Colour Patterns in Early Devonian Cephalopods from the Barrandian Area: Taphonomy and Taxonomy
Colour patterns in Early Devonian cephalopods from the Barrandian Area: Taphonomy and taxonomy VOJTĚCH TUREK Turek, V. 2009. Colour patterns in Early Devonian cephalopods from the Barrandian Area: Taphonomy and taxonomy. Acta Palaeontologica Polonica 54 (3): 491–502. DOI: 10.4202/app.2007.0064. Five cephalopod specimens from the Lower Devonian of Bohemia (Czech Republic) preserve colour patterns. They in− clude two taxonomically undeterminable orthoceratoids and three oncocerid nautiloids assigned to the genus Ptenoceras. The two fragments of orthocone cephalopods from the lowest Devonian strata (Lochkovian, Monograptus uniformis Zone) display colour patterns unusual in orthoceratoids. They have irregular undulating and zigzag strips that are pre− served on counterparts of adapertural regions of specimens flattened in shale, despite their original aragonitic shell having been completely dissolved. These are probably the result of the proteinous pigment inside the shell wall, being substituted during diagenesis by secondary minerals leaving only an altered trace of the original shell. Orthoceratoids from sediments unsuitable for preservation of this feature discussed here thus demonstrate an exceptional case of preservation of colour patterns, not only within Devonian cephalopods but also within other Devonian molluscs. Three specimens of Ptenoceras that preserve colour patterns come from younger Lower Devonian strata. Oblique spiral adaperturally bifurcating bands are preserved in P. alatum from the Pragian and zigzags in P. nudum from the Dalejan. Juvenile specimen of Ptenoceras? sp. from the Pragian exhibits highly undulating transversal bands—a pattern resembling colour markings in some Silu− rian oncocerids. Dark grey wavy lines observed on the superficially abraded adapical part of a phragmocone of nautiloid Pseudorutoceras bolli and interpreted formerly to be colour markings are here reinterpreted as secondary pigmented growth lines. -

The following list has been prepared by Dr. Theodore Gill, at the request of the Smithsonian Institution, for the purpose of facilitating the arrangement and classification of the Mollusks and Shells of the National Museum ; and as frequent applica- tions for such a list have been received by the Institution, it has been thought advisable to publish it for more extended use.

The want of a complete and consistent list of the principal subdivisions of the mollusks having been experienced for some time, and such a list being at length imperatively needed for the arrangement of the collections of the Smithsonian Institution, the present arrangement has been compiled for that purpose. It must be considered simply as a provisional list, embracing the results of the most recent and approved researches into the systematic relations and anatomy of those animals, but from which innova- tions and peculiar views, affecting materially the classification, have been excluded. -
Colour Patterns on Silurian Orthocerid and Pseudorthocerid Conchs from Gotland – Palaeoecological Implications
Estonian Journal of Earth Sciences, 2015, 64, 1, 74–79 doi: 10.3176/earth.2015.13 Colour patterns on Silurian orthocerid and pseudorthocerid conchs from Gotland – palaeoecological implications Štěpán Mandaa and Vojtěch Turekb a Czech Geological Survey, Klárov 3, 11821 Praha 1, Czech Republic; [email protected] b National Museum, Department of Palaeontology, Václavské náměstí 68, 115 79 Praha 1, Czech Republic; [email protected] Received 30 June 2014, accepted 17 October 2014 Abstract. 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). -

High-Level Classification of the Nautiloid Cephalopods: a Proposal for the Revision of the Treatise Part K
Swiss Journal of Palaeontology (2019) 138:65–85 https://doi.org/10.1007/s13358-019-00186-4 (0123456789().,-volV)(0123456789().,- volV) REGULAR RESEARCH ARTICLE High-level classification of the nautiloid cephalopods: a proposal for the revision of the Treatise Part K 1 2 Andy H. 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. -
Annual Meeting 1996

Thomas Print out a form and register for the meeting now! Trilobites, phylogenetic context, and the Palaeozoic Evolutionary Fauna JONATHAN M. ADRAIN Department of Palaeontology, Natural History Museum, Cromwell Road, London SW7 5BD Trilobites represent the dominant component of Sepkoski's (1981, 1984) Cambrian Evolutionary Fauna. As a clade, they reached peak taxonomic diversity from the Late Cambrian to the Middle Ordovician. Their subsequent history reflects crisis at the end-Ordovician mass extinction followed by continuous reduction until their end-Permian disappearance. Conventional interpretation of this pattern recognizes a transition near the base of the Middle Ordovician (Whiterockian), involving a shift in marine communities from earlier trilobite-dominated assemblages to articulate brachiopod- rich faunas of the rapidly radiating Palaeozoic Fauna. The actual mechanisms remain controversial (e. g. passive dilution v. active displacement), but there is little question that trilobites as a whole became relatively minor components of many mid-Palaeozoic communities. The overall pattern of Ordovician-Silurian trilobite decline is, however, misleading. While the clade as a whole was in quantitative taxonomic decline, no single natural subgroup of trilobites has a diversity history corresponding to this cumulative pattern. In addition, the best available estimates of trilobite alpha diversity (Adrain and Westrop, 1996) indicate stasis in within-community trilobite species richness from Upper Cambrian to Upper Silurian. This disparity is accounted for in part by a new phylogeny-based compilation of trilobite generic abundance. When post-Ordovician trilobites are resolved as suprageneric monophyla, these clades may be traced to encompass their Ordovician origins. -
