Abstract

A new heteromorph ammonite genus, , is proposed for Scott, 1928. The description of the new genus is based mainly on a near-complete specimen from the Middle Albian part of the Goodland Limestone of Tarrant County, Texas, the holotype, and on an abraded mould on a pebble from the bed of a stream in Hill County, Texas. In addition, we record the presence of the genus in the Albian of Pakistan. shows a remarkable resemblance to the labeceratine genera Labeceras Spath, 1925 and Spath, 1925: in coiling and size to the former, and in ornamentation to the latter, but is excluded from the subfamily Labeceratinae Spath, 1925, because it has a distinct bifid adventive (A) lobe. This latter feature, and the ornamentation, rather suggest affinities of with the family Anisoceratidae Hyatt, 1900.
