Forbesiocrinus multibrachiatus

Family Synerocrinidae

Size: 30 mm

This is the Flexible crinoid Forbesiocrinus multibranchiatus (Family Synerocrinidae). The Subclass Flexibilia gets its name from the general flexible appearance of the crown (this one looks somewhat like a clenched fist). This is a larger than average example of this type of crinoid. This one very three-dimensional in aspect, a fine example of the variety of diverse crinoids to be found in the Crawfordsville deposits.
