Les Gonorynchiformes fossiles : distribution et diversité.
2007
8 pages; Longtemps placés dans les clupéiformes, les Gonorynchiformes ont rejoint les Ostariophysi au sein desquels ils représentent le groupe-frère des Otophysi. La monophylie du groupe est maintenant bien établie tant par les données morphologiques que moléculaires. De nos jours, quatre familles sont représentées par sept genres (dont cinq d'eau douce) et 35 espèces (dont 28 d'eau douce). Les Gonorynchiformes fossiles sont connus depuis le Crétacé basal (soit 145-140 millions d'années) jusqu'au Miocène basal (soit 23,5-20 millions d'années), et plusieurs taxons ont de grandes extensions temporelles. Ils sont représentés par environ 18 genres et 34 espèces. Avec moins de 50 localités fossi…

The Church of S. Maria Delle Palate in Tusa (Messina, Italy): Digitization and Diagnostics for a New Model of Enjoyment
2022
Cultural places represent the tangible part of the identity and historical heritage of a civilization as well as an extraordinary driving force for the economic development of a country. Within its huge asset, Italy counts a wide number of archaeological sites and monuments which, despite their cultural value, are totally cut off from the most important cultural routes. This paper aims to demonstrate how specific actions of digitization can contribute to valorize (restoring a cultural value) ‘marginal’ landmarks, promoting their knowledge and inclusion. The case study described is represented by the Church of “Santa Maria delle Palate”, located inside the well-known …

Histological characteristics of the vertebral intercentra of Metoposaurus diagnosticus (Temnospondyli) from the Upper Triassic of Krasiejów (Upper Si…
2012
ABSTRACTOsteohistological characteristics of the large temnospondyl amphibian Metoposaurus diagnosticus from the Upper Triassic of Poland (Krasiejów locality) were determined using vertebral intercentra thin-sections from different regions and growth stages. The intercentra showed a trabecular structure in both the endochondral and periosteal domains. Endochondral ossification developed first, and the primary bone occurs near the periphery with a higher degree of remodelling in the centre. Periosteal bone deposition begins later; first on the ventral side, continuing laterally and finally onto the dorsal side. Periosteal growth rate was initially very rapid, and then subsequently decreased …
Where are you from, stranger? The enigmatic biogeography of North African pond turtles (Emys orbicularis)
2014
Abstract The European pond turtle (Emys orbicularis) is a Nearctic element in the African fauna and thought to have invaded North Africa from the Iberian Peninsula. All North African populations are currently identified with the subspecies E. o. occidentalis. However, a nearly range-wide sampling in North Africa used for analyses of mitochondrial and microsatellite DNA provides evidence that only Moroccan populations belong to this taxon, while eastern Algerian and Tunisian pond turtles represent an undescribed distinct subspecies. These two taxa are most closely related to E. o. galloitalica with a native distribution along the Mediterranean coast of northern Spain through southern France …
Revision of the genusXyalaspisHartig, 1843 (Hymenoptera: Figitidae: Anacharitinae) in the Western Palaearctic
2015
ABSTRACT A revision of Xyalaspis Hartig, 1843 (Hymenoptera: Anacharitinae) in the Western Palaearctic region is given. Xyalaspis spinigera Reinhard, 1860 and Xyalaspis subulifera (Thomson, 1862) are synonymized with Xyalaspis laevigata Hartig, 1843 and Xyalaspis rugosa Hartig, 1843 respectively, and their distribution areas are extended. A new species Xyalaspis pseudolaevigata n. sp. is described from France. One species previously assigned to the genus Xyalaspis, X. laevis (Hedicke, 1914), is transferred to Aegilips Haliday, 1835. Diagnostic characters are illustrated and data about biology, distribution and morphological variability of the studied species are presented and discussed. A ke…

2014
The first comprehensive revision of the Western Palaearctic species of the genus Dinotrema Foerster, 1862 is provided. 174 species of this genus are redescribed and illustrated. Ten species are described as new, viz, D. acompressum sp. nov., D. cahitum sp. nov., D. collybiae sp. nov., D. digitatum sp. nov., D. glabrideum sp. nov., D. helote sp. nov., D. lepiotae sp. nov., D. norwegicum sp. nov., D. oxybellum sp. nov. and D. torpi sp. nov. The following new combinations are suggested: Dinotrema adventum (Fischer), comb. nov., D. aurelianum (Fischer), comb. nov., D. cetiusmonte (Fischer), comb. nov., D. converginerve (Fischer), comb. nov., D. intermissum (Fischer), comb. nov., D. leptocorne (…
Taxonomy and palaeobiogeography of the Cenozoic Euro-Mediterranean rissoid gastropod Galeodinopsis and its relationship with close genera
2014
The investigation of the Late Paleogene to Late Neogene species of rissoid gastropod Galeodinopsis in the Euro-Mediterranean area has supported the hypothesis that this genus is an intermediate form between two well-known rissoids, Alvinia and Manzonia. We recognized four species of Galeodinopsis: G. biangulata, G. germanica sp. nov., G. semperi (new name for Rissoa duboisii), and G. tiberiana. The oldest (very Late Eocene/Oligocene) representatives of Galeodinopsis, G. biangulata, and G. semperi, share similar shell shape and microsculpture with Alvinia. This suggests that Galeodinopsis originated from some Eocene species related to Alvinia. The new species represents the first occurrence …
