MoUusca, Polyplacophora, taxon list, bibliography ABSTRACT. This paper lists species-group names of Récent and fossil Polyplacophora (MoUusca) that were published after 1998 (for the Récent species) and 1987 (for the fossil species). A total of 171 species were since then introduced, of which 123 are attributed to valid fossil taxa and 48 to valid Récent taxa. The authorship and complète références are provided for each species-group name. INTRODUCTION Considerazioni suUa famiglia Leptochitonidae Dali, 1889 (MoUusca: Polyplacophora). III.

While the most advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the original submitted. The following explanation of techniques is provided to help you understand markings or patterns which may appear on this reproduction. 1.The sign or "target" for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pages to insure you complete continuity. 2. When an image on the film is obliterated with a large round black mark, it is an indication that the photographer suspected that the copy may have moved during exposure and thus cause a blurred image.

The majority are molluscan and this second part of a catalogue of these collections reviews the types for 14 chiton and two scaphopod species. It deals with seven primary types and 12 secondary type lots, which are split between 12 Recent taxa and four fossil taxa. All of the holotypes reviewed here have been illustrated.

  • Shell Microstructures in Early Cambrian Molluscs

    Shell Microstructures in Early Cambrian Molluscs

    Shell microstructures in Early Cambrian molluscs ARTEM KOUCHINSKY Kouchinsky, A. 2000. Shell microstructures in Early Cambrian molluscs. - Acta Palaeontologica Polonica 45,2, 119-150. The affinities of a considerable part of the earliest skeletal fossils are problematical, but investigation of their microstructures may be useful for understanding biomineralization mechanisms in early metazoans and helpful for their taxonomy. The skeletons of Early Cambrian mollusc-like organisms increased by marginal secretion of new growth lamel- lae or sclerites, the recognized basal elements of which were fibers of apparently aragon- ite. The juvenile part of some composite shells consisted of needle-like sclerites; the adult part was built of hollow leaf-like sclerites. A layer of mineralized prism-like units (low aragonitic prisms or flattened spherulites) surrounded by an organic matrix possibly existed in most of the shells with continuous walls. The distribution of initial points of the prism-like units on a periostracurn-like sheet and their growth rate were mostly regular. The units may be replicated on the surface of internal molds as shallow concave poly- gons, which may contain a more or less well-expressed tubercle in their center. Tubercles are often not enclosed in concave polygons and may co-occur with other types of tex- tures. Convex polygons seem to have resulted from decalcification of prism-like units. They do not co-occur with tubercles. The latter are interpreted as casts of pore channels in the wall possibly playing a role in biomineralization or pits serving as attachment sites of groups of mantle cells. Casts of fibers and/or lamellar units may overlap a polygonal tex- ture or occur without it.

STEBBINS 1,* and DOUGLAS J. EERNISSE 2 1 City of San Diego Marine Biology Laboratory, Metropolitan Wastewater Department, San Diego, CA, USA 2 Department of Biological Science, California State University, Fullerton, CA, USA Abstract: About 36 species of chitons possibly occur at depths greater than 30 m along the continental shelf and slope of the Southern California Bight (SCB), although little is known about their distribution or ecology. Nineteen species are reported here based on chitons collected as part of long-term, local benthic monitoring programs or less frequent region-wide surveys of the entire SCB, and these show little overlap with species that occur at depths typically encountered by scuba divers. Most chitons were collected between 30-305 m depths, although records are included for a few from slightly shallower waters. Of the two extant chiton lineages, Lepidopleurida is represented by Leptochitonidae (2 genera, 3 species), while Chitonida is represented by Ischnochitonidae (2 genera, 6-9 species) and Mopaliidae (4 genera, 7 species).

ABSTRACT First records of Callistochiton portobelensis Ferreira and Ischnochiton kaasi Ferreira (Mollusca: Polyplacophora) from the Colombian Caribbean. Callistochiton portobelensis Ferreira 1976 and Ischnochiton kaasi Ferreira, 1987 are reported for the first time from the Colombian Caribbean. Both species were found in shallow water, under rocks, at Santa Marta in October 2009 . KEY WORDS: Mollusca, Polyplacophora, Records, Caribbean, Colombia . Las especies de quitones (Mollusca: Polyplacophora) previamente documentados para la costa del Caribe colombiano son 22 (Götting, 1973; Díaz y Puyana, 1994, Gracia et al., 2005, 2008) . Götting (1973) registró las primeras 10 especies: Ischnochiton limaciformis (Sowerby, 1832); Ischnochiton floridanus Pilsbry, 1892; Acanthochitona rhodea (Pilsbry, 1893); Ischnochiton pectinatus (Sowerby, 1840); Ceratozona rugosa (Sowerby, 1840); Chiton tuberculatus Linné, 1758; Chiton marmoratus Gmelin 1791; Acanthopleura granulata (Gmelin, 1791), Ischnochiton striolatus (Gray, 1828) y Lepidopleurus pergranatus (Dall, 1889); los ejemplares de esta última fueron posteriormente reasignados bajo L.

Dornbos, Department of Earth Sciences, University of Southern California, Los Angeles, CA 90089-0740, [email protected] ABSTRACT The broad marine ecological settings prevalent during the late Neo- proterozoic–early Phanerozoic (600–500 Ma) interval of early metazoan body plan origination strongly impacted the subsequent evolution and development of benthic metazoans. Recent work demonstrates that late Neoproterozoic seafloor sediment had well-developed microbial mats and poorly developed, vertically oriented bioturbation, thus producing fairly stable, relatively low water content substrates and a sharp water-sediment interface. Later in the Cambrian, seafloors with microbial mats became increasingly scarce in shallow-marine environments, largely due to the evolution of burrowing organisms with an increasing vertically oriented component to their bioturba- tion. The evolutionary and ecological effects of these substrate changes on Figure 1. Looping and meandering trace fossil Taphrhelminthopsis, made by a large Early Cambrian benthic metazoans, referred to as the bioturbator, on a bedding plane from Lower Cambrian Poleta Formation, White-Inyo Mountains, California. Such traces, consisting of a central trough between lateral ridges, occur in sandstones Cambrian substrate revolution, are deposited in shallow-marine environments.

SKOVSTED1 5 6 1Department of Palaeobiology, Swedish Museum of Natural History, P.O. Box 50007, 7 SE-104 05, Stockholm, Sweden. 8 2Palaeoecosystems Group, Department of Earth Sciences, Durham University, Durham 9 DH1 3LE, UK. 10 11 Mobergellans were one of the first Cambrian skeletal groups to be recognized yet have 12 long remained one of the most problematic in terms of biological function and affinity. 13 Typified by a disc-shaped, phosphatic sclerite the most distinctive character of the 14 group is a prominent set of internal scars, interpreted as representing sites of former 15 muscle attachment. Predominantly based on muscle scar distribution, mobergellans 16 have been compared to brachiopods, bivalves and monoplacophorans, however a 17 recurring theory that the sclerites acted as operculum remains untested. Rather than 18 correlate the number of muscle scars between taxa, here we focus on the percentage of 19 the inner surface shell area that the scars constitute. We investigate two mobergellan 20 species, Mobergella holsti and Discinella micans comparing the Cambrian taxa with the 21 muscle scars of a variety of extant and fossil marine invertebrate taxa to test if the 22 mobergellan muscle attachment area is compatible with an interpretation as operculum. 23 The only skeletal elements in our study with a comparable muscle attachment 24 percentage are gastropod opercula. Complemented with additional morphological 25 information, our analysis supports the theory that mobergellan sclerites acted as an 26 operculum presumably from a tube-living organism.

Il doit être un outil de travail permettant de trouver rapidement les principaux travaux qui existent sur chaque sujet. Nous avons tenté de rendre ce document exhaustif; pour cette raison nous avons cité certains articles de presse, les rapports ronéotypés dont certains ont été tirés à très peu d'exemplaires et sont quasiment introuvables; ils constituent la "littérature grise" et peuvent s'avérer parfois très utiles. Les documents bibliographiques existants ont été largement utilisés : O'REILLY, 1955; PISIER, 1982 ; Bulletin Technique n° 5 du CCOP/SOPAC ainsi que certains documents tels que THOMASSIN (1981) et RICHER de FORGES et al.
