“…1a). Apart from its presentation in several symposia (Murelaga et al, 2007;Lapparent de Broin et al, 2017;Pérez-García et al, 2017c), two detailed papers were already consecrated to some of these turtles (Lapparent de Broin et al, 2014b;Pérez-García et al, 2017b). The turtle specimens were found between 1959 and 1970 by members of the Sección de Estudios científicos 1960, del Patronato de Estudios Ausonenses, currently GeoLab-Vic, associated with the Museu Geològic del Seminari de Barcelona for the fossil preservation.…”

“…The skull (lacking here) could be relevant for the determination of this genus, but the shell and other postcranial remains also provide important information, which is exclusive for this form. The skull characteristics have traditionally mainly been employed in previous papers (Lapparent de Broin et al, 2014b;Parham and Pyenson, 2010;Weems and Brown, 2017). However, the Osona postcranial elements of the new taxon share an exclusive characteristic combination with Eochelone brabantica, allowing the attribution of the new material to a new species of this genus.…”

Abstract. Eochelone voltregana n. sp. is a new marine cryptodiran cheloniid found at the Priabonian levels (latest Eocene) of the Vespella marls member of the Vic–Manlleu marls formation. It is the second cheloniid from Santa Cecília de Voltregà (Osona County, Spain), the first one being Osonachelus decorata from the same formation. Shell parameters indicate that the new species belongs to a branch of sea turtles including the Eocene Anglo–Franco–Belgian forms Argillochelys, Puppigerus and Eochelone (the shell of the latter was studied here for the first time) as well as Glarichelys from the Oligocene of Switzerland, all of them predating the worldwide living Miocene genera. The description of two other more littoral–continental Eocene species is given: Trionyx sp., from an older layer of the same formation; and the podocnemidid erymnochelyine, Cordichelys from a more basal layer of a middle Eocene (Lutetian) formation. The last one is identified as the only evidence of the Shweboemys subgroup in the European record, being distinct from the other known Osona County pleurodire Eocenochelus farresi, which is a member of the Erymnochelys group (same subfamily), from the younger Priabonian Sant Martí Xic layer. Thus, an update on the marine turtle fauna of the eastern Ebro Basin that variably opened in the east during Eocene times is provided. The turtles of Osona County belong to two suborders and five genera with three new species and extend the known distribution of their families (LSID urn:lsid:zoobank.org:act:48CE8676-7B82-4EF2-8165-27BEE90129F2).

“…The fossiliferous richness of the Eocene Plana de Vic is widely known. Several papers have been published to describe its fossil plant, invertebrate, and vertebrate records (e.g., Barnolas et al, ; de Lapparent de Broin, Murelaga, Farrés, & Altimiras, ; Farrés & Altimiras, ; Farrés & Staid‐Staadt, , , ; Farrés, Vicente, & Altimiras, ; Pérez‐García, de Broin, & Murelaga, ; Reguant et al, ; Serra‐Kiel et al, ). As far as fossil fishes are concerned, Farrés () described the sawfish Mesopristis osonensis , subsequently, Farrés and Altimiras () described the swordfish Cylindracanthus rectus (Agassiz, ), and finally, Farrés and Fierstine () documented the presence of the sawfish Propristis schweinfurthi Dames, .…”

Fish‐bearing deposits from the Upper Eocene Terminal Complex of the Plana de Vic (Catalonia, NE Spain): Sedimentary context and taphonomy

The Upper Eocene fish‐bearing deposits of the Terminal Complex of the Plana de Vic (Ebro Basin, Catalonia, NE Spain) and its fish assemblage are analysed in detail from a stratigraphic and sedimentological point of view. Moreover, the taphonomic features and taxonomy of the fishes are studied for the first time. Fishes belonging to the families Clupeidae, Synodontidae, and an indeterminate percomorph have been identified, including a new lizardfish taxon, Ausonasynodus almerai gen. et sp. nov. The fish specimens are preserved in finely laminated limestones, resulting from the development of microbial mats on the seafloor. The presence of these microbially induced biolaminations favoured the good preservation of the fossil material. The combination of the stratigraphic and sedimentological context of the studied deposits, together with the taphonomic and paleobiological information obtained from the fishes, suggest that they were likely deposited in a shallow marine setting, probably in restricted or protected areas, under arid climatic conditions.

Currently, there is no information on the fossil record of Pan‐Cheloniidae from the Neogene of the Iberian Peninsula. A well‐preserved partial skeleton attributable to this lineage of turtles, from the Middle Miocene of Portugal, is presented here. It preserves much of the anterior half of its carapace, in which the plates remain articulated, as well as several articulated dorsal vertebrae, and an isolated cervical and a caudal vertebrae. The analysis of this Serravallian find shows that it cannot be attributed to a hitherto described taxon. Thus, a new member of Pan‐Cheloniidae is defined, Lusochelys emilianoi gen. et sp. nov., improving the relatively limited knowledge about this lineage for the Middle Miocene global record. It represents the first generic and specific systematic attribution for a member of Pan‐Chelonioidea in the Neogene record of the Iberian Peninsula.
