  • Fossil Polychaetes from the Upper Cretaceous Rock Formations of South India—
    FOSSIL POLYCHAETES FROM THE UPPER CRETACEOUS ROCK FORMATIONS OF SOUTH INDIA--PART II BY G. W. CHIPLONKAR AND P. M. TAPASWI (Maharashtra Association for the Cultivation of Science, Poona-4) Received October 29, 1972 (Communicated by Prof. T.S. Mahabale) ABSTRACT Eight polychaetan species are described here, three of which, viz., Burtinella concava (Sow.), Tubulostium eallosum Stol. T. discoidium Stol., described by Stoliczka as gastropod species, are now transferred to the Polyehaeta in the light of new information. Among the three species described here as new to science, one has for its proper placement, necessitated creation of the now genus, viz., Rotulispira falling under the subfamily Spirorbinae Chamborlin. Spirorbula Nielsen is repotted for the first time from South Indian Cretaceous. Family Terebellidae Grube represented by Terebellolites Desio, a heterogenous group, is also recorded for the first time from these deposits. INTRODUCTION IN the present communication eight more (Chiplonkar and Tapaswi, 1973, Pt. I) polychaetan species are described. As mentioned in Part I, we have followed, except where otherwise indicated, Regenhardt (1961) in his classification of the Serpulidae.

  • Biomineralization of Polychaete Annelids in the Fossil Record
    minerals Review Biomineralization of Polychaete Annelids in the Fossil Record Olev Vinn Department of Geology, University of Tartu, Ravila 14A, 50411 Tartu, Estonia; [email protected]; Tel.: +372-5067728 Received: 31 August 2020; Accepted: 25 September 2020; Published: 29 September 2020 Abstract: Ten distinct microstructures occur in fossil serpulids and serpulid tubes can contain several layers with different microstructures. Diversity and complexity of serpulid skeletal structures has greatly increased throughout their evolution. In general, Cenozoic serpulid skeletal structures are better preserved than Mesozoic ones. The first complex serpulid microstructures comparable to those of complex structures of molluscs appeared in the Eocene. The evolution of serpulid tube microstructures can be explained by the importance of calcareous tubes for serpulids as protection against predators and environmental disturbances. Both fossil cirratulids and sabellids are single layered and have only spherulitic prismatic tube microstructures. Microstructures of sabellids and cirratulids have not evolved since the appearance of calcareous species in the Jurassic and Oligocene, respectively. The lack of evolution in sabellids and cirratulids may result from the unimportance of biomineralization for these groups as only few species of sabellids and cirratulids have ever built calcareous tubes. Keywords: biominerals; calcite; aragonite; skeletal structures; serpulids; sabellids; cirratulids; evolution 1. Introduction Among polychaete annelids, calcareous tubes are known in serpulids, cirratulids and sabellids [1–3]. The earliest serpulids and sabellids are known from the Permian [4], and cirratulids from the Oligocene [5]. Only serpulids dwell exclusively within calcareous tubes. Polychaete annelids build their tubes from calcite, aragonite or a mixture of both polymorphs. Calcareous polychaete tubes possess a variety of ultrastructural fabrics, from simple to complex, some being unique to annelids [1].

The probable sources of these sediments were generated in Carboniferous to Early Paleogene times (,315 to 60 Ma). The total depths of individual James Ross Basin formations are discussed. The AFT data were modelled, and the thermal history model was reconstructed for samples from Seymour Island. The first stage after a period of total thermal annealing (when the samples were above 1208C) involved Late Triassic cooling (,230 to 200 Ma) and is followed by a period of steady cooling through the whole apatite partial annealing zone (PAZ, 60–1208C) to minimum temperature in Paleocene/Early Eocene. The next stage was the maximum burial of sedimentary rocks in the Eocene (,35 Ma, 1.1–1.8 km) and the final cooling and uplift of Seymour Island sedimentary rocks at ,35 to 20 Ma.

A total of 250 samples were sys- tematically collected within these profiles at approximately 10- meter intervals. Good weather and invaluable support from the CARLOS MACELLARI and BRIAN T.

  • Notopus Dorsipes (Linnaeus) in Singapore: First Record of the Brachyuran Superfamily Raninoidea (Crustacea: Decapoda) on the Sunda Shelf
    NATURE IN SINGAPORE 2012 5: 19–25 Date of Publication: 27 January 2012 © National University of Singapore NOTOPUS DORSIPES (LINNAEUS) IN SINGAPORE: FIRST RECORD OF THE BRACHYURAN SUPERFAMILY RANINOIDEA (CRUSTACEA: DECAPODA) ON THE SUNDA SHELF Martyn E.

This represents the first record of the superfamily Raninoidea de Haan, 1839, in Singapore and on the Sunda Shelf (Figs. 1, 2). The superfamily Raninoidea has a worldwide distribution and its members inhabit marine habitats from the intertidal zone to over 300 m deep (reviewed in Ahyong et al., 2009; see also Dawson & Yaldwyn, 1994). Fifty species of raninoids are currently assigned to 12 genera in six subfamilies (Ng et al., 2008). Notopus dorsipes belongs to a monotypic genus currently assigned to the subfamily Notopodinae Serène & Umali, 1972 (see Ng et al., 2008). Originally described as Cancer dorsipes by Linnaeus (1758), this species has had a confused nomenclatural history (see Holthuis, 1962). In order to stabilise the name Cancer dorsipes Linnaeus, Holthuis (1962: 55) designated a figure in Rumphius (1705: pl. 10: Fig. 3) as the lectotype of Notopus dorsipes (reproduced as Fig. 3). De Haan (1841) established the genus Notopus for Cancer dorsipes Linnaeus, the type species by monotypy.
