Not collected by me

This specimen was a high-school graduation gift from a good friend of mine. It is my favorite genus of crinoids from the Upper Mississippian, but I have not been able to find one yet. Anartiocrinus has two hypertrophied arms and eight normal-sized arms. The purpose of the two large arms is a bit of a mystery. Some modern crinoids have enlarged arms that they use for crawling on the seafloor, but since Anartiocrinus has a stem, mobility might not be the answer. The big arms taper to a whip-like point, and are usually much longer. In my specimen, the big arms are not complete.

I collected this specimen with my dad when I was 9 years old. It is still one of my favorites, and it's definitely one my most photogenic crinoids.

Note the recumbent arms. This is an adaptation that allowed the crinoid to fold its arms over the cup. It helped with filter feeding. In life, the cup would not be exposed, but because of weathering, the top of the cup is visible on this specimen.
