CrinoidsIt always sort of amazes me that these are animals. Crinoids are part of the Echinoderms – the same phylum that includes starfish and sea urchins. They are filter feeders, either attached to the seafloor or sometimes floating through the water column, picking up little bits of plankton and other passing organic matter as food. There are a number of extant species of them, but they were far more abundant in the oceans in the Paleozoic and Mesozoic. Most of the time, they are found as little disks from the columns having broken up, but occasionally they can be preserved in tact if they are buried rapidly after death in areas with little current flow or predation. These articulated crinoids are on display at the Beaty Biodiversity Museum in British Columbia, Canada.  -JBBImage source:https://flic.kr/p/2gUpd81 -- source link
