Comments -- First described by Pander, a century ago, these elements are described as coniform, recurved, with a rounded face and single costa, and deep basal cavity, and have been classified in the genus Panderodus, created by Ethington in 1959  The apparatus of this animal contained many similar elements that differed slightly in shape and curvature.
