Welcome.
This is an outstandingly detailed Crinoid. It is an almost complete animal. The details are so crisp and delicate it nearly looks like a wet tissue that if touched would easily tear. You do not need to look hard to see the fine filaments (pinnule) extending from the arms. The calyx is in fine clarity and the hexagonal plates which create it are clearly seen. The stem segment is intact along with several others. And there appears to be the faint remnants of a sister flower spread to the left of the main flower.
These crinoids date to the Silurian and Devonian Periods of the Paleozoic Era, 443 Million Years Ago to 358 Million years ago. Crinoids were filter feeders. Anchored to the sea floor, a long stem would extend up to the crown. The pinnule are the very fine filaments that would collect microscopic plankton and other sea life that flowed through them to then be consumed as food.
An acrylic stand is included.
