Stable isotope study of a new chondrichthyan fauna (Kimmeridgian, Porrentruy, Swiss Jura): an unusual freshwater-influenced isotopic composition for the hybodont shark Asteracanthus

Leuzinger, Léa Sylvia; Kocsis, Laszlo; Billon Bruyat, Jean Paul; Spezzaferri, Silvia; Vennemann, Torsten (Copernicus Publications, 2015-08)

Chondrichthyan teeth (sharks, rays and chimaeras) are mineralised in isotopic equilibriumwith the surrounding water, and parameters such as water temperature andsalinity can be inferred from the oxygen isotopic composition ...

First report of hybodont shark from the toarcian rosso ammonitico formation of umbria-marche apennine (polino area, terni, central Italy)

Romano, Marco; Citton, Paolo; Cipriani, Angelo; Fabbi, Simone (Societa Geologica Italiana, 2018-02)

In this contribution we present the first material referable to hybodont shark from the Rosso Ammonitico Formation (Umbria-Marche-Sabina Palaeogeographic Domain). Two teeth were recovered isolated within Toarcian red ...

A new chondrichthyan fauna from the Late Jurassic of the Swiss Jura (Kimmeridgian) dominated by hybodonts, chimaeroids and guitarfishes

Leuzinger, Léa Sylvia; Cuny, Gilles; Popov, Evgeny; Billon Bruyat, Jean Paul (Wiley-Blackwell Publishing Ltd, 2017-08)

The fossil record of chondrichthyans (sharks, rays and chimaeroids) principally consists of isolated teeth, spines and dermal denticles, their cartilaginous skeleton being rarely preserved. Several Late Jurassic chondrichthyan ...

Hybodont dentition from the Upper Jurassic of Monte Nerone Pelagic Carbonate Platform (Umbria-Marche Apennine, Italy) and its ecological implications

Citton, Paolo; Fabbi, Simone; Cipriani, Angelo; Jansen, Maren; Romano, Marco (John Wiley & Sons Ltd, 2019-01)

Here we describe a number of articulated teeth of a hybodont shark from Upper Jurassic deposits of the Monte Nerone Pelagic Carbonate Platform, in the Umbria-Marche-Sabina Palaeogeographic Domain (Northern Apennines, Central ...

First remains of neoginglymodian actinopterygians from the Jurassic of Monte Nerone area (Umbria-Marche Apennine, Italy)

Romano, Marco; Cipriani, Angelo; Fabbi, Simone; Citton, Paolo (Società Geologica Italiana, 2019-02)

Since the early nineteenth century, the structural high of Mt. Nerone in the Umbria-Marche-Sabina Domain (UMS - Central/ Northern Apennines, Italy) attracted scholars from all over Europe due to the wealth of fossil fauna ...
