The evolution of a key character, or how to evolve a slipper lobster [PDF]
, 2016 International audienceA new fossil lobster from the Cretaceous of Lebanon, Charbelicaris maronites gen. et sp. nov., is presented here, while the former species ‘Cancrinos’ libanensis is re-described as Paracancrinos libanensis comb. nov. P.

Newinsights in the ontogeny and taphonomy of the Devonian acanthodian Triazeugacanthus affinis from the Miguasha Fossil-Lagerstatte, Eastern Canada [PDF]
, 2015 Progressive biomineralization of a skeleton occurs during ontogeny in most animals. In fishes, larvae are poorly mineralized, whereas juveniles and adults display a progressively more biomineralized skeleton.

Papers in Palaeontology, Volume 11, Issue 6, November/December 2025.Abstract The Villaggio del Pescatore (VdP) fossil Lagerstätte represents the most significant Upper Cretaceous (lower–middle Campanian) palaeontological locality in Italy and the Mediterranean region. We present the first systematic revision of the VdP fossil assemblage with a focus on its previously undescribed arthropod fauna, providing new insights ...

Arthroaspis n. gen., a common element of the Sirius Passet Lagerstätte (Cambrian, North Greenland), sheds light on trilobite ancestry [PDF]
, 2013 Background: Exceptionally preserved Palaeozoic faunas have yielded a plethora of trilobite-like arthropods, often referred to as lamellipedians. Among these, Artiopoda is supposed to contain taxa united by a distinctive appendage structure. This includes

Historical Biogeography of Spiny Lobsters in the Genus Panulirus (Achelata: Palinuridae)
Journal of Biogeography, Volume 52, Issue 11, November 2025.ABSTRACT Aim Panulirus is the spiny lobster genus with the most living species, containing 22 recognised species split into two lineages distinguished by habitat preference. Diversification has been proposed to occur due to geographic events affecting the distribution of adults and the dispersal potential of long‐lived larvae by oceanic currents ...

Microstructural and geochemical evidence offers a solution to the cephalopod cameral deposits riddle
Palaeontology, Volume 68, Issue 6, November/December 2025.Abstract Orthoceratoid cephalopods are common in the Palaeozoic rock record but went extinct in the Late Triassic. Many orthoceratoids contain cameral deposits, which are enigmatic calcareous structures within their chambered shell that presumably balanced their straight conchs in a horizontal position. Since the mid‐19th century, palaeontologists have

The Paleosalinity Context for the Ecological Pattern of the Chengjiang Biota
Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.Abstract The Chengjiang biota provides critical insights into metazoan diversification during the Cambrian Explosion, preserved at multiple localities with varying fossil abundances across the Chengjiang Bay. This work reports new B/Ga and B/K data from three drill cores near fossil localities, to evaluate salinity influences on ecological distribution

Sea surface temperature contributes to marine crocodylomorph evolution [PDF]
, 2014 During the Mesozoic and Cenozoic, four distinct crocodylomorph lineages colonized the marine environment. They were conspicuously absent from high latitudes, which in the Mesozoic were occupied by warm-blooded ichthyosaurs and plesiosaurs.

Permian scorpions from the Petrified Forest of Chemnitz, Germany [PDF]
, 2016 Background: Paleozoic scorpions (Arachnida: Scorpiones) have been widely documented from the Carboniferous Period; which hosts a remarkable assemblage of more than sixty species including both putative stem- and crown-group fossils.

The first pterosaur from the Bauru Group: an azhdarchid from the Upper Cretaceous of Brazil
Papers in Palaeontology, Volume 11, Issue 5, September/October 2025.Abstract The vertebrate fossil record of the Bauru Group (Upper Cretaceous, southeastern Brazil) is remarkably rich, with a predominance of titanosaurs and crocodyliforms, alongside theropods, turtles, squamates, fishes and even small mammals. In contrast, pterosaur remains from the Bauru Group have remained elusive until now.
