CEPHALOPODS 688 Cephalopods
click for previous page CEPHALOPODS 688 Cephalopods Introduction and GeneralINTRODUCTION Remarks AND GENERAL REMARKS by M.C. Dunning, M.D. Norman, and A.L. Reid iving cephalopods include nautiluses, bobtail and bottle squids, pygmy cuttlefishes, cuttlefishes, Lsquids, and octopuses. While they may not be as diverse a group as other molluscs or as the bony fishes in terms of number of species (about 600 cephalopod species described worldwide), they are very abundant and some reach large sizes. Hence they are of considerable ecological and commercial fisheries importance globally and in the Western Central Pacific. Remarks on MajorREMARKS Groups of CommercialON MAJOR Importance GROUPS OF COMMERCIAL IMPORTANCE Nautiluses (Family Nautilidae) Nautiluses are the only living cephalopods with an external shell throughout their life cycle. This shell is divided into chambers by a large number of septae and provides buoyancy to the animal. The animal is housed in the newest chamber. A muscular hood on the dorsal side helps close the aperture when the animal is withdrawn into the shell. Nautiluses have primitive eyes filled with seawater and without lenses. They have arms that are whip-like tentacles arranged in a double crown surrounding the mouth. Although they have no suckers on these arms, mucus associated with them is adherent. Nautiluses are restricted to deeper continental shelf and slope waters of the Indo-West Pacific and are caught by artisanal fishers using baited traps set on the bottom. The flesh is used for food and the shell for the souvenir trade. Specimens are also caught for live export for use in home aquaria and for research purposes. -

We compiled detailed information on 252 occurrences of belemnites in six National Park Service (NPS) areas in Alaska. This information was based on published literature and maps, unpublished U.S. Geological Survey internal fossil reports (“Examination and Report on Referred Fossils” or E&Rs), the U.S. Geological Survey Mesozoic locality register, the Alaska Paleontological Database, the NPS Paleontology Archives and our own records of belemnites found in museum collections. Few specimens have been identified and many consist of fragments. However, even these suboptimal specimens provide evidence that belemnites are present in given formations and provide direction for future research. Two especially interesting avenues for research concern the time range of belemnites in Alaska. Belemnites are known to have originated in what is now Europe in the Early Jurassic Hettangian and to have a well-documented world-wide distribution in the Early Jurassic Toarcian. -

Belemnite Extinction and the Origin of Modern Cephalopods 35 M.Y. Prior to the Cretaceous−Paleogene Event
Belemnite extinction and the origin of modern cephalopods 35 m.y. prior to the Cretaceous−Paleogene event Yasuhiro Iba1,2*, Jörg Mutterlose1, Kazushige Tanabe3, Shin-ichi Sano4, Akihiro Misaki5, and Kazunobu Terabe6 1Institut für Geologie, Mineralogie und Geophysik, Ruhr-Universität Bochum, 44801, Germany 2Department of Geology and Paleontology, National Museum of Nature and Science, Tokyo 169-0073, Japan 3Department of Earth and Planetary Science, University of Tokyo, Tokyo 113-0033, Japan 4Fukui Prefectural Dinosaur Museum, Fukui 911-8601, Japan 5Kitakyushu Museum of Natural History and Human History, Fukuoka 805-0071, Japan 6Arabian Oil Company, Ltd., Tokyo 140-0002, Japan ABSTRACT determination of the strata studied is based on Belemnites, a very successful group of Mesozoic cephalopods, fl ourished in Cretaceous diagnostic ammonite species. Evaluations of oceans until the Cretaceous−Paleogene event, when they became globally extinct. Following museum collections (Mikasa City Museum, and this event the modern types of cephalopods (squids, cuttlefi sh, octopus) radiated in the Ceno- Kyushu University, Japan; California Academy zoic in all oceans. In the North Pacifi c, however, a turnover from belemnites to the modern of Science, USA) have also been done. Details types of cephalopods about 35 m.y. before the Cretaceous−Paleogene event documents a more of the localities, horizons, and the precise strati- complex evolutionary history of cephalopods than previously thought. Here we show that the graphic ages of Albian belemnites are shown in modern types of cephalopods originated and prospered throughout the Late Cretaceous in Table DR1 in the Data Repository.1 the North Pacifi c. The mid-Cretaceous cephalopod turnover was caused by cooling and the closure of the Bering Strait, which led to a subsequent faunal isolation of this area. -
Paleontological Contributions
THE UNIVERSITY OF KANSAS PALEONTOLOGICAL CONTRIBUTIONS May 15, 1970 Paper 47 SIGNIFICANCE OF SUTURES IN PHYLOGENY OF AMMONOIDEA JURGEN KULLMANN AND JOST WIEDMANN Universinit Tubingen, Germany ABSTRACT Because of their complex structure ammonoid sutures offer best possibilities for the recognition of homologies. Sutures comprise a set of individual elements, which may be changed during the course of ontogeny and phylogeny as a result of heterotopy, hetero- morphy, and heterochrony. By means of a morphogenetic symbol terminology, sutural formulas may be established which show the composition of adult sutures as well as their ontogenetic development. WEDEKIND ' S terminology system is preferred because it is the oldest and morphogenetically the most consequent, whereas RUZHENTSEV ' S system seems to be inadequate because of its usage of different symbols for homologous elements. WEDEKIND ' S system includes only five symbols: E (for external lobe), L (for lateral lobe), I (for internal lobe), A (for adventitious lobe), U (for umbilical lobe). Investigations on ontogenetic development show that all taxonomic groups of the entire superorder Ammonoidea can be compared one with another by means of their sutural development, expressed by their sutural formulas. Most of the higher and many of the lower taxa can be solely characterized and arranged in phylogenetic relationship by use of their sutural formulas. INTRODUCTION Today very few ammonoid workers doubt the (e.g., conch shape, sculpture, growth lines) rep- importance of sutures as indication of ammonoid resent less complicated structures; therefore, phylogeny. The considerable advances in our numerous homeomorphs restrict the usefulness of knowledge of ammonoid evolution during recent these features for phylogenetic investigations. -

Correlations of Hauterivian and Barremian (Early Cretaceous) Stage Boundaries to Polarity Chrons
EPSL ELSEVIER Earth and Planetary Science Letters 134 (1995) 125-140 Correlations of Hauterivian and Barremian (Early Cretaceous) stage boundaries to polarity chrons J.E.T. Channell a F. Cecca b, E. Erba c a Department of Geology, University of Florida, Gainesville, FL 32611, USA b Servizio Geologico Nazionale, Largo S. Susanna 13, O0187Rome, Italy c Dipartimento di Seienze della Terra, Universith degli Studi di Milano, 20133 Milan, Italy Received 27 March 1995; accepted 5 June 1995 Abstract Recent ammonite finds in Italian Maiolica limestones allow direct correlation of Hauterivian and Barremian ammonite zones (stage boundaries) to polarity chrons. At Laghetto and Alpetto (Lombardy, Italy), Lower Aptian ammonites occur just above polarity zone M0 and below the Selli Level, and Upper Barremian ammonites occur in polarity zone Mln. These correlations are consistent with the Barremian/Aptian boundary being close to older boundary of (polarity chron) CM0. The uppermost Hauterivian ammonite (Faraoni) guide level has been correlated to CM4 at Bosso (Umbria-Marche), confirming the recent correlation of the Hauterivian/Barremian boundary to CM4. At Monte Acuto (Umbria-Marche), ammonites spanning the Valanginian/Hauterivian boundary interval, and the last appearance of the nannofossil T. verenae, occur close to the CMll/CMlln boundary. The Valanginian/Hauterivian boundary has previously been placed between the first appearance of L. bollii and the last appearance of T. verenae, or between CM10 and CMll. The published Polaveno (Lombardy) magnetostratigraphy for the CM3-CMll interval has now been extended to CM16. This 260 m section, recording the CM3-CM16 interval, is the most complete single-section record of Cretaceous M-sequence polarity chrons. -
Synoptic Taxonomy of Major Fossil Groups
APPENDIX Synoptic Taxonomy of Major Fossil Groups Important fossil taxa are listed down to the lowest practical taxonomic level; in most cases, this will be the ordinal or subordinallevel. Abbreviated stratigraphic units in parentheses (e.g., UCamb-Ree) indicate maximum range known for the group; units followed by question marks are isolated occurrences followed generally by an interval with no known representatives. Taxa with ranges to "Ree" are extant. Data are extracted principally from Harland et al. (1967), Moore et al. (1956 et seq.), Sepkoski (1982), Romer (1966), Colbert (1980), Moy-Thomas and Miles (1971), Taylor (1981), and Brasier (1980). KINGDOM MONERA Class Ciliata (cont.)
