Superb Brachiocaris Phyllocarid Fossil from Wheeler Shale

It is unusual to have a good positive and negative phyllocarid as one half is usually partially covered by matrix. This specimen is also unusual in having such good contrast. The taxon is also known from the Burgess Shale of British Columbia, while another member of the genus has been found in the Chengjiang Biota. Phyllocarids are one of the lesser known branchiopod crustaceans from the Cambrian where they are among the earliest animals with a hard shell.
