These two images are what I think are Callianopsis clallamensis shrimp fossil claws. They might also be referred to as ghost or mud shrimp. Fossils are from the Washington state area and could be from either the Lincoln Creek or Pysht formations. The date of the fossils is to the Oligocene epoch of the Paleogene Period. The fossils were acquired by my cousin in a trade of fossils from the Louisville Kentucky area on a recent visit to the area.
