The Carboniferous Evolution of Nova Scotia
Downloaded from http://sp.lyellcollection.org/ by guest on September 27, 2021 The Carboniferous evolution of Nova Scotia J. H. CALDER Nova Scotia Department of Natural Resources, PO Box 698, Halifax, Nova Scotia, Canada B3J 2T9 Abstract: Nova Scotia during the Carboniferous lay at the heart of palaeoequatorial Euramerica in a broadly intermontane palaeoequatorial setting, the Maritimes-West-European province; to the west rose the orographic barrier imposed by the Appalachian Mountains, and to the south and east the Mauritanide-Hercynide belt. The geological affinity of Nova Scotia to Europe, reflected in elements of the Carboniferous flora and fauna, was mirrored in the evolution of geological thought even before the epochal visits of Sir Charles Lyell. The Maritimes Basin of eastern Canada, born of the Acadian-Caledonian orogeny that witnessed the suture of Iapetus in the Devonian, and shaped thereafter by the inexorable closing of Gondwana and Laurasia, comprises a near complete stratal sequence as great as 12 km thick which spans the Middle Devonian to the Lower Permian. Across the southern Maritimes Basin, in northern Nova Scotia, deep depocentres developed en echelon adjacent to a transform platelet boundary between terranes of Avalon and Gondwanan affinity. The subsequent history of the basins can be summarized as distension and rifting attended by bimodal volcanism waning through the Dinantian, with marked transpression in the Namurian and subsequent persistence of transcurrent movement linking Variscan deformation with Mauritainide-Appalachian convergence and Alleghenian thrusting. This Mid- Carboniferous event is pivotal in the Carboniferous evolution of Nova Scotia. Rapid subsidence adjacent to transcurrent faults in the early Westphalian was succeeded by thermal sag in the later Westphalian and ultimately by basin inversion and unroofing after the early Permian as equatorial Pangaea finally assembled and subsequently rifted again in the Triassic. -
Chapter 5. Paleozoic Invertebrate Paleontology of Grand Canyon National Park
Chapter 5. Paleozoic Invertebrate Paleontology of Grand Canyon National Park By Linda Sue Lassiter1, Justin S. Tweet2, Frederick A. Sundberg3, John R. Foster4, and P. J. Bergman5 1Northern Arizona University Department of Biological Sciences Flagstaff, Arizona 2National Park Service 9149 79th Street S. Cottage Grove, Minnesota 55016 3Museum of Northern Arizona Research Associate Flagstaff, Arizona 4Utah Field House of Natural History State Park Museum Vernal, Utah 5Northern Arizona University Flagstaff, Arizona Introduction As impressive as the Grand Canyon is to any observer from the rim, the river, or even from space, these cliffs and slopes are much more than an array of colors above the serpentine majesty of the Colorado River. The erosive forces of the Colorado River and feeder streams took millions of years to carve more than 290 million years of Paleozoic Era rocks. These exposures of Paleozoic Era sediments constitute 85% of the almost 5,000 km2 (1,903 mi2) of the Grand Canyon National Park (GRCA) and reveal important chronologic information on marine paleoecologies of the past. This expanse of both spatial and temporal coverage is unrivaled anywhere else on our planet. While many visitors stand on the rim and peer down into the abyss of the carved canyon depths, few realize that they are also staring at the history of life from almost 520 million years ago (Ma) where the Paleozoic rocks cover the great unconformity (Karlstrom et al. 2018) to 270 Ma at the top (Sorauf and Billingsley 1991). The Paleozoic rocks visible from the South Rim Visitors Center, are mostly from marine and some fluvial sediment deposits (Figure 5-1). -

However, analysis of how this diversity arose has from the fossil record suggests that many clades reach maximal either been based on taxonomic counts (e.g., ref. 23) or has diversity early in their evolutionary history, followed by a decline adopted a morphometric approach where the requirement of a in evolutionary rates as ecological space fills or due to internal homologous set of landmarks limits taxonomic, temporal, and constraints. Here, we apply recently developed methods for esti- geographic scope (e.g., ref. 24). We use a discrete-character- mating rates of morphological evolution during the post-Paleozoic based approach and a recent taxonomically comprehensive history of a major invertebrate clade, the Echinoidea. Contrary to analysis of post-Paleozoic echinoids as our phylogenetic frame- expectation, rates of evolution were lowest during the initial phase work (25). This tree is almost entirely resolved (SI Appendix, Fig. of diversification following the Permo-Triassic mass extinction and S1) and branches may be scaled using the first appearance of increased over time. -
Epizoic Bryozoans on Cephalopods Through the Phanerozoic: a Review

KEY, Jr. 2 1 Department of Geology, Trinity College, Dublin 2, Ireland 2 Department of Earth Sciences, Dickinson College, Carlisle, PA 17013, USA * Corresponding author e-mail: [email protected] SUMMARY - Epizoic bryozoans on cephalopods through the Phanerozoic: a review - Cephalopods have a long geological record and have been utilised by many encrusting organisms as suitable substrates on which to settle and grow. Living cephalopods, dead floating shells, and those lying on the seabed have been encrusted by bryozoans since the Ordovician; these records are reviewed here. Encrusta- tion by bryozoans declined through the Palaeozoic and into the Mesozoic, and few examples of encrustation of modern nautiloids and coleoids have been reported. The patterns of encrustation provides valuable information, firstly, on the palaeobiology of the hosts and the epizoan: some are obligate, but many appear accidental, and secondly, on the sedimentological conditions at the time of fouling of dead shells. Bryozoan-cephalopod interactions may additionally provide valuable data on present and past drifting patterns of shells, and on the palaeo- and biogeographic influences on bryozoan settlement on cephalopods. RIASSUNTO - Briozoi epizoici su cefalopodi attraverso il Fanerozoico: una rassegna - I cefalopodi hanno una lunga documentazione geologica e sono stati utilizzati da molti organimi incrostanti come substrati disponibili su cui impiantarsi e crescere. I cefalopodi viventi, le conchiglie flottanti degli esemplari morti e quelle giacenti sui fondali marini sono state incrostate da briozoi fin dall’Ordoviciano; tutta questa documentazione è qui sintetizzata. -

The First Pennsylvanian Batocrinid and Other New Echinoderms from the Minturn Formation of Central Colorado
The First Pennsylvanian Batocrinid and Other New Echinoderms from the Minturn Formation of Central Colorado WAYNE M. ITANO1 GARY D. WEBSTER2 KAREN J. HOUCK3 WILLIAM D.

Department of Earth Sciences, Denver Museum of Nature and Science, Denver, Colorado 80205 ABSTRACT Middle Pennsylvanian (latest Atokan) strata in the Minturn Formation of north-central Colorado have yielded new specimens of echinoderms, which have not been previously described from the area. Eretmocrinus sawdoi, new species, is the first batocrinid known from the Pennsylvanian. The Batocrinidae (a family of camerate crinoids) were previously thought to have become extinct during the Mississippian. A probable codiacrinid and an unidentified, upflared, infrabasal circlet are additions to the Minturn crinoid fauna. These specimens show that the crinoid fauna is more diverse than previously thought. New speci- mens of Ulocrinus rockymontanus Strimple and Moore, 1973, Aglaocrinus magnus (Strimple, 1949), and the columnal taxon Pentaridica pentagonalis Moore and Jeffords, 1968, provide new morphological infor- mation. Additional specimens of echinoid plates and spines have also been recovered from the Minturn Formation. They are assigned to Archaeocidaris ourayensis Girty, 1903, Archaeocidaris triplex White, 1881, and Archaeocidaris cratis White, 1876. These specimens come from three thin marine intervals that are overlain and underlain by coarse fluvial and marginal marine deposits. They were recovered from shale and limestone beds that interfinger with sandstone and shale beds. -
Ecomorphological and Taphonomic Gradients in Clypeasteroid
Ecomorphological and taphonomic gradients in clypeasteroid-dominated echinoid assemblages along a mixed siliciclastic-carbonate shelf from the early Miocene of northern Sardinia, Italy ANDREA MANCOSU and JAMES H. NEBELSICK Mancosu, A. and Nebelsick, J.H. 2017. Ecomorphological and taphonomic gradients in clypeasteroid-dominated echi- noid assemblages along a mixed siliciclastic-carbonate shelf from the early Miocene of northern Sardinia, Italy. Acta Palaeontologica Polonica 62 (3): 627–646. Clypeasteroid echinoids are widespread and abundant within Miocene sedimentary sequences of the Mediterranean area within both siliciclastic and carbonate deposits. Herein, three clypeasteroid-dominated echinoid assemblages from the mixed siliciclastic-carbonate succession of the Mores Formation (lower Miocene) cropping out within the Porto Torres Basin (northern Sardinia) are described. These assemblages were compared to previously described clypeasteroid-bear- ing deposits from the Miocene of northern Sardinia with the purpose of investigating their palaeoecology and taphon- omy along a shelf gradient. These goals are accomplished by various methods including (i) logging sedimentary facies, (ii) analysing the functional morphology of sea urchin skeletons, (iii) comparing the relative abundance of taxa and taphonomic features, and (iv) studying associated fauna, flora, and trace fossils. The clypeasteroid-bearing deposits differ greatly with respect to echinoid diversity, accompanying fauna and flora, sedimentological signatures, and taphonomic features. They also show variations in depositional environments and the mechanism of formation of the deposits. Three different shelf settings are distinguished: littoral, inner sublittoral, and outer sublittoral environments. Furthermore, an ecomorphological gradient along the shelf is recognized with respect to echinoid taxa and their morphologies. This gradient ranges from shallow water to a moderately deep shelf and is interpreted with respect to both abiotic and biotic factors as well as the taphonomy of the echinoid tests. -

MONGIARDINO KOCH & THOMPSON 12 Abstract 13 Several unique properties of echinoids (sea urchins) make them useful for exploring 14 macroevolutionary dynamics, including their remarkable fossil record that can be incorporated 15 into explicit phylogenetic hypotheses. However, this potential cannot be exploited without a 16 robust resolution of the echinoid tree of life. We revisit the phylogeny of crown group 17 Echinoidea using both the largest phylogenomic dataset compiled for the clade, as well as a 18 large-scale morphological matrix with a dense fossil sampling. -
