Summary: This article tells the story of Abel Vautier and Pierre-Gilles Moriere collecting Jurassic marine reptile specimens in Normandy, France, which were ultimately destroyed in the bombing of Caen in 1944. These specimens include some iconic holotypes, some of which have been rediscovered through their plaster casts.

Summary: Dinosaur remains found at the Vaches Noires cliffs in Normandy, predominantly belonging to theropods, have been primarily discovered by amateur palaeontologists and mostly held in private collections. This study brings together private and public collections to gain a comprehensive understanding of theropod remains from this locality. The overabundance of theropod remains in this area, compared to similar deposits, is both intriguing and puzzling. At least three taxa have been tentatively identified from these remains.

Summary: This article discusses the collection of Jacques-Ludomir Combes, a pharmacist who had the most significant collection of fossils and prehistoric objects in the Lot-et-Garonne department during his time. He sold his collection to the Museum of Agen in 1880, where it was exhibited. The collection includes various vertebrate remains from the Upper Kimmeridgian period, which were studied by Henri-Emile Sauvage in the early 1900s and rediscovered recently.

Summary: This study focuses on building a regional scale 3D geological model of the Pays d'Auge Plateau in Normandy, France, and studying the Vaches Noires Cliffs. It characterizes the geometry of geological layers, estimates the volume of each unit, and discusses the role of clayey soils on the erosive process of the cliffs. It also explores potential applications of the 3D geological model for further research on coastal retreat in Normandy.

Summary: This study presents the fossil remains of metriorhynchids from the Jurassic period in Normandy. By analyzing the discovered specimen, the author questions the taxonomic value of several criteria used to classify different species and discusses the limitations of current classification methods.

Summary: Marine reptile faunas from the Lower Jurassic Series in Eastern Siberia show a cosmopolitan nature, with the presence of taxa previously known from Europe. These diverse faunas, including plesiosaurians and ichthyosaurians, suggest a possibility of breeding in polar seas. The lack of thalattosuchian remains and the potential seasonal migrations support the high metabolism of these groups in polar environments.

Summary: This study focuses on the evolution of the coastal badlands in Normandy, France and aims to understand their functioning and assess the potential of Terrestrial Laser Scanner (TLS) tool in quantifying the volumes moved and rates of change. The study monitored three gullies with different dynamics and identified seasonal patterns of hydro-gravitational dynamics. The results show erosion in the upper slopes, alternating erosion and deposition in the middle and lower parts of the gullies, and progradation at the foot of the cliff. The TLS tool is relevant for monitoring the evolutionary processes of cliffs with complex topography and rapid morphological changes.

Summary: Metriorhynchidae is an extinct clade of crocodylomorphs adapted to a pelagic lifestyle, with the type genus Metriorhynchus being well-known. However, the traditional concept of Metriorhynchus being non-monophyletic led to the establishment of a new genus Thalattosuchus for Me. superciliosus to address this issue.

Summary: A new marine crocodylomorph fossil species, Torvoneustes jurensis sp. nov., was discovered in Porrentruy, Switzerland. The fossil includes relatively complete remains of the skull and skeleton. The description of this new species provides new insights into the evolutionary trends of the genus Torvoneustes.

Summary: Ischyrodon meriani is a little-known pliosaurid taxon based on a large tooth crown. Despite being known for almost two centuries, the specimen remains poorly researched. The study suggests that it shares similarities with Liopleurodon ferox, but due to the limited knowledge of dental variability in L. ferox and the fragmentary nature of the type specimens, it is currently best treated as a nomen dubium.

Summary: Owadow-Brzezinki is an important Upper Jurassic site in Central Poland, known for its diverse fossil fauna including large marine reptiles. In this report, four isolated teeth with distinct features of plesiosaurians were discovered, confirming the presence of Plesiosauroidea in the Owadow-Brzezinki Lagerstatte. This finding highlights the significance of the site as a mix zone between different faunas and expands the range of fossil taxa found in the area.

Summary: A turnover in marine reptile communities occurred during the Early-Middle Jurassic transition, leading to the extinction of some early clades and the rise of new dominant groups. Fossil records from Luxembourg and Belgium provide insight into the evolution of marine reptile assemblages during this period.

Summary: Two new genera and species of Dermaptera are described from the Middle Jurassic Jiulongshan Formation of Daohugou, Inner Mongolia, China. Applanatiforceps angustus belongs to the archidermapteran family Protodiplatyidae, and Ekpagloderma gracilentum belongs to the eodermapteran family Semenoviolidae. The discovery of these two new species enriches the fossil record of Dermaptera and highlights the diversity within this group.

Summary: The discovery of a new plesiosaur species in Portugal reveals a unique combination of features, placing it as the most complete and oldest plesiosaur in the Iberian Peninsula. This specimen provides valuable insights into the early marine reptile populations in the region prior to the formation of the Atlantic Ocean.

Summary: Several well-preserved specimens of an early Jurassic plesiosaur called "Plesiosaurus bavaricus" have been found in the Posidonia Shale in Bavaria, Germany. Although incomplete, these specimens are believed to belong to a distinct species or group of species that are different from other plesiosaurs known from the Posidonia Shale. Additionally, another cervical vertebra with striking similarities to the type cervicals of 'P'. bavaricus has been discovered.
