[Note Guidelines] Photographer's Note
CRINOID (Echinoderms)
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.

Les oiseaux me fascinent, me passsionnent. Mais, j'ai toujours été impressionné lorsque je découvrais et examinais des fossiles en Gaspésie. La raison: leur âge.
Cette photo, tout comme la note, est très intéressante par la variété de fossiles. excellente lumière, couleurs naturelles. Merci.

(Je souhaite bonne chance à vos Oilers. Ils le méritent)

Hi Janice,
here you have captured something that brings back good memories for me.I as a boy loved to collect fossils as they provided an almost endless fascination to me.I had trilobites and shells and corals of many different types,I never did find me a dinosaur though.I find no fault in this photo's presentation or it's colour,good capture.One more thing Alberta's gemstone is the most iridescence of all things that is a fossil,the Ammonite.
