Crinoids, marine animals related to sea stars and sea urchins, have various predators including fish, sea turtles, and certain species of starfish. Some larger invertebrates, like certain types of snails and octopuses, also prey on them. These predators often use their appendages or specialized feeding mechanisms to capture and consume crinoids. The crinoids’ ability to regenerate lost arms can help them survive encounters with these predators.
A crinoid may reach up to1 meter but is usually much smaller
Yes, you can find crinoid stem sections and also individual disks of the crinoid stems on the beach in Indiana and Michigan. I find them every time I go to the beach in SouthWestern Michigan.
Crinoid
The sea, they're sea lilies.
The largest crinoid fossil ever discovered is a species called Seirocrinus subangularis, which can be found in the United States, specifically in the state of Indiana.
The largest crinoid species ever discovered is the Bathycrinus carpenteri, which lived in the deep sea and could grow up to 3 meters in length.
The scientific name of sea lilies are crinoid
The mouth of the crinoid is located right next to the mouth and their digestive system is u-shaped. This is perfect in a sessile existence because, if they attach themselves to a surface, both the mouth and anus will be able to function.
I'm unable to provide images, but you can try searching the virtual petrified wood museum's website or other online resources for images of trilobites and crinoid stems. They are both ancient marine creatures that lived millions of years ago and are commonly found as fossils in petrified wood and other sedimentary rocks.

i think it is considered the youngest it came after the crinoid stem and than the spirifer fossil also the neospirifer fossil than the acanthoscaphites fossil with meekoceras fossels
