By Frederick Chapman, A.L.S., F.G.S., Commonwealth Palaeon- tologist, and Francis A. Cudmore, Hon. Palaeontologist, National Museum. Plates XII-XV. Nearly 60 years ago Professor P. M. Duncan described the first Australian Cainozoic cidaroid before the Geological Society of London. During the next 20 years Professors R. Tate and J. W. Gregory published references to our fossil cidaroids, but further descriptive work was not attempted until the present authors undertook to examine the accumulated material in the National Museum, the Tate Collection at Adelaide University Museum, the Commonwealth Palaeontological Collection, and the private collections made by the late Dr. T. S. Hall, F. A. Singleton, the Rev. Geo. Cox and the authors. The classification of the Cidaridae is founded mainly upon living species and it is partly based on structures which are only rarely preserved in fossils. Fossil cidaroid tests are usually imperfect. On abraded tests the conjugation of ambulacral pores is obscure. The apical system is preserved only in one specimen among those examined. The spines are rarely attached to the test and pedicellariae are wanting. Therefore, in dealing with our specimens we have been guided mainly by the appear- ance and structure of ambulacral and interambulacral areas. Certain features used in our classification vary with the growth stage of the test : for instance, the number of coronal plates in vertical series, the number of ambulacral plates adjacent to the largest coronal plate, and sometimes the number of granules on the inner end of ambulacral plates. -

Aceptado 04-XI-2014. Abstract: Taxonomy and ecologic biogeography of the irregular Echinoids (Echinoidea: Irregularia) from Mexico. Mexico owns 643 species of echinoderms, almost 10% of the known echinoderm species in the planet. Its geographic location -between the oceanic influences of the Western Central Atlantic and the Eastern Central Pacific- largely explains its enormous biological and ecological diversity. Research on echinoderms in Mexico began in the late nineteenth century; however, there are no reviews on its irregular echinoids. This work reviews the taxonomic and geographic information of irregular echinoids from Mexico, housed in four collections: 1) Colección Nacional de Equinodermos “Ma. Elena Caso Muñoz” from the Instituto de Ciencias del Mar y Limnología (ICML), Universidad Nacional Autónoma de México (UNAM); 2) Invertebrate Zoology Collection, Smithsonian Museum of Natural History, Washington, D.C., United States of America (USA); 3) Invertebrate Collection, Museum of Comparative Zoology, University of Harvard, Boston, Massachusetts, USA and 4) Invertebrate Zoology, Peabody Museum, Yale University, New Haven, Connecticut, USA. -

Hopkins and Smith, SI Appendix SI Appendix for Hopkins, Melanie J, and Smith, Andrew B. Dynamic evolutionary change in post-Paleozoic echinoids and the importance of scale when interpreting changes in rates of evolution. Corrections to character matrix Before running any analyses, we corrected a few errors in the published character matrix of Kroh and Smith (1). Specifically, we removed the three duplicate records of Oligopygus, Haimea, and Conoclypus, and removed characters C51 and C59, which had been excluded from the phylogenetic analysis but mistakenly remain in the matrix that was published in Appendix 2 of (1). We also excluded Anisocidaris, Paurocidaris, Pseudocidaris, Glyphopneustes, Enichaster, and Tiarechinus from the character matrix because these taxa were excluded from the strict consensus tree (1). This left 164 taxa and 303 characters for calculations of rates of evolution and for the principal coordinates analysis. Other tree scaling methods The most basic method for scaling a tree using first appearances of taxa is to make each internal node the age of its oldest descendent ("stand") (2), but this often results in many zero-length branches which are both theoretically questionable and in some cases methodologically problematic (3). Several methods exist for modifying zero-length branches. In the case of the results shown in Figure 1, we assigned a positive length to each zero-length branch by having it share time equally with a preceding, non-zero-length branch (“equal”) (4). However, we compared the results from this method of scaling to several other methods. First, we compared this with rates estimated from trees scaled such that zero-length branches share time proportionally to the amount of character change along the branches (“prop”) (5), a variation which gave almost identical results as the method used for the “equal” method (Fig. -

Fossil Spatangoid Echinoids of Cuba
SMITHSONIAN CONTRIBUTIONS TO PALEOBIOLOGY • NUMBER 55 Fossil Spatangoid Echinoids of Cuba Porter M. Kier SMITHSONIAN INSTITUTION PRESS City of Washington 1984 ABSTRACT Kier, Porter M. Fossil Spatangoid Echinoids of Cuba. Smithsonian Contributions to Paleobiology, number 55, 336 pages, frontispiece, 45 figures, 90 plates, 6 tables, 1984.—The fossil spatangoid echinoids of Cuba are described based for the most part on specimens in the Sanchez Roig Collection. Seventy-nine species are recognized including 10 from the Late Cretaceous, 36 from the Eocene, 20 from the Oligocene-Miocene, 11 from the Miocene, and 2 of uncertain age. Three of the Eocene species are new: Schizas ter forme III, Linthia monteroae, and Antillaster albeari. A new genus of schizasterid is described, Caribbaster, with the Eocene Prenaster loveni Cotteau as the type-species. A new Asterostoma, A. pawsoni, is described from the Eocene of Jamaica. The Eocene age of the Cuban echinoid-bearing localities is confirmed by the presence outside Cuba of many ofthe same species in beds dated on other fossils. Some evidence supports the Miocene determinations, but the echinoids are of little assistance in resolving the question whether the Cuban beds attributed to the Oligocene are Oligocene or Miocene. Cuban, and in general, the Caribbean Tertiary echinoid faunas are distinct from those in Europe and the Mediterranean. Many genera are confined to the Caribbean. The Cuban fauna is also different from that found nearby in Florida. This difference may be due to a suggested greater depth of water in Cuba. Se describen los equinoideos espatangoideos de Cuba, incluyendo los es- pecimenes de la Coleccion Sanchez Roig. -

However, to establish sustainable conservation areas, understanding species and communities distribution patterns is critical. For this purpose, the ecoregionalization approach can prove useful by identifying spatially explicit and well-delimited regions of common species composition and environmental settings. Such regions are expected to have similar biotic responses to environmental changes and can be used to define priorities for the designation of Marine Protected Areas. In the present work, a benthic ecoregionalization of the Southern Ocean is proposed based on echinoids distribution data and abiotic environmental parameters. Echinoids are widely distributed in the Southern Ocean, they are tax- onomically and ecologically well diversified and documented. Given the heterogeneity of the sampling effort, predictive spatial models were produced to fill the gaps in between species distribution data. -

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. -
Biodiversidad De Los Equinodermos (Echinodermata) Del Mar Profundo Mexicano
Biodiversidad de los equinodermos (Echinodermata) del mar profundo mexicano Francisco A. Solís-Marín,1 A. Laguarda-Figueras,1 A. Durán González,1 A.R. Vázquez-Bader,2 Adolfo Gracia2 Resumen Nuestro conocimiento de la diversidad del mar profundo en aguas mexicanas se limita a los escasos estudios existentes. El número de especies descritas es incipiente y los registros taxonómicos que existen provienen sobre todo de estudios realizados por ex- tranjeros y muy pocos por investigadores mexicanos, con los cuales es posible conjuntar algunas listas faunísticas. Es importante dar a conocer lo que se sabe hasta el momen- to sobre los equinodermos de las zonas profundas de México, información básica para diversos sectores en nuestro país, tales como los tomadores de decisiones y científicos interesados en el tema.
