Cylindracanthus rectus
A section of rostrum. Note the breaks showing the usual fragments as they are found. This rostrum is unusual because the three segctions were found together. The tiny teeth are clearly shown in this image on the righthand segment.
A unique specimen of a partial head with the sclorotic ossicle in the eye socket. This is the only known skull of this species that I am aware of. Preserved in a calcarious septarian cement stone and is of exceptional quality
