Abstract

Trachyscaphites pulcherrimus, described originally by Ferdinand Roemer in 1841 from fragments of nodose ammonites from Germany, is characterized by having five rows of tubercles on each flank of the phragmocone and three to five rows on each side of the body chamber. Weak midventral tubercles are present on some specimens. Ribbing is dense and usually irregular. The species has been recorded from upper Campanian rocks in Germany, Austria, France, Poland, and Russia. Recently a few specimens have been found at the top of the Wenonah Formation of New Jersey and in the Taylor Marl of Texas.
