago, the Rocky Mountains were under the sea.

I'm not on my home computer and can't
