Invertebrate Paleontology Devonian Goniatites from Nevada

House University Museum, Oxford With plate 32 Abstract: Several goniatites recently found in the Nevada Limestone and Pilot Shale * Nevada are described. A new species, Erbenoceras erbeni, is erected for specimens from *< Lower Nevada Limestone in the Cortez Mountains and is thought to be of Emsian age. -im higher in the Nevada Limestone in the southern Roberts Mountains, but below the »3-known Siringocephahts-hezting level, occurs Cabrieroceras aff. crispiforme, which would -Tear to indicate a basal Givetian horizon. A poorly preserved lmitoceras is recorded ~tn the Pilot Shale in the Pahranagat Range. All these three genera are recorded from «Tada for the first time. Comments are made on the palaeogeographic significance of the Tjrrence of these distinctively European forms in the western United States. Introduction Through the kindness of Dr. J. G.

Suture with Pointed Flank Lobe and ... -.: Palaeontologia Polonica
210 JERZY DZIK Genus Posttornoceras Wedekind, 1910 Type species: Posttornoceras balvei Wedekind, 1910 from the mid Famennian Platyclymenia annulata Zone of the Rhenisch Slate Mountains. Diagnosis. — Suture with pointed flank lobe and angular or pointed dorsolateral lobe. Remarks. — Becker (1993b) proposed Exotornoceras for the most primitive members of the lineage with a relatively shallow dorsolateral lobe. The difference seems too minor and continuity too apparent to make this taxonomical subdivision practical. Becker (2002) suggested that this lineage was rooted in Gundolficeras, which is supported by the data from the Holy Cross Mountains. The suture of Posttornoceras is similar to that of Sporadoceras, but these end−members of unrelated lin− eages differ rather significantly in the geometry of the septum (Becker 1993b; Korn 1999). In Posttornoceras the parts of the whorl in contact with the preceding whorl are much less extensive, the dorsolateral saddle is much shorter and of a somewhat angular appearance. This is obviously a reflection of the difference in the whorl expansion rate between the tornoceratids and cheiloceratids. Posttornoceras superstes (Wedekind, 1908) (Figs 154A and 159) Type horizon and locality: Early Famennian at Nehden−Schurbusch, Rhenish Slate Mountains (Becker 1993b). Diagnosis. — Suture with pointed tip of the flank lobe and roundedly angulate dorsolateral lobe. Remarks.—Gephyroceras niedzwiedzkii of Dybczyński (1913) from Sieklucki’s brickpit was repre− sented by a specimen (probably lost) significantly larger than those described by Becker (1993b). The differ− ence in proportions of suture seem to result from this ontogenetic difference, that is mostly from increase of the whorl compression with growth. Distribution. — Reworked at Sieklucki’s brickpit in Kielce. -

Paleontological Contributions
THE UNIVERSITY OF KANSAS PALEONTOLOGICAL CONTRIBUTIONS May 15, 1970 Paper 47 SIGNIFICANCE OF SUTURES IN PHYLOGENY OF AMMONOIDEA JURGEN KULLMANN AND JOST WIEDMANN Universinit Tubingen, Germany ABSTRACT Because of their complex structure ammonoid sutures offer best possibilities for the recognition of homologies. Sutures comprise a set of individual elements, which may be changed during the course of ontogeny and phylogeny as a result of heterotopy, hetero- morphy, and heterochrony. By means of a morphogenetic symbol terminology, sutural formulas may be established which show the composition of adult sutures as well as their ontogenetic development. WEDEKIND ' S terminology system is preferred because it is the oldest and morphogenetically the most consequent, whereas RUZHENTSEV ' S system seems to be inadequate because of its usage of different symbols for homologous elements. WEDEKIND ' S system includes only five symbols: E (for external lobe), L (for lateral lobe), I (for internal lobe), A (for adventitious lobe), U (for umbilical lobe). Investigations on ontogenetic development show that all taxonomic groups of the entire superorder Ammonoidea can be compared one with another by means of their sutural development, expressed by their sutural formulas. Most of the higher and many of the lower taxa can be solely characterized and arranged in phylogenetic relationship by use of their sutural formulas. INTRODUCTION Today very few ammonoid workers doubt the (e.g., conch shape, sculpture, growth lines) rep- importance of sutures as indication of ammonoid resent less complicated structures; therefore, phylogeny. The considerable advances in our numerous homeomorphs restrict the usefulness of knowledge of ammonoid evolution during recent these features for phylogenetic investigations. -
