Submitter notes: Here is a very complete example of a Phillocarid mandible or Gastric tooth. These are attributed to the two largest species of Phillocarid, either Dithyrocaris or Herbertocaris. It isn't clear which. This very complete jaw or attachment structure is rarely preserved. The "teeth" are 3.5 cm or 1 inch long
the matrix is 9.5 cm by 6 cm. collected by me on 6/28/14.
