Platycrinites saffordiDescription: Good example of a Camerate crinoid Platycrinites saffordi (Family Platycrinitidae). This species of Platycrinites has a contorted stem like Platycrinites hemisphericus. The crinoid is very three-dimensional in aspect, with preservation of the fine pinnules quite evident. This is a fine example of the variety of diverse crinoids to be found in the Crawfordsville deposits. Often crinoids are found disarticulated with the crowns detached from the stem, so this one is quite desirable.
