“…Occurrences of Early Jurassic elasmobranchs are almost exclusively known from Europe, where numerous chondrichthyan-bearing localities have been reported since the 19th century (e.g., Charlesworth 1839; de Beaumont 1960;Thies 1983;Delsate et al 1989;Delsate and Duffin, 1993;Duffin 1993Duffin , 1997Duffin , 2010Delsate and Godefroit 1995;Rees 1998Rees , 2000Delsate and Candoni 2001;Delsate et al 2002;Vincent et al 2013;Romano et al 2018). However, although the knowledge of Early Jurassic cartilaginous fishes has expanded substantially in recent decades, our understanding of their distributional patterns remains very heterogenous.…”

Here we describe a new, previously unrecognized elasmobranch microfossil assemblage consisting of isolated dental material from late Pliensbachian marginal marine, near-shore deposits of Grimmen in northeastern Germany. The faunal composition indicates close affinities to other European pre-Toarcian elasmobranch-bearing localities, as it is predominantly composed of Hybodontiformes (Hybodus reticulatus?, H. hauffianus?, Lissodus sp.), Synechodontiformes (Palidiplospinax enniskilleni, P. occultidens, Paraorthacodus sp., Sphenodus sp.), and Hexanchiformes (Notidanoides sp.), as well as teeth attributable of the enigmatic Early Jurassic galeomorph shark Agaleus dorsetensis. In addition, the here reported elasmobranch tooth assemblage includes the oldest undisputable fossil records of Orectolobiformes and Batomorphii, each being represented by a single complete tooth only. The orectolobiform specimen is reminiscent of hemiscyllids but left in open nomenclature due to its very generalized morphology preventing any taxonomic identification. The batomorph tooth, conversely, is characterized by a unique combination of morphological features, which allows the introduction of new genus and species, Antiquaobatis grimmenensis gen. et sp. nov. The fossil assemblage presented here contributes to our current knowledge of late Early Jurassic chondrichthyan diversity and distributional patterns, providing some support for the hypothesis that most modern neoselachian lineages were initially linked to marginal marine, near-shore environments, before moving into open marine, offshore habitats by the Toarcian.

“…), its record is relatively scarce in comparison to those from the Jurassic ( e.g. , Yabe, 1902 ; Priem, 1907 ; Peyer, 1946 ; Goto, Kuga & Hachiya, 1991 ; Goto, Uyeno & Yabumoto, 1996 ; Cuny, Suteethorn & Kamha, 2005 ; Cuny et al, 2007 ; Cuny et al, 2009 ; Cuny et al, 2014 ; Rees & Underwood, 2008 ; Vincent et al, 2013 ; Rigal & Cuny, 2016 ; Romano et al, 2018 ; Wills et al, 2019 ; Szabó & Főzy, 2020 ; Kumar et al, 2022 ; Sharma & Singh, 2021 ), and references therein). Most of the Strophodus records from the Cretaceous have been reported as indeterminate species from the Valanginian-Albian range of Europe, including England ( Batchelor & Ward, 1990 ), France ( Priem, 1912 ; Guinot, Cappetta & Adnet, 2014 ), and Switzerland ( Pictet & Campiche, 1858 ; Peyer, 1946 ), and these teeth look different to those of Strophodus rebecae sp.…”

A new hybodontiform shark (StrophodusAgassiz 1838) from the Lower Cretaceous (Valanginian-Hauterivian) of Colombia

The vertebrate marine faunas that inhabited northern South America during the Cretaceous are still poorly known. This study is a contribution to a growing wave of new studies on Lower Cretaceous vertebrates from Colombia. Here we report and describe a new species of a hybodontiform shark of the genus Strophodus, which we named Strophodus rebecae sp. nov., based on isolated teeth, that were collected in Valanginian-Hauterivian rocks of the Rosa Blanca Formation (Carrizal and El Sapo Members) near the town of Zapatoca, Santander Department, Andes of Colombia. In addition, we describe two other fragmented teeth assigned to Strophodus sp. from the Rosa Blanca Fm. The new species from Colombia represents the only Cretaceous record of Strophodus from Gondwana, offering new insights into the paleogeographic distribution of the genus, as well as increasing the knowledge about the scarce hybodontiform paleodiversity known from South America. The presence of Strophodus in the Rosa Blanca Formation suggests that these durophagous (shell-crushing) fishes played an important role as predators of the abundant and diverse invertebrate fauna present in these ancient tropical coastal ecosystems of Gondwana.

The aluminum and iron mines of the Comino Valley-Sora area (Central Apennines, Italy): sites of the geological memory

The Mesozoic bauxitic-limonitic deposits of the Comino Valley-Sora area have been exploited since proto-historic times, but this area became crucial for the "iron rush" in the Bourbon era. The Kingdom of Naples decided to finance scientific researches in the area between Pescosolido and Picinisco (southeastern Lazio), in order to strengthen military defenses and to combat invasive or rebellious pressures. This led to the realization, in the period between 1770 and 1860, of the Royal Mines of Canneto, San Donato Val di Comino and Campoli Appennino, and of the Royal Forges of Canneto and Rosanisco. Fundamental was the supervision of technicians, including the engineer and geologist Gaetano Tenore. Following the Bourbon crisis of 1860, the industrial activity of the area was abandoned with, in many cases, its definitive loss of evidence (e.g. many of the mines of Campoli and San Donato Val di Comino, as well as the Canneto forge). The geological relevance of the mineralogical and stratigraphic studies performed in this area (with their socio-cultural and economic implication), coupled with the fact that most of this geological heritage is disappearing, allowed to identify several "sites of geological memory" in this area.
