erous heavy teeth which form three more or less complete rows on 

 each side. The lateral rows are typically bifid, but the two inner or 

 medial rows are characteristically rosette shaped. They have promi- 

 nent projections from the dorsal and ventral margins of the crowning 

 ring of subteeth, with the rest of the ring notched and subdivided 

 into six to eight additional teeth. The entire tooth looks somewhat 

 like an anemone, or the top of a thistle (fig. 15b).
