Invertebrate Paleontology Devonian Goniatites from Nevada
N. Jb. Geol. Palaont. Abh. 122 3 337—342 Stuttgart. Juni 1965 Invertebrate Paleontology Earth Sciences Division Natural History Museum Devonian goniatites from Nevada By M. R. 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. JOHNSON of the University of Cali- nia at Los Angeles, several Devonian goniatite faunas have been sub- *rted for study and are reported on here. They include the first Middle Vvonian goniatites known from the western United States, and these serve * give a tentative placing of the Eifelian/Givetian boundary in the Nevada -nestone. Also there are two particularly interesting Lower Devonian rcimens which must be from near the level which has yielded the holotype ' Agoniatites nevadensis MILLER, which has recently been considered to be a '-cherticeras (HOUSE 1962, p. 262) and that which yielded Goniatites desidera- * WALCOTT which Dr. -

Message from the New Chairman
Subcommission on Devonian Stratigraphy Newsletter No. 21 April, 2005 MESSAGE FROM THE NEW CHAIRMAN Dear SDS Members: This new Newsletter gives me the pleasant opportunity to thank you for your confidence which should allow me to lead our Devonian Subcommission successfully through the next four years until the next International Geological Congress in Norway. Ahmed El Hassani, as Vice-Chairman, and John Marshall, as our new Secretary, will assist and help me. As it has been our habit in the past, our outgoing chairman, Pierre Bultynck, has continued his duties until the end of the calendar year, and in the name of all the Subcommission, I like to express our warmest thanks to him for all his efforts, his enthusi- asm for our tasks, his patience with the often too slow progress of research, and for the humorous, well organized and skil- ful handling of our affairs, including our annual meetings. At the same time I like to thank all our outgoing Titular Members for their partly long-time service and I express my hope that they will continue their SDS work with the same interest and energy as Corresponding Members. The new ICS rules require a rather constant change of voting members and the change from TM to CM status should not necessarily be taken as an excuse to adopt the lifestyle of a “Devonian pensioner”. I see no reason why constantly active SDS members shouldn´t become TM again, at a later stage. On the other side, the rather strong exchange of voting members should bring in some fresh ideas and some shift towards modern stratigraphical tech- niques. -

This is one of many related papers that were included in the 2009 NMGS Fall Field Conference Guidebook. Annual NMGS Fall Field Conference Guidebooks Every fall since 1950, the New Mexico Geological Society (NMGS) has held an annual Fall Field Conference that explores some region of New Mexico (or surrounding states). Always well attended, these conferences provide a guidebook to participants. Besides detailed road logs, the guidebooks contain many well written, edited, and peer-reviewed geoscience papers. These books have set the national standard for geologic guidebooks and are an essential geologic reference for anyone working in or around New Mexico. Free Downloads NMGS has decided to make peer-reviewed papers from our Fall Field Conference guidebooks available for free download. Non-members will have access to guidebook papers two years after publication. Members have access to all papers. This is in keeping with our mission of promoting interest, research, and cooperation regarding geology in New Mexico. However, guidebook sales represent a significant proportion of our operating budget. Therefore, only research papers are available for download. Road logs, mini-papers, maps, stratigraphic charts, and other selected content are available only in the printed guidebooks.

Geoloaic District. Subsequent Stratigraphic Studies in This Area
DEVONIAN STRATA AND PALEOENVIRONMENTS: CHAUTAUQUA COUNTY REGION: NEW YORK STATE GORDON C. BAIRD and GARY G. LASH Department of Geosciences State University of New York College at Fredonia Fredonia, New York 14063 INTRODUCTION The history of the study of the Paleozoic stratigraphic divisions in New York State spans, at least, two centuries, and it records the early development of important concepts centrally germane to the study of sedimentary basins worldwide (see Tesmer, 1989). The works of James Hall, John Clarke, HenryS. Williams, Joseph Barrell, and George Chadwick are well known to most sedimentary workers, as are those of numerous subsequent workers. In particular, the sedimentary sequences of the Allegheny Plateau Region (••southern Tier" region) served as important sources of information for refinement of the fac ies concept ar.d for the widespread recognition of the westwardly prograding Catskill Delta Complex which is the primary Paleozoic story recorded in Southern Tier bedrock deposits (see Chadwick, 1924, 1933; Cooper, et al., 1942; Caster, 1934; Woodrow, 1985). ---- The first significant geologic work relating to the Chautauqua County region was presented in James Hall's (1843) Survey of the Fourth Geoloaic District. Subsequent stratigraphic studies in this area inclu e Clarke (1903), Chadwick (1923, 1924), Caster (1934), Pepper and de Witt (1950, 1951) and de Witt and Colton (1953). In northwest Pennsylvania, significant synthetic contributions include I.C. White (1881), Butts (1906-1908), Chadwick (1925), Caster ·(1934), Pepper et al. (1954). In Ohio, deposits equivalent to parts of the New York and - Pennsylvania Upper Devonian section (Chagrin Shale) have been the subject of recent paleoenvironmental studies (see Weidner and Feldmann, 1983; Schwimmer and Feldmann, 1990). -

Tentaculites of the Upper Silurian and Lower Devonian of Poland
ACT A PAL A EON T 0 LOG ICA POLONICA Vol. XIX 1974 No. 4 BARBARA HAJI..ASZ TENTACULITES OF THE UPPER SILURIAN AND LOWER DEVONIAN OF POLAND Abstract. - The tentaculites, described in the present paper, come from the Upper Silurian deposits of the Baltic coastal region and the Lower Devonian deposits of the Radom-Lublin region. The Upper Silurian assemblage of tentaculites allows one to compare and correlate the Upper Silurian deposits of Northern Europe. The Lower Devonian tentaculites are' indicative of the Gedinnian and Siegenian age of the deposits under study and of their close correlations primarily with Podolia. PART I INTRODUCTION In Poland, the tentaculites have not so far been described in detail. Giirich (1895) was the first to take an interest in the tentaculites occurring in this country. He described the following species from the Holy Cross Mountains: Tentaculites sp. d. intermedium Barr., T. multiformis Sandb., T.ornatus? Sow., T. schlotheimi Koken., T. polonicus Gurich., T. sand bergeri Gurich, T. tenuicinctus Sandb., Styliolites sp. From the same region, the following species were identified by Paj chlowa (1957): Tentaculites schlotheimi Koken., Tentaculites sp., Styliolina laevis Richter and Styliolina sp. The tentaculites of the species Homoc tenus tenuicinctus (Roem.), Homoctenus sp., Styliolina laevis Richter and Styliolina sp. were distinguished by Koscielniakowska (1962-1967) in the Frasnian deposits of these region. The present writer described the following Eifelian tentaculites from the Holy Cross Mts and the Cracow-Cz~stochowaUpland (Hajlasz, 1967): Tentaculites schlotheimi Koken., T. subconicus Geinitz, T.sp., and Dicri coconus mosolovicus (Ljasch.). Next, a list of species from Lower Devonian of the Lublin area was published (Hajlasz, 1968).
