Undescribed Crinoid #1

Waldron Shale Formation

Shelby County, IN
Silurian

Here is an exceedingly rare and diminutive crinoid that is undescribed. It is easily overlooked due to its lack of size. This specimen is probably at the maximum spectrum of growth measuring 5/8" long with 1/4" of stem. Even the fine pinnules are fossilized which adds to the aesthetic display of this rare Waldron Shale crinoid.

Here is another diminutive crinoid that, as far as I am able to tell, is undescribed. It is easily overlooked due to its lack of size. This specimen is probably at the maximum spectrum of growth measuring 3/4" long. Even the fine pinnules are fossilized which adds to the aesthetic display of this rare Waldron Shale crinoid.
