  • Halkieria evangelista was originally interpreted as a stem‐group brachiopod. It was later proposed that the brachiopods evolved from a halkieriid ancestor that curved ventrally, lost the foot and radula, developed a lophophore as a new feeding organ, and modified the sclerites to chaetae. Molluscan affinities have been discussed by a number of authors. We have studied some of the original material of Halkieria and found that all the characters that can be observed with certainty are compatible… CONTINUE READING
