They can be printed, colored, cutout and assembled. Printing on firm paper is helpful (next page only).). The paper model collection was created by Tau Rho Alpha, Scott W. Starratt, and James W. Hendley, USGS, Menlo Park CA. Nautiloid - two pieces The Nautiloid model consists of the shell and head. Color it any way you like and then follow these directions to assemble it. Your finished Nautiloid will look like the model below. Nautiloids are a subclass of marine mollusks that have been around for about 500 million years. There were more than 2500 species of Nautiloids. This one is straight-bodied; there are also coiled Nautiloids, like the Nautilus which is still in the oceans today.

  • First Record of Non-Mineralized Cephalopod Jaws and Arm Hooks
    Klug et al. Swiss J Palaeontol (2020) 139:9 https://doi.org/10.1186/s13358-020-00210-y Swiss Journal of Palaeontology RESEARCH ARTICLE Open Access First record of non-mineralized cephalopod jaws and arm hooks from the latest Cretaceous of Eurytania, Greece Christian Klug1* , Donald Davesne2,3, Dirk Fuchs4 and Thodoris Argyriou5 Abstract Due to the lower fossilization potential of chitin, non-mineralized cephalopod jaws and arm hooks are much more rarely preserved as fossils than the calcitic lower jaws of ammonites or the calcitized jaw apparatuses of nautilids. Here, we report such non-mineralized fossil jaws and arm hooks from pelagic marly limestones of continental Greece. Two of the specimens lie on the same slab and are assigned to the Ammonitina; they represent upper jaws of the aptychus type, which is corroborated by fnds of aptychi. Additionally, one intermediate type and one anaptychus type are documented here. The morphology of all ammonite jaws suggest a desmoceratoid afnity. The other jaws are identifed as coleoid jaws. They share the overall U-shape and proportions of the outer and inner lamellae with Jurassic lower jaws of Trachyteuthis (Teudopseina). We also document the frst belemnoid arm hooks from the Tethyan Maastrichtian. The fossils described here document the presence of a typical Mesozoic cephalopod assemblage until the end of the Cretaceous in the eastern Tethys. Keywords: Cephalopoda, Ammonoidea, Desmoceratoidea, Coleoidea, Maastrichtian, Taphonomy Introduction as jaws, arm hooks, and radulae are occasionally found Fossil cephalopods are mainly known from preserved (Matern 1931; Mapes 1987; Fuchs 2006a; Landman et al. mineralized parts such as aragonitic phragmocones 2010; Kruta et al.

  • Colour Patterns on Silurian Orthocerid and Pseudorthocerid Conchs from Gotland – Palaeoecological Implications

The longitudinal colour pattern – an adaptively controlled feature functioning in cephalopods as camouflage – is described in two straight-shelled cephalopods from the Silurian of Gotland. A shell of the orthocerid Dawsonoceras annulatum (Sowerby) exhibits relatively broad longitudinal colour bands around the entire shell circumference, which in combination with transverse annuli and undulated growth ridges form a visually reticulate ornament. Such a combination is not known in other Silurian straight-shelled cephalopods. Dawsonoceras annulatum is the only known Palaeozoic cephalopod retaining an almost identical colour pattern in populations inhabiting different palaeo-continents. The shell of the pseudorthocerid Lyecoceras? columnare (Marklin) has densely packed narrow longitudinal colour bands on the entire smooth shell. In this feature the species is very similar to other Silurian and Ordovician pseudorthocerids. However, in Ordovician pseudorthocerids colour bands are restricted dorsally. The type of colouration described herein differs from that of Devonian and younger pseudorthocerids where the shell bears zig-zag bands. Longitudinal colouration around the entire shell circumference supports vertical or subvertical life orientation in both described species. Key words: Silurian, Orthocerida, Pseudorthocerida, colour pattern, palaeoecology. INTRODUCTION poorly known in comparison with oncocerids and discosorids (Nautiloidea).

  • Adaptive Evolution in Paleozoic Coiled Cephalopods
    Paleobiology, 31(2), 2005, pp. 253±268 Adaptive evolution in Paleozoic coiled cephalopods BjoÈrn KroÈger Abstract.ÐCoiled cephalopods constitute a major part of the Paleozoic nekton. They emerged in the Early Ordovician but nearly vanished in the Silurian. The Emsian appearance of ammonoids started a story of evolutionary success of coiled cephalopods, which lasted until the end-Permian extinction event. This story is investigated by using a taxonomic database of 1346 species of 253 genera of coiled nautiloids and 1114 genera of ammonoids. The per capita sampling diversities, the Van Valen metrics of origination and extinction, and the probabilities of origination and ex- tinction were calculated at stage intervals. The outcome of these estimations largely re¯ects the known biotic events of the Paleozoic. The polyphyletic, iterative appearance of coiled cephalopods within this time frame is interpreted to be a process of adaptation to shell-crushing predatory pres- sure. The evolution of the diversity of coiled nautiloids and ammonoids is strongly correlated with- in the time intervals. Once established, assemblages of coiled cephalopods are related to changes in sea level. The general trends of decreasing mean (or background) origination and extinction rates during the Paleozoic are interpreted to re¯ect a successive stabilization of the coiled cephalopod assemblages. Different reproduction strategies in ammonoids and nautiloids apparently resulted in different modes of competition and morphological trends. Signi®cant morphological trends to- ward a stronger ornamentation and a centrally positioned siphuncle characterize the evolution of Paleozoic nautiloids. BjoÈrn KroÈger.

  • High-Level Classification of the Nautiloid Cephalopods: a Proposal for the Revision of the Treatise Part K

King • David H. Evans Received: 4 November 2018 / Accepted: 13 February 2019 / Published online: 14 March 2019 Ó Akademie der Naturwissenschaften Schweiz (SCNAT) 2019 Abstract High-level classification of the nautiloid cephalopods has been largely neglected since the publication of the Russian and American treatises in the early 1960s. Although there is broad general agreement amongst specialists regarding the status of nautiloid orders, there is no real consensus or consistent approach regarding higher ranks and an array of superorders utilising various morphological features has been proposed. With work now commencing on the revision of the Treatise Part K, there is an urgent need for a methodical and standardised approach to the high-level classification of the nautiloids. The scheme proposed here utilizes the form of muscle attachment scars as a diagnostic feature at subclass level; other features (including siphuncular structures and cameral deposits) are employed at ordinal level. We recognise five sub- classes of nautiloid cephalopods (Plectronoceratia, Multiceratia, Tarphyceratia nov., Orthoceratia, Nautilia) and 18 orders including the Order Rioceratida nov. which contains the new family Bactroceratidae. This scheme has the advantage of relative simplicity (it avoids the use of superorders) and presents a balanced approach which reflects the considerable morphological diversity and phylogenetic longevity of the nautiloids in comparison with the ammonoid and coleoid cephalopods.

  • Utilizing Hydrostatics to Describe the Paleoecology of Orthoceras, an Extinct Fossil Nautiloid
    Utilizing Hydrostatics to Describe the Paleoecology of Orthoceras, an Extinct Fossil Nautiloid Vaserman, Ellie (School: Staten Island Technical High School) Orthoceras is an extinct genus of Nautiloids, characterized by a straight, conical shell. These inhabited seas 450 million years ago, and are related to cephalopods, which are keystone species in decline. These elusive species are hard to study as a result of the depths they inhabit, and paleoecology can thus be an alternative to protect them from extinction. This project intends to determine the extent to which mathematical models, fluid dynamics, and hydrostatics can be used to determine the paleoecology of Orthoceras . It is hypothesized that Orthoceras had a horizontal living orientation, and used water in a system of jet propulsion to move, as a result of similarities between Orthoceras and extant Nautilus . To test the hypothesis, Pyplot was used to create contour plots to generate a hypothetical Orthoceras . A vertically-sliced shell of Nautilus pompilius was measured. Curves were generated for septal thickness, positioning, and chamber size, relative to shell diameter; these were used to plot septa on the hypothetical shell, and then find the sizes of the body, shell, and phragmocone. Center of mass and center of buoyancy equations were created for Orthoceras , and were then used to calculate the stability index. Volumes of water were then added to the apex of the shell, which moved up the center of mass, eventually creating a stability index of 0 when the water volume was 470 cm^3. The increased stability of the shell with water supported the conclusion that Orthocones used siphuncular water in a system of jet propulsion to move..

Harper The tristichopterid fishes: Almost, but not quite, tetrapods Per Erik Ahlberg Department of Palaeontology, The Natural History Museum, Cromwell Road, London SW7 5BD, UK <[email protected]> The clade Tristichopteridae occupies a relatively high position within the tetrapod stem group; it is the most advanced “osteolepiform” group, and forms the sister taxon to Panderichthys + tetrapods. The best known tristichopterid is the primitive early Frasnian genus Eusthenopteron, but the clade persisted to the end of the Devonian. The phase of rapid morphological change traditionally identified as the “fish-tetrapod transition” begins with the late Givetian Panderichthys and continues through to Famennian stem-group tetrapods such as Acanthostega and Ichthyostega. By contrast, the less crownward “osteolepiform fish” part of the stem group shows limited morphological change and no obvious overall trend towards terrestriality. However, within the Tristichopteridae there is independent acquisition of a Panderichthys-like body morphology. Recently, the advanced late Frasnian tristichopterid Mandageria has been found to possess a true neck joint, previously thought to be a unique tetrapod character. The extent, nature, TALKS and likely ecological significance of the convergence between tristichopterids and tetrapods will be discussed in the light of these findings. Phylogenetic analysis of the tetrapod stem group has shown that the lower, “fish” part consists of (in ascending sequence) the clade Rhizodontida, a paraphyletic array of osteolepiforms, the clade Tristichopteridae, and Panderichthys. In morphological terms, the “fish-tetrapod transition” begins at the level of Panderichthys.
