We wish to acknowledge here the preparation of the specimen by the late Will Downs. Even though this is a small and less than desirably preserved specimen, his preparation was meticulous as always. Reviews by L.L. Jacobs and M.J. Polcyn greatly improved the manuscript. J.C. Cisneros and S. Modesto kindly provided useful literature and discussions on procolophonids. We also thank H.-D. Sues for information regarding unpublished material from Arizona.
