CONODONTS OF THE MOJCZA LIMESTONE JERZY DZIK Dzik, J. 1994. Conodonts of the M6jcza Limestone. -In: J. Dzik, E. Olemp ska, and A. Pisera 1994. Ordovician carbonate platform ecosystem of the Holy Cross Moun tains. Palaeontologia Polonica 53, 43-128. The Ordovician organodetrital limestones and marls studied in outcrops at M6jcza and Miedzygorz, Holy Cross Mts, Poland, contains a record of the evolution of local conodont faunas from the latest Arenig (Early Kundan, Lenodus variabilis Zone) to the Ashgill (Amorphognathus ordovicicus Zone), with a single larger hiatus corre sponding to the subzones from Eop/acognathus pseudop/anu s to E. reclinatu s. The conodont fauna is Baltic in general appearance but cold water genera , like Sagitto dontina, Scabbardella, and Hamarodus, as well as those of Welsh or Chinese af finities, like Comp/exodus, Phragmodus, and Rhodesognathu s are dominant in par ticular parts of the section while others common in the Baltic region, like Periodon , Eop/acognathus, and Sca/pellodus are extremely rare. Most of the lineages continue to occur throughout most of the section enabling quantitative studies on their phyletic evolut ion. Apparatuses of sixty seven species of thirty six genera are described and illustrated. Phyletic evolution of Ba/toniodus, Amorphognathu s, Comp/exodus, and Pygodus is biometrically documented. Element s of apparatu ses are homolog ized and the standard notation system is applied to all of them. Acodontidae fam. n., Drepa nodus kie/censis sp. n., and D. santacrucensis sp. n. are proposed .

Misikella Ultima Kozur & Mock, 1991: First Evidence of Late Rhaetian
Bollettino della Società Paleontologica Italiana Modena, Novembre 1999 Misikella ultima Kozur & Mock, 1991: first evidence of Late Rhaetian conodonts in Calabria (Southern Italy) Adelaide MASTANDREA Claudio NERI Fabio lETTO Franco Russo Di p. di Scienze della Terra Di p. di Se. Geo!. e Paleomol. Dip. di Scienze della Terra Dip. di Scienze della Terra Univ. di Modena e Reggio Emilia Università di Ferrara Università di Napoli Federico II Università della Calabria KEY- WORDS- Conodonts, Clusters, Biostratigraphy, Basin deposits, Catena Costiera, Calabria, Rhaetian. ABSTRACT- The succession cropping out in the Fosso Pantanelle area (Mt. S. Giovanni, Calabrian "Catena Costiera'; Upper Trias) provided a rich and well preserved conodont fauna. The basin stratigraphic succession is characterized by cherty lime mudstone with minor fine- grained calciturbidites and suspected tujìtes. Conodont founa is dominated by M. hernsteini and M. posthernsteini in the lower and middle part of the section, and by M. uftima in the uppermost part. Every species is represented by a great number of specimens. On the basis of the chronostratigraphic classification ofKozur & Mock (1991), the whole section may be referred to Rhaetian. Due to the good preservation and the great abundance of conodonts (some occurring in clusters), the calabrian Catena Costiera succession may represent a reference succession for the study ofthe latest Triassic conodont founas and chronostratigraphy.

Geology and Impact Features of Vargeo Dome, Southern Brazil

E-mail: [email protected] (Received 14 December 2010; revision accepted 2 November 2011) Abstract–Vargea˜o Dome (southern Brazil) is a circular feature formed in lava flows of the Lower Cretaceous Serra Geral Formation and in sandstones of the Parana´Basin. Even though its impact origin was already proposed in the 1980s, little information about its geological and impact features is available in the literature. The structure has a rim-rim diameter of approximately 12 km and comprises several ring-like concentric features with multiple concentric lineaments. The presence of a central uplift is suggested by the occurrence of deformed sandstone strata of the Botucatu and Pirambo´ia formations. We present the morphological ⁄ structural characteristics of Vargea˜o Dome, characterize the different rock types that occur in its interior, mainly brecciated volcanic rocks (BVR) of the Serra Geral Formation, and discuss the deformation and shock features in the volcanic rocks and in sandstones. These features comprise shatter cones in sandstone and basalt, as well as planar microstructures in quartz. -
The Tennessee Meteorite Impact Sites and Changing Perspectives on Impact Cratering
UNIVERSITY OF SOUTHERN QUEENSLAND THE TENNESSEE METEORITE IMPACT SITES AND CHANGING PERSPECTIVES ON IMPACT CRATERING A dissertation submitted by Janaruth Harling Ford B.A. Cum Laude (Vanderbilt University), M. Astron. (University of Western Sydney) For the award of Doctor of Philosophy 2015 ABSTRACT Terrestrial impact structures offer astronomers and geologists opportunities to study the impact cratering process. Tennessee has four structures of interest. Information gained over the last century and a half concerning these sites is scattered throughout astronomical, geological and other specialized scientific journals, books, and literature, some of which are elusive. Gathering and compiling this widely- spread information into one historical document benefits the scientific community in general. The Wells Creek Structure is a proven impact site, and has been referred to as the ‘syntype’ cryptoexplosion structure for the United State. It was the first impact structure in the United States in which shatter cones were identified and was probably the subject of the first detailed geological report on a cryptoexplosive structure in the United States. The Wells Creek Structure displays bilateral symmetry, and three smaller ‘craters’ lie to the north of the main Wells Creek structure along its axis of symmetry. The question remains as to whether or not these structures have a common origin with the Wells Creek structure. The Flynn Creek Structure, another proven impact site, was first mentioned as a site of disturbance in Safford’s 1869 report on the geology of Tennessee. It has been noted as the terrestrial feature that bears the closest resemblance to a typical lunar crater, even though it is the probable result of a shallow marine impact. -
