Summary: The chondrocrania morphology of birds is generally uniform in major features, with some variation in specific regions. Unique chondrocranial anatomy in certain bird species reflects their distinct adult skull shape. Differences in chondrification sequence can distinguish between different bird clades, with conservation seen in certain areas of the chondrocranium.

Summary: Studies have shown that plasticity in developmental trajectories plays a significant role in the origin of novel traits and species divergence. However, finding evidence for plasticity-led evolution in the fossil record is challenging. This study used high-resolution computer tomography techniques to map changes in the developmental trajectories of planktic foraminifera, and found a correlation between variation in development and the appearance and reproductive success of descendant species.

Summary: Understanding the ontogeny of a taxon is essential for its taxonomy and evolution. The use of neurocentral suture closure sequence as a method for determining maturity in extinct reptiles is debated, especially for species not closely related to crocodilians. Delayed neurocentral closure in Hyperodapedontinae may be a paedomorphic heterochronic process, while open neurocentral sutures do not always indicate immaturity in extinct reptiles. The ancestral state of Archosauria likely follows the crocodilian closure pattern, but delayed closure may have originated independently in several archosauromorph lineages.

Summary: We analyze the relationships between two click beetles Paulusiella Lobl, 2007 and Analestesa Leach, 1824 (=Cebriognathus Chobaut, 1899) that cannot jump. By using mitochondrial genomes and nuclear genes, we find that Paulusiella is closely related to Hemiops Laporte, 1838 (Hemiopinae) and Analestesa belongs to the Cardiophorinae subfamily. This study provides new molecular evidence for the evolutionary relationships of click beetles. Rating: 7 out of 10.

Summary: Studies on vertebrates have provided important insights into craniofacial morphogenesis, but little is known about the patterning of distinct facial morphologies during development. Comparative models between related species, such as mammals, can help uncover the origin of species-specific patterning. The use of single-cell multi-omics techniques allows for detailed investigation into the cellular and molecular processes underlying craniofacial evolution.

Summary: Through 3D finite element analysis and study of mandibles from various tyrannosaurid genera, it was found that smaller juvenile and subadult tyrannosaurs experienced higher simulated stresses in the lower jaw. In adult tyrannosaurs, mandible strength increased with ontogeny and showed an evolutionary trend of enhancement. These results may indicate different predatory strategies used by juvenile and mature tyrannosaurids.

Summary: A comprehensive revision and phylogenetic analysis of fossil mysticetes provides the basis for a chronology of their diversification events. The results indicate that Mysticeti originated approximately 38 million years ago, Chaeomysticeti around 28 million years ago, and Balaenomorpha around 23.3 million years ago. Furthermore, the study explores the relationships between diversification events, ecological turnovers, and geodynamic events, showing that different combinations of biotic and abiotic factors are correlated to each diversification event.

Summary: During ontogenetic development, insects undergo drastic changes, particularly in the pupa stage. However, there are limited depictions of pupae in the literature. This study presents the first discovery of a fossil pupa in the lacewing group Mantispidae, observed in Eocene-aged Ukrainian Rovno amber. The study compares the morphology of pupae and adults of Mantispidae, revealing greater diversity in adult morphology and suggesting an indirect development of forelegs throughout ontogenetic stages.

Summary: Assessing the taxonomic importance of the suture line in shelled cephalopods is crucial for understanding their diversity. The study on Nautilus and Allonautilus reveals that conch geometry is useful in distinguishing species and genetically distinct populations can be identified based on this feature. The results are applicable to closely related fossil cephalopods but may not extend to more distantly related forms like ammonoids.

Summary: Understanding the links between development and evolution is a major challenge in biology. This study introduces a new approach, called Energy Proxy Traits (EPTs), to quantify organismal development as high-dimensional landscapes of energy spectra in video. The findings show that changes in event timings can influence the high-dimensional phenotypic space, providing a new perspective on the importance of developmental event timing in evolution.

Summary: Thatchtelithichnus traces are commonly found on the outside surface of plastral bones of Eocene geoemydid turtles and freshwater turtles, but have also been discovered on a partial grey whale mandible from the Belgian Pliocene. These traces, possibly attachment scars of aquatic ectoparasites, penetrate into the cancellous bone with a maximum depth of about 2 mm. Recent studies suggest that similar structures may be produced by barnacles attaching to mammal bones exposed on the seafloor, contributing to a better understanding of trace formation processes.

Summary: The study investigates the decline of nautiloids during the Cenozoic period and its correlation with the appearance of pinnipeds and cetaceans. The results show that nautiloids became extinct in areas where pinnipeds appeared, except for the agile nautiloid Aturia. The decline of nautiloids in the American Pacific coasts coincided with the development of oxygen minimum zones (OMZs) in the region. It is hypothesized that the spread of pinnipeds played a major role in driving nautiloids into their present-day refuge in the central Indo-West Pacific Ocean.

Summary: Notocetus vanbenedeni is a valid platanistoid taxon with intermediate morphological features. Peruvian specimens cannot be assigned to this species based on anatomical differences and phylogenetic analyses. Notocetus vanbenedeni is the only suction-feeder recorded in the early Miocene of Patagonia and one of the smallest odontocetes. The abundant records of Notocetus vanbenedeni in a freshwater-influenced inner shelf environment suggest an early preference for such protected habitats.

Summary: Islands have long been recognized as unique environments for evolutionary divergence, resulting in variations in body size, such as dwarfs and giants. Incorporating data from 1231 extant and 350 extinct species, our study spanning 23 million years reveals that island mammals with extreme body sizes are most vulnerable to extinction. Moreover, the arrival of modern humans has significantly accelerated extinction rates, leading to the near complete eradication of these iconic examples of island evolution.

Summary: The fossil record of the cephalopod genus Nautilus was incorrectly classified as other genera in the 20th Century by influential taxonomists. However, recent recognition and correction have revealed that these fossils actually belong to the Nautilus genus. Fossils from Taiwan and Indonesia represent the northernmost and southernmost Neogene records, respectively, for Nautilus in the Indo-Pacific region. It is important to gather more specimens to determine the variability within these Neogene taxa.
