The type species of the genera Cassiope and Paraglauconia are verified and described. Seven species of British Lower Cretaceous Cassiopidae (Mesogastropoda, Cerithiacea?) are redescribed and figured: Gymnentome pizcuetana, Paraglauconia tricarinata, P. lujani, P.fittoni, P. shipbornemis, Meso- glauconia arkelli, M. renevier'. Their generic assignments are examined and the significance of their stratigraphical occurrence established. The geological history of the family is reviewed. By comparison with the ecology of Recent Cerithiacea, the evidence of associated faunas indicates a probable marine estuarine or mangal-like habitat for the Cassiopidae. The European palaeogeographical distribution of the family is briefly considered. Introduction The occurrence of the Cassiopidae is readily accepted as an indicator of a particular ecological environment. They are relatively common in intertidal environments of Pan-Tethyan, or 'non- boreal', Cretaceous deposits. Akopyan (1976: 131) believed that their distribution, although relatively widespread, was facies controlled. As discussed below (p. 274) brackish water affinities have been attributed to them (Casey 1961: 516), but examination of their faunal associations has established that the majority are marine (Simpson 1983; Mennessier 1984 : 102; Cleevely et al. 1984; Kase 1984: 119). According to Morter (1984), the cassiopids form part of one of the typical molluscan associations occurring during the periodic marine incursions of the Weald and Wessex Basins during the Lower Cretaceous. Their frequent association with lignitiferous deposits (see Coquand, 1865; Aguiular et al. 1971) has led Mennessier to argue that such deposits might well indicate the proximity of a mangrove environment. Our interpretation (Cleevely et al. 1984) of the Lower Cretaceous Punfield Marine Band fauna of Dorset (and of a flora that provides no evidence of mangrove species; p. 102) is that it is from an estuarine or in-shore situation. Mennessier also postulated that it was their lower oxygen requirements (i.e. lower than those of other gastropods of a comparable size) that had enabled the cassiopids to exploit such habitats, rather than any difference in their salinity tolerances. The description of these turriculate-conical gastropods, in which ornament is extremely variable, has resulted in considerable taxonomic confusion, largely because of their division into innummerable species which have then frequently been misinterpreted. The work of Akopyan (1976) on the rich, well-preserved late Cretaceous examples of the many genera of Cassiopidae found in Armenia has made a major contribution towards understanding this family. Mennessier (1984), on the other hand, although providing a world-wide compilation of all Cretaceous cassiopids, has produced an essentially phenetic and geographically-based classi- fication. Our disinclination to adopt his latter classification has prompted this account of the cassiopid species found in the British Cretaceous. It was also decided to publish the various translations of descriptions made available to us in an attempt to assist interpretation of significant species and stabilize their nomenclature. Records in England and earlier work This attempt to clarify the occurrences of cassiopids in the British Cretaceous formations has necessarily been restricted to known examples in museum collections. Many of their original localities are no longer accessible. The species that do occur are restricted to the Lower Cretaceous formations of southern England. Mantell (1833) provided the first record of a cassiopid species in Britain when he figured 'several shells ... found in ... the slabs at Pounceford' (1833: 249, fig. 3). However, that figure cannot be recognized as the tricarinata of J. de C. Sowerby subsequently described in Fitton (1836): see p. 259. The specimen was supposedly from the Wealden Shales at Punfield, near Swanage, Dorset, but Arkell (1941: 120) believed it to have come from the Purbeck locality of Pounceford, near Battle, Sussex (originally mentioned by Mantell) following his own compari- sons with other material from there. 1 CASSIOPIDAE 235 Table 1 The stratigraphical occurrence of species of Cassiopidae in Britain.

Present address: The Kyoto University Museum, Yoshida Honmachi, Sakyo-ku, Kyoto 606-8501, Japan (email: [email protected]) Received December 19, 2005; Revised manuscript accepted May 26, 2006 Abstract. Cerithiform gastropods possess high-spired shells with small apertures, anterior canals or si- nuses, and usually one or more spiral rows of tubercles, spines or nodes. This shell morphology occurs mostly within the superfamily Cerithioidea. Several morphologic characters of cerithiform shells are adap- tive within five broad functional areas: (1) defence from shell-peeling predators (external sculpture, pre- adult internal barriers, preadult varices, adult aperture) (2) burrowing and infaunal life (burrowing sculp- tures, bent and elongated inhalant adult siphon, plough-like adult outer lip, flattened dorsal region of last whorl), (3) clamping of the aperture onto a solid substrate (broad tangential adult aperture), (4) stabilisa- tion of the shell when epifaunal (broad adult outer lip and at least three types of swellings located on the left ventrolateral side of the last whorl in the adult stage), and (5) righting after accidental overturning (pro- jecting dorsal tubercles or varix on the last or penultimate whorl, in one instance accompanied by hollow ventral tubercles that are removed by abrasion against the substrate in the adult stage). Most of these char- acters are made feasible by determinate growth and a countdown ontogenetic programme.

    GEOLOGICAL GROUP, IPSWICH. JULY 1969 BULLETIN No. 6. ------------------------------------------------------------------------------- FIELDTRIP TO CORNWALL AND SOUTH DEVON, SEPTEMBER 1968. The primary object of the fieldtrip to Cornwall and South Devon on 14-19 September1968 was to visit the St. Erth Beds (near Hayle, Cornwall), the fauna of which is probably of Crag age (s.l.). Two members had visited the site on a previous occasion. Informal discussions were held and it was decided to travel by van and to camp at our destination. Two vans (a 15-cwt. and a 5-cwt.) were available and tents and cooking equipment were hired from the Ipswich Education Office (Mr. Britten of their staff was most helpful), supplemented by members equipment. A meeting was held a few days before departure, and members were given the itinerary and a list of personal and domestic items thought desirable. Each person was also required to bring a certain amount of food, e,g. jam, baked beans, butter, sugar, tinned meat - this was given with enough generosity that our estimated food bills were to be cut considerably. A tent- pitching practise was held the day before leaving. Nine people (Messrs. C. Garrod, P. Grainger, T. Jones, S. MacFarlane and R. Markham, and the Misses P. Cresswell M. Daniels, S. Giles, and L. Hyde) formed the final party. Their equipment was collected some hours before departure, and participants met in the town centre, that the vans could leave Ipswich at 11p.m. on Saturday 14 September. After driving through the night, Sunday breakfast was obtained in Salisbury, before pressing on to Okehampton and our first geological stop.

  • SURVEY of the LITERATURE on RECENT SHELLS from the RED SEA (Second Enlarged and Revised Edition)
    TRITON 24 SEPTEMBER 2011 SUPPLEMENT 1 SURVEY OF THE LITERATURE ON RECENT SHELLS FROM THE RED SEA (second enlarged and revised edition) L.J. van Gemert *) Abstract: About 2,100 references are listed in the survey. Shells are being considered here as shell-bearing mollusks of the Gastropoda, Bivalvia and Scaphopoda. And the region covered is not only the Red Sea, but also the Gulf of Aden, including Somalia, and the Suez Canal, including Lessepsian species. Literature on fossils finds, especially from the Pliocene, Pleistocene and Holocene, is listed too. Introduction My interest in recent shells from the Red Sea dates from about 1996. Since then, I have been, now and then, trying to obtain information on this subject. Recently I decide to stop gathering information in a haphazard way and to do it more properly. This resulted in a survey of approximately 1,420 references (Van Gemert, 2010). Since then, this survey has been enlarged considerably and contains now approximately 2,100 references. They are presented here. Scope In principle every publication in which mollusks are reported to live or have lived in the Red Sea should be listed in the survey. This means that besides primary literature, i.e. articles in which researchers are reporting their finds for the first time, secondary and tertiary literature, i.e. reviews, monographs, books, etc are to be included too. These publications were written not only by a wide range of authors ranging from amateur shell collectors to profesional malacologists but also by people interested in other fields. This implies that not only malacological journals and books should be considered, but also publications from other fields or disciplines, such as environmental pollution, toxicology, parasitology, aquaculture, fisheries, biochemistry, biogeography, geology, sedimentology, ecology, archaeology, Egyptology and palaeontology, in which Red Sea shells are mentioned.

  • Covering All Continues Above the Marine Deposits of the Tremp
    LEIDSE GEOLOGISCHE MEDEDELINGEN, Deel 51, Aflevering 2, pp. 151-231, 16-11-1978 Biostratigraphy, palaeoecology and palaeogeography of the mainly marine Ager Formation (Upper Paleocene — Lower Eocene) in the Tremp Basin, Central-South Pyrenees, Spain BY Pieter A.M. Gaemers Summary with axial During the greater part of the Palaeogene the Tremp Basin was an area which underwent rapid subsidence as compared the zone of the Pyrenees to the north, and the Ebro Massif to the south. As a result the sea occupied this area for a long time and deposition of the Ager Formation took place during the Late Paleocene and Early Eocene in a bay forming an appendix of the Atlantic Ocean. At the maximum of the transgression probably a connection with the Tethys existed. During this entire development the Tremp subsidence. Basin was tectonically separated from the more southerly Ager Basin by the Montsech High which underwent much less The southern side of the Tremp Basin, under the influence of this high, subsided less rapidly than the central part. This resulted in a much considerably thinner succession along the southern side, consisting mainly of limestones, and a thicker pile in the central part side of the basin for have been eroded. Where mainly built up of marls. Sediments deposited along the northern a greater part they have been preserved, they are less limy than those along the southern side. The northern margin moved in the course of time in northern or southern direction, in contrast to the stable Montsech High which formed a stationary southern margin. The correlations within the formation are based on alveolinids and on lithostratigraphical characteristics.
