Ekrt, B. (2014): Late Cretaceous nautilid juveniles of Cymatoceras reussi and Eutrephoceras aff. sublaevigatum – scarce fossils under risk of pyrite degradation. – Acta Mus. Nat. Pragae, Ser. B, Hist. Nat., 70(3-4): 143–152, Praha. ISSN 1804-6479. Abstract. The syntype collection of “Nautilus reussi” has been subject to a detailed revision resulting in confirmation of at least provisional validity of the species represented by a single juvenile specimen. This species, restricted now to the Late Coniacian, is inserted into the genus Cymatoceras Hyatt, 1884. The rest of the collection differs from the original description and is left separately as Eutrephoceras aff. sublaevi- gatum, being considered juveniles of the species. The lithology, geographic and stratigraphic position of the type locality of Cymatoceras reussi (FRITSCH IN FRITSCH ET SCHLÖNBACH, 1872) as well as the other sites are discussed here. The valuable material is endangered due to pyrite degradation as relics of this unstable sulphide are still at present hidden in the secondary limonitic material. The degradation products cause volumetric expansion resulting in formation of crevices and loss of integrity. -

Constructional Morphology of Cerithiform Gastropods
Paleontological Research, vol. 10, no. 3, pp. 233–259, September 30, 2006 6 by the Palaeontological Society of Japan Constructional morphology of cerithiform gastropods JENNY SA¨ LGEBACK1 AND ENRICO SAVAZZI2 1Department of Earth Sciences, Uppsala University, Norbyva¨gen 22, 75236 Uppsala, Sweden 2Department of Palaeozoology, Swedish Museum of Natural History, Box 50007, 10405 Stockholm, Sweden. 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. -
