A review of helochelydrid shell material from late Albian to early Cenomanian greensands of Southern England, United Kingdom

open access: yesThe Anatomical Record, EarlyView., 2022
Abstract A number of helochelydrid turtle shell remains were recovered over the course of the 19th century from mid‐Cretaceous sediments throughout Southern England, including the poorly figured and described types of Trachydermochelys phlyctaenus from the Cambridge Greensand of Cambridgeshire, Plastremys lata from the Upper Greensand of the Isle of ...

First clear evidence of Anoplotherium (Mammalia, Artiodactyla) in the Iberian Peninsula: an update on the Iberian anoplotheriines

open access: yesThe Anatomical Record, EarlyView., 2023
Abstract Anoplotheriines (Mammalia, Artiodactyla) were enigmatic, medium‐ to large‐sized ungulates that lived in Western Europe from the late middle Eocene to the earliest Oligocene. The unusual dental and postcranial specializations of these Paleogene mammals have no equivalent in other Cenozoic or contemporaneous artiodactyls on Holarctic landmasses.

Lizards and amphisbaenians (Reptilia, Squamata) from the middle Eocene of Mazaterón (Soria, Spain)

open access: yesThe Anatomical Record, EarlyView., 2023
Abstract The assemblage of lizards and amphisbaenians (Reptilia, Squamata) from the middle Eocene locality of Mazaterón (Spain) is described. Considering the rather limited material available for the study, the assemblage shows a moderate diversity with eight taxa corresponding to five different families.

Source areas of the Eastern Ebro Valley loess (NE Iberian Peninsula): Heavy mineral composition as a provenance indicator

open access: yesEarth Surface Processes and Landforms, Volume 47, Issue 15, Page 3611-3628, December 2022., 2022
The loess provenance areas of the Ebro and Móra basins are mainly the fluvial terraces of the Middle and Lower Ebro River, respectively, according to the analyses of very heavy minerals and particle size. The wind transport distances are relatively short (<100 km).

Geoarchaeological characterisation of a Younger Dryas site in the Alpine uplands: Cornafessa rock shelter (Italy)

open access: yesGeoarchaeology, Volume 38, Issue 1, Page 35-56, January/February 2023., 2023
Abstract The effects of the Younger Dryas (YD) fluctuation on Late Pleistocene hunter‐gatherers' settlement and subsistence systems in the southern Alps are poorly known. This is primarily due to the scarcity of archaeological sites dating from the YD, in contrast with the extensive evidence available from the lateglacial interstadial and the early ...

Platinum Group Element Traces of CAMP Volcanism Associated With Low‐Latitude Environmental and Biological Disruptions

open access: yesGeophysical Monograph Series, Page 263-304., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Mid‐Cretaceous calcarenite in stone products from the Roman colony of Emona, Regio X (modern Ljubljana, Slovenia)

open access: yesArchaeometry, Volume 65, Issue 1, Page 17-35, February 2023., 2023
Abstract Over the course of studying stone products from the Roman colony of Emona (Regio X), stratigraphically undefined calcarenite that was used to make simple sepulchral and architectural stone products was detected. The calcarenite used is late Aptian to early Cenomanian in age.

A review of microbial‐environmental interactions recorded in Proterozoic carbonate‐hosted chert

open access: yesGeobiology, Volume 21, Issue 1, Page 3-27, January 2023., 2023
Abstract The record of life during the Proterozoic is preserved by several different lithologies, but two in particular are linked both spatially and temporally: chert and carbonate. These lithologies capture a snapshot of dominantly peritidal environments during the Proterozoic. Early diagenetic chert preserves some of the most exceptional Proterozoic

Permian parallelisms: Reanalysis of †Tshekardocoleidae sheds light on the earliest evolution of the Coleoptera

open access: yesSystematic Entomology, Volume 48, Issue 1, Page 69-96, January 2023., 2023
A reevaluation of †Tshecardocoleidae revealed that crucial character transformations took place in the Permian. Phylogenetic analyses show that Coleoptera excluding †Tshecardocoleidae are strongly supported as a clade (Mesocoleoptera). Taxon exclusion experiments demonstrate that †Tshecardocoleidae are crucial for understanding the early evolution of ...

A pan‐cheloniid turtle from the Middle Miocene of Portugal

open access: yesThe Anatomical Record, EarlyView.
Abstract 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.
