Echinoidea Clypeasteroidea
Biodiversity Journal, 2014, 5 (2): 291–358 Analysis of some astriclypeids (Echinoidea Clypeast- eroida) Paolo Stara1* & Luigi Sanciu2 1Centro Studi di Storia Naturale del Mediterraneo - Museo di Storia Naturale Aquilegia, Via Italia 63, Pirri-Cagliari and Geomuseo Monte Arci, Masullas, Oristano, Sardinia, Italy; e-mail: [email protected] *Corresponding author The systematic position of some astriclypeid species assigned through times to the genera Amphiope L. Agassiz, 1840 and Echinodiscus Leske, 1778 is reviewed based on the plating ABSTRACT pattern characteristics of these two genera universally accepted, and on the results of new studies. A partial re-arrangement of the family Astriclypeidae Stefanini, 1912 is herein pro- posed, with the institution of Sculpsitechinus n. g. and Paraamphiope n. g., both of them char- acterized by a peculiar plating-structure of the interambulacrum 5 and of the ambulacra I and V. Some species previously attributed to Amphiope and Echinodiscus are transferred into these two new genera. Two new species of Astriclypeidae are established: Echinodiscus andamanensis n. sp. and Paraamphiope raimondii n. sp. Neotypes are proposed for Echin- odiscus tenuissimus L. Agassiz, 1840 and E. auritus Leske, 1778, since these species were still poorly defined, due to the loss of the holotypes and, for E. auritus, also to the unclear geographical/stratigraphical information about the type-locality. A number of additional nom- inal fossil and extant species of "Echinodiscus" needs revision based on the same method.

W. DROOGER In the July issue of The Micropaleontologist, Esteban Boltovskoy raised the question of the species concept and related problems in the study of foramninifera. His article clearly shows the disadvantages of space limitations, as it deals with so many topics that the schematic treatment is sometimes in danger of being misunderstood. Nevertheless, Boltovskoy's article may be very usef'ul for those who ignore the neonto- logical species and subspecies concepts. Some very valuable warnings are given, although their background has to be necessarily very vague. At the risk of being equally terse, I would like to comment on some of the points raised by Boltovskoy. -
SI Appendix for Hopkins, Melanie J, and Smith, Andrew B
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. -
Glossary of Major Terms and Concepts
Glossary of Major Terms and Concepts The following terms and concepts form the core of much of this book. Generally, they appear in boldface type in the text. The chapters in which they are more fully discussed are also given. Acceleration: Faster rate of developmenral evenrs (at any level: cell, organ, individual) in the descendanr; produces peramorphie traits when expressed in the adult pheno type. (Chapters 1 and 2) Allometric heterochrony: Change in a trair as a function of size (as opposed to a function of age in " true" heterochrony); it is useful as adescriptor and can be inrerpretive considering that body size is often a beuer metric of " inrrinsic" age than chronologi cal age. The same categories apply as in " true" heterochrony, only the adjective "allometric" is prefixed: e.g. , " allometric progenesis" is when the descendant ter minates growth at a smaller size (as opposed to age) than the ancestor. (Chapter 2) Allometry: The study of size and shape, usually using biometrie data; the change in size and shape observed. Basic kinds of allometric change include the following. Com plex allometry: occurs when the ratio of the specific growth rates of the traits compared are not constant, a log-log plot comparing the traits will not yield a straight line (i.e., " k" in the allometric formula is inconstanr). Isometry: occurs when there is no change in shape with size increase; that is, when the traits being compared on a log-log plot yield a straight line with a slope (k in the allometric formula) that is effectively equal to 1. -

The member has yielded a rich echinoid fauna and 21 species of Echinoid belonging to 14 genera are recognized and described. The Kabir Kuh section yielded two regular echinoid taxa: Salenia nutrix and Goniopygus superbus, one holectypoid taxa: Coptodiscus noemiae, two conulid taxa: Conulus douvillei and Globator bleicheri, six cassiduloid taxa: Parapygus longior, Parapygus declivis, Parapygus inflatus, Parapygus vassilini, Vologesia tataosi and Pygurostoma morgani, one holasteroid species: Hemipneustes persicus and nine spatangoid taxa: Iraniaster douvillei, I. morgani, I. nodulosus, Hemiaster noemiae, Hemiaster opimus, Mecaster kanepanensis, Mecaster longus, Proraster morgani and Epiaster lamberti. The taxon association indicates a Campanian age. Some of the taxa are known from the similar Campanian age in Saudi Arabia such as: Coptodiscus noemiae. Some specimens are reported also from Campanian deposits of Afghanistan such as: Hemiaster noemiae, H. opimus and Parapygus vassilini. Globator bleicheri and Salenia nutrix are recorded from Maastrichtian deposits of UAE and Oman. Keywords: Campanian, Echinoid, Kabir Kuh, Seymareh member, Southwest Iran. Introduction Acropeltidae, Holectypidae, Conulidae, Cassiduloida Echinoids are among the most conspicuous and , Holasteroid and Spatangoida. -

Enric Forner1, Txema Moreno2 Resumen Se describe una especie nueva del género Leptosalenia Smith & Wright, 1990 con material pro- cedente del Albiense de la sierra de Aralar (Nafarroa), de la cuenca Vasco-Cantábrica: L. botanzi sp. nov. Se revisan las diferencias entre todas las especies del genero Leptosalenia entre el Ap- tiense y el Cenomaniense. L. botanzi es grande para el género, alta, con largas fosetas suturales perpendiculares a las líneas de sutura entre las placas del sistema apical y apuntando hacia los gonoporos; la placa suranal es de menor tamaño que el periprocto; tiene 4 tubérculos princi- pales por serie en los interambulacros. La especie nueva se ha encontrado junto a una abun- dante fauna de braquiópodos, lo que implicaría una salinidad marina normal, y diversidad de corales, de la que se puede deducir una profundidad moderada. De hecho el yacimiento está muy cerca de importantes arrecifes fósiles de la misma edad, lo que quizás indicaría un mar de poca profundidad y, es muy posible, que con cierta protección del mar abierto. Esta es la tercera especie de Leptosalenia registrada en la cuenca Vasco-Cantabrica; las otras dos son L. prestensis (Desor, 1856) y L. -
