Platycrinites niotensis Diminutive Crawfordsville CrinoidDescription: Well-preserved example of a Camerate crinoid known as Platycrinites niotensis (Family Platycrinitidae). This species of Platycrinites has a less contorted stem than some such as Platycrinites hemisphericus and P. saffordi. The crinoid is very three-dimensional in aspect, with preservation of the fine pinnules quite evident, and much of the stem attached. This is a fine example of the variety of diverse crinoids to be found in the Crawfordsville deposits.
