  • Constraints on the Timescale of Animal Evolutionary History
    Palaeontologia Electronica palaeo-electronica.org Constraints on the timescale of animal evolutionary history Michael J. Benton, Philip C.J. Donoghue, Robert J. Asher, Matt Friedman, Thomas J. Near, and Jakob Vinther ABSTRACT Dating the tree of life is a core endeavor in evolutionary biology. Rates of evolution are fundamental to nearly every evolutionary model and process. Rates need dates. There is much debate on the most appropriate and reasonable ways in which to date the tree of life, and recent work has highlighted some confusions and complexities that can be avoided. Whether phylogenetic trees are dated after they have been estab- lished, or as part of the process of tree finding, practitioners need to know which cali- brations to use. We emphasize the importance of identifying crown (not stem) fossils, levels of confidence in their attribution to the crown, current chronostratigraphic preci- sion, the primacy of the host geological formation and asymmetric confidence intervals. Here we present calibrations for 88 key nodes across the phylogeny of animals, rang- ing from the root of Metazoa to the last common ancestor of Homo sapiens. Close attention to detail is constantly required: for example, the classic bird-mammal date (base of crown Amniota) has often been given as 310-315 Ma; the 2014 international time scale indicates a minimum age of 318 Ma.

Originally described on the basis of a single specimen including a remarkably complete and well-preserved skull and lower jaw, S. clarki is now known from five additional specimens that preserve portions of the craniofacial skeleton. Collectively, these six specimens represent all elements of the head skeleton except the stapedes, thus making the craniofacial skeleton of S. clarki one of the best and most completely preserved among all known basal mesoeucrocodylians. In this report, we provide a detailed description of the entire head skeleton of S. clarki, including a portion of the hyobranchial apparatus. The two most complete and well-preserved specimens differ substantially in several size and shape variables (e.g., projections, angulations, and areas of ornamentation), suggestive of sexual dimorphism.

  • Chris Van Heerden Scores Big Hollywood Victory!!
    CHRIS VAN HEERDEN SCORES BIG HOLLYWOOD VICTORY!! Los Angeles, CA (May 14, 2015) On Wednesday night in Hollywood, California, world ranked welterweight CHRIS “The Heat” VAN HEERDEN improved to 23-1-1 (12KO’s) with a fourth round stoppage over battle tested veteran RAMON AYALA, 23-4-1 (11KO’s) in front of a huge crowd at the Dolby Theater in the main event of the annual Sugar Ray Leonard Foundation card. “I’m very happy with my performance, Ayala was a tough, durable fighter but I’m glad to get back in the ring and look forward to my next opportunity”, said the 27-year-old Van Heerden, a native of South Africa, now residing in Southern California. “This is what would have happened to Frankie Gavin,” continued Van Heerden. “I hope Eddie Hearn gives me a chance against Kell Brook.” “Chris showed that even with the Frankie Gavin fight falling out he stayed focused in his training and was 100% prepared for victory” said MICHAEL KING of KING PROMOTIONS. “We’d like to thank Sugar Ray Leonard and his team and look forward to announcing Chris’ next fight in the near future. Van Heerden entered the fight ranked #13 by the International Boxing Federation. ABOUT KING SPORTS King Sports is a company started by entertainment entrepreneur Michael King.

  • The Stratigraphy and Structure of the Kommadagga Subgroup and Contiguous Rocks
    THE STRATIGRAPHY AND STRUCTURE OF THE KOMMADAGGA SUBGROUP AND CONTIGUOUS ROCKS by ROGER SWART B.Sc . (Hons) Thesis presented in fulfilment of the requirements for the degree of Master of Science in the Department of Geology, Rhodes University ,Grahamstown. January 1982 ABSTRACT The Lake Mentz and Kommadagga Subgroups were deposited i n a marine environment and are characterised by a heterogeneous sequence of sediments, which range in grain size from clays to grits . During the first phase of deposition the Kwee~ vlei Shale and Floriskraal Formations were deposited in a prograding shoreline environment, whereas the succeeding Waaipoort Shale Formation is interpreted as represnting a reworked shoreline. The final phase of deposition of the Cape Supergroup was a regressive one in which the Kommadagga Subgroup wa s fo rmed. The coa rs eni ng upward cycle of thi s subgroup represents a deltaic deposit. A significant time gap appears to exist before the deposition of the glacial-marine Dwyka Tillite Formation. Structurally, the area was subjected to deformation by buckle folding at about 250 Ma into a series of folds with southward dipping axial planes. Only one phase of deformation is recognised in the study area . A decrease in pore space, mineral overgrowths,formation of silica and calcite cements and development of aut~igenic minerals such as opal, stilpnomelane; analcite, prehnite, muscovite and various clay minerals are the characteristic diagenetic features of the sediments.The mineralogical evidence suggests that the maximum temperature

  • South African Research on Volcanic and Related Rocks and Mantle-Derived Materials: 2003-2006
    South African Research on volcanic and related rocks and mantle-derived materials: 2003-2006 J.S. Marsh South African National Correspondent, IAVCEI Department of Geology Rhodes University Grahamstown 6140 South Africa South Africa has no formal organizational or research structures dedicated to the principle aims of International Association of Volcanology and Chemistry of Earth’s Interior (IAVCEI) and over the period of the review there were no national research programmes which advance the main thrusts of IAVCEI. The association has a system of personal membership and the number of IAVCEI members in South Africa has not generally exceeded half a dozen over the period under review, although the potential membership is much greater as there are many scientists carrying out research on volcanic and intrusive rocks as well as mantle materials. These researchers are largely based at universities, the Council for Geoscience, as well as some mining and exploration companies, particularly those with interests in mineralization associated with the Bushveld Complex as well as diamondiferous kimberlite. Over the period of review the research of small informal groups and individuals has produced a substantial number of papers in igneous rocks and mantle materials. These outputs can be conveniently grouped as follows. Archaean Greenstones and Granitoids and Proterozoic Igneous suites. There is a steady output of research in these areas particularly in Archaean suites with interest in both the ultramafic-mafic komatiitic rocks as well as granitoids. Of note is the description of a new class of komatiite characterized by high silica and ultra depletion in incompatible elements. Bushveld Complex The Bushveld Complex one of the world’s largest layered igneous complexes is host to giant ore deposits of Cr, PGE, and V.

    The osteology and phylogenetic position of the loricatan (Archosauria: Pseudosuchia) Heptasuchus clarki, from the ?Mid-Upper Triassic, southeastern Big Horn Mountains, Central Wyoming (USA) † Sterling J. Nesbitt1, John M. Zawiskie2,3, Robert M. Dawley4 1 Department of Geosciences, Virginia Tech, Blacksburg, VA, USA 2 Cranbrook Institute of Science, Bloomfield Hills, MI, USA 3 Department of Geology, Wayne State University, Detroit, MI, USA 4 Department of Biology, Ursinus College, Collegeville, PA, USA † Deceased author. ABSTRACT Loricatan pseudosuchians (known as “rauisuchians”) typically consist of poorly understood fragmentary remains known worldwide from the Middle Triassic to the end of the Triassic Period. Renewed interest and the discovery of more complete specimens recently revolutionized our understanding of the relationships of archosaurs, the origin of Crocodylomorpha, and the paleobiology of these animals. However, there are still few loricatans known from the Middle to early portion of the Late Triassic and the forms that occur during this time are largely known from southern Pangea or Europe. Heptasuchus clarki was the first formally recognized North American “rauisuchian” and was collected from a poorly sampled and disparately fossiliferous sequence of Triassic strata in North America. Exposed along the trend of the Casper Arch flanking the southeastern Big Horn Mountains, the type locality of Heptasuchus clarki occurs within a sequence of red beds above the Alcova Limestone and Crow Mountain formations within the Chugwater Group. The age of the type locality is poorly constrained to the Middle—early Late Triassic and is Submitted 17 June 2020 Accepted 14 September 2020 likely similar to or just older than that of the Popo Agie Formation assemblage from Published 27 October 2020 the western portion of Wyoming.

    Palaeontological Heritage Assessment for Windfarm at Waainek, Grahamstown Compiled for: Gavin Anderson UMLANDO:Archaeological Tourism & Resource Management PO Box 102532, Meerensee, KwaZulu-Natal 3901 Date: February 2011 Compiled by: Robert Gess Bernard Price Institute for Palaeontological Research University of the Witwatersrand c/o P.O Box 40 Bathurst 6166 [email protected] Contents: page 1: Title page 2: Contents page 3: Geology page 4: Palaeontology page 6: Site visit page 6: Conclusions and Recommendations Geology The stratigraphy of the area comprises the upper portion of the Cape Supergroup. The Cape Supergroup is comprised of sediments deposited along the northern edge of the semi-enclosed Agulhas Sea, which opened in response to early rifting between South America, Africa and Antarctia. It is subdivided, from bottom to top, into the Table Mountain Group, the Bokkeveld Group and the Witteberg Group. Of these only the Witteberg Group outcrops in the study area The Witteberg Group is divided into the (lower) Weltevrede Subgroup and the (upper) Lake Menz Subgroup. Weltevrede Subgroup strata are exposed below the development area alongside the N2 and in the bottom of valleys dividing the ridges. The Lake Menz Subgroup consists of four subunits (the Witpoort, Kweekvlei, Floriskraal and Waaipoot formations. The ridge tops within the study area represent, by and large, the more resilient quartzitic strata of the Witpoort Formation. These strata are deeply folded in the area, and quartzitic layers of the overlying Floriskraal Formation may also be represented. Witpoort Formation quartzites are characteristically a clean whitish colour and are latest Devonian, Famennian (approximately 360 million years old).
