Rarely-seen Burgess Shale Waptia

Description: Waptia fieldensis is an unusual bivalved arthropod that comprises some 2.5% of the Burgess Shale specimens collected. While it is most assuredly an arthropod, it is as yet unclear as to its affinities. This specimen is primarily the jointed abdomen. For more complete examples of the slightly older Chengjiang Biota, see my offerings from that locality. Coming from the famous Burgess Shale Fauna, this is a highly-desirable member which will make a fine addition to any collection of Cambrian Explosion fossils.
