Summary: Recent findings in the Zuhanya Limestone Formation in the Mecsek Mountains of south Hungary provide evidence of nautiloid and ammonoid fossils from the Middle Triassic. These findings support previous assumptions about the paleogeographical location of the Mecsek region during this time period.

Summary: Measuring locomotion tactics of ancient sea animals can provide insights into the evolution and ecology of cephalopods with straight shells. The study found that orthocones require very low input thrust for high output in movement and velocity, suggesting they may have been efficient in vertical migration with low metabolic cost.

Summary: A multifunctional implant surface, based on the controlled deposition of cellulose nanocrystals (CNC) and biological activity derived from platelet lysate (PL) biomolecules, is proposed to promote soft tissue integration to metallic implants while preventing bacterial invasion, tissue inflammation, and failure of biomedical metallic implants. The anisotropic radial nanopatterns on polished titanium surfaces guide fibroblasts growth and alignment, while PL-derived biomolecules polarize macrophages toward the M2-like anti-inflammatory phenotype.

Summary: The research suggests that septal crowding alone is not enough to identify adulthood in ammonoids; intermediate septal crowding is common and occurs in various growth stages. Changes in septal distances during ontogeny are mainly a passive reaction likely caused by fluctuating environmental conditions.

Summary: This study estimates the number and biomass of ammonoids preserved in the eastern Anti-Atlas region, specifically in the Tafilalt and Maider basins. The analysis of samples suggests a high abundance of ammonoids in the Famennian strata, with estimated annual accumulation and total palaeo-biomass values. The ecological role and reproductive rates of these small and abundant ammonoids from the early and middle Famennian periods are also discussed.

Summary: The aim of this study was to assess the safety and efficacy of transarterial embolization (TAE) for spontaneous soft-tissue hematoma (SSTH) and to identify predictive factors for early mortality. The results showed that the retroperitoneal location and volume of hematoma were associated with early mortality after TAE for SSTH.

Summary: Heterocorals, an enigmatic group of Palaeozoic corals, display unique colony development not found in other anthozoans, leading to the proposal of including them in the subclass Octocorallia. This suggestion, based on skeleton structure and branching patterns, requires further research on other heterocoral taxa to be validated. Additionally, changes to the morphological terminology for Heterocorallia are proposed.

Summary: Ammonoid cephalopods are scarce in the sedimentary rocks of Belgium, but recent discoveries have added to our knowledge of Lower and Middle Devonian ammonoid occurrences. This study describes the first record of the Subanarcestes genus from Belgium, based on a specimen collected over a century ago. The use of micro-CT imaging played a crucial role in the taxonomic identification of the specimen.

Summary: In this paper, a new macroscopic approach is proposed to simulate stress-driven volumetric growth in soft tissues. By introducing a growth potential and using methods from visco-plasticity, the evolution of the growth-related Cauchy-Green tensor is defined, allowing for both isotropic and anisotropic growth changes and flexible adaptation to different boundary and loading conditions.

Summary: Despite the excellent fossil record of cephalopods, their early evolution remains poorly understood. In this study, researchers conducted a comprehensive phylogenetic analysis of Cambrian and Ordovician cephalopods and resolved existing controversies. The results revealed three major monophyletic groups, and clarified the evolutionary pathways. The study also provided insights into the application of Bayesian phylogenetic inference on morphological datasets, suggesting the use of quartet similarity metrics and posterior pruned maximum clade credibility trees for assessing support for phylogenetic relationships among relevant taxa.

Summary: This study reveals that fossil plants from the Early Devonian had different modes of secondary growth, indicating that secondary growth is a modular structure composed of various regulatory mechanisms. The diverse structural features of the fossil plants suggest that the origins of secondary growth and its modular components pre-date the Early Devonian.

It is the most diverse Carboniferous nautiloid assemblage known from North Africa, but less diverse than the assemblages from Belgium and Ireland.

Summary: The geological section at Baghuk Mountain in Central Iran provides excellent exposures of fossiliferous marine sedimentary successions from the Late Permian to Early Triassic. Detailed analysis of microfacies changes across the Permian-Triassic boundary reveals that carbonate production and biogenic activity ceased simultaneously during the main mass extinction event towards the end of the Permian period.

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: This study explores the relationship between the phragmocones of coleoid cephalopods and depth, finding that deep water-inhabiting sepiids have distinct characteristics in their phragmocones, such as more septa per length, a smaller area covered by the last chamber, smaller size, and strengthening central rib(s) on their dorsal shields. The subgenera defined by Khromov are not monophyletic clades but morphological groupings associated with depth. Additionally, the study analyzes Australian sepiid assemblages and demonstrates depth-related patterns similar to those of ammonite and/or nautiloid assemblages in the past.

Summary: During the Silurian and Devonian periods, cartilaginous fish developed specialized skeletal and dental features and improved their sensory systems. Fossils of a new species called Maghriboselache mohamezanei were discovered in Morocco, which shares key skeletal features with the iconic genus Cladoselache. Phylogenetic analysis reveals the evolutionary relationship between different shark families, indicating that the initial radiation of crown chondrichthyans occurred in the Late Devonian. The discovery of this new stem holocephalan provides insights into the sensory specialization and ecological diversity of early chondrichthyans.
