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]. -

Around 1,500 living species of starfish occur on the seabed in all the world's oceans, from the tropics to subzero polar waters. They are found from the intertidal zone down to abyssal depths, 6,000m below the surface. Starfish typically have a central disc and five arms, though some species have a larger number of arms. The aboral or upper surface may be smooth, granular or spiny, and is covered with overlapping plates. -

The study of the Portuguese marine ichthyofauna has a long historical tradition, rooted back in the 18th Century. Here we present an annotated checklist of the marine fishes from Portuguese waters, including the area encompassed by the proposed extension of the Portuguese continental shelf and the Economic Exclusive Zone (EEZ). The list is based on historical literature records and taxon occurrence data obtained from natural history collections, together with new revisions and occurrences. -

Carnets de Géologie / Notebooks on Geology - Letter CG2011/05 (CG2011_L05) Evolution of a dense outer protective tube layer in serpulids (Polychaeta, Annelida) 1 Olev VINN 2 Elena K. KUPRIYANOVA Abstract: Although the walls of most serpulid tubes are homogeneous, tubes of certain species may contain up to four ultrastructurally distinct layers. Some of these layers are made of densely packed large crystals and others are composed of sparsely packed fine crystals. In almost all (16 of 17) examined species having layered tubes, the dense layer is located in the outer wall part and the layer(s) composed of fine and relatively sparsely packed crystals are positioned in the inner wall part. Two species have transparent tube walls made entirely of densely packed crystals. Fossil serpulid tubes with dense outer layers (DOL) are known from the Late Cretaceous (Pentaditrupa subtorquata) and the Eocene (Pyrgopolon cf. mellevillei and Rotularia spirulaea). DOL gives a characteristic smooth shiny appearance to the tube surface and presumably evolved as an adaptation against drilling predation by gastropods and to delay shell dissolution in the waters of the deep-sea under-saturated with calcium carbonate. Key Words: Serpulidae; biomineralization; tube ultrastructure; evolution. Citation : VINN O. & KUPRIYANOVA E.K.
