Summary: This study provides evidence for the presence of non-biting midges of the subfamily Chironominae in the Mesozoic, based on descriptions of rare amber inclusions. A previously reported record from Late Cretaceous Taimyr amber has been revised and confirmed, with a new find in Burmese amber extending the temporal boundary of the subfamily. The discovery of two new genera in amber specimens sheds light on the phylogeny and diversification tempo of the Chironominae and Pseudochironomini in the past.

Summary: We present evidence for the existence of non-biting midges of the subfamily Chironominae in the Mesozoic era, based on rare amber inclusions. The subfamily was previously reported in Late Cretaceous amber, but we revise and confirm that record, and also discover a new find in Burmese amber that pushes back the subfamily's temporal boundary to the mid-Cretaceous. We describe two new genera and provide insights into the phylogeny and diversification tempo of the Chironominae and Pseudochironomini.

Summary: Phoroid flies constitute an ancient lineage within Diptera, featuring diverse species like scuttle flies and less species-rich groups like flat-footed and ironic flies. A new species of the enigmatic Lebambromyia genus, Lebambromyia sacculifera sp. nov., is described from mid-Cretaceous amber in Myanmar, expanding the geographic and temporal distribution of the genus. The study of the fossil fly reveals a mix of ancient and modern features, with phylogenetic analyses suggesting a relationship with flat-footed and ironic flies but with uncertain placement.

Summary: Burmese amber is an important source for the study of taxonomy and evolution due to its rich collection of perfectly preserved insects. In this paper, the presence of a primitive genus of Keroplatidae, Paleoplatyura, is reported in Burmese amber for the first time. Three new species of Paleoplatyura are described, suggesting that this genus was already diverse in the Cretaceous period. The study confirms the existence of Paleoplatyura in the Mesozoic.

Summary: The newly described amber-embedded fossil represents an early species of the lizard family Agamidae, dating back to around 99 million years ago in northern Myanmar. This finding could serve as a calibration point for divergence-time analyses and challenges the view that agamids colonized Southeast Asia during the Paleogene.

Summary: This study reports the complete mitochondrial genome sequences of 12 Chironomus species and one Microchironomus species for the first time. The analysis of these mitogenomes, combined with previously reported ones, provides insights into the nucleotide composition, codon usage, selection pressure, and heterogeneity of Chironomus species. The phylogenetic relationships of Chironomus based on these mitogenomes were also reconstructed. The findings demonstrate the conservative nature of Chironomus mitogenomes in terms of nucleotide composition and gene order, enriching the existing knowledge of chironomid mitochondrial genomes and contributing to a better understanding of the evolutionary history of Chironomus.

Summary: Stempellinella gilkai sp. nov., a non-biting midge of the subfamily Chironominae, tribe Tanytarsini, from the Eocene is described based on the adult male. This study provides a comparison of significant characters to delimit fossil Stempellinella and discusses key features of antenna and hypopygium. A comparative analysis of extinct and extant Stempellinella representatives led to an amendment of the current generic diagnosis, with notes on the genus' paleoecology and species richness during the Eocene.

Summary: Bruchomyiinae is one of the seven subfamilies of Psychodidae, mainly found in tropical and sub-tropical regions. Fossils from the Cretaceous Myanmar amber show that this subfamily was abundant during that period. The discovery of three new species in the amber suggests that Bruchomyiinae was probably more diverse in the Mesozoic era than previously thought.

Summary: This study presents a detailed osteohistological analysis on Triceratops horridus and Triceratops cf. prorsus specimens, aiming to understand the growth and development of ceratopsids. The analysis reveals a distinct pattern of bone tissue growth in Triceratops limb elements, but also suggests that taxonomic ambiguity between Torosaurus and Triceratops cannot be solely resolved based on histological data.

Summary: This article presents a review of ammonoid specimens from the Berriasian and Valanginian age in Zacatecas, Mexico. The study includes updated museographic information, new images, and 3D models of the specimens. Taxonomic identification has revealed six species and two genera. Stratigraphic range data suggests that the specimens belong to the uppermost upper Berriasian to lower Valanginian interval, with several biozones identified. Additionally, a paleobiogeographic analysis indicates a clear affinity with contemporaneous ammonoid assemblages from the Mediterranean region.

Summary: In Europe, the fossil record of sauropods in the uppermost Cretaceous is mainly found in Spain, France, and Romania. Recently, a significant discovery of titanosaurs' teeth was made in Els Nerets, Spain, which contains the largest tooth sample from the Late Cretaceous in Europe. The teeth show distinct characteristics but cannot be attributed to any known European species. Based on tooth morphology and wear facets distribution, a new taxon is proposed.

Summary: This work proposes the application of magnetic surveying to study the cyclicity in sedimentary basins. Through measuring the total magnetic field and vertical magnetic gradient, the short-wavelength magnetic anomalies associated with the sedimentary sequence can be analyzed, providing information about the magnetic susceptibility and magnetic remanence of different sedimentary units. The cyclostratigraphic analysis reveals the existence of various cycles and enables the dating of the basin fill, offering new constraints for basin evolution.

Summary: Predator-prey interaction exerts significant selection pressure on the evolutionary pathways of both parties. This research presents a new dataset of gastropod drilling predation on molluscan prey from the Upper Cretaceous, highlighting the influence of drilling predation during this period. The study utilizes a hybrid method of surface sampling without physically breaking the host rock. Findings suggest that drilling predation was an established form of predation during the Late Cretaceous, yet remains understudied.

Summary: Conifer fossil woods from the Campanian Puntudo Chico Formation were studied, confirming the presence of Brachyoxylon currumillii and the introduction of Cupressinoxylon sp. cf. C. artabeae in the formation. The new specimens of Podocarpoxylon mazzonii suggest that this taxon is common in the Cretaceous to Eocene floristic assemblages. The growth-ring analysis of these fossil trees indicates their development under temperate and humid conditions, with slight sensitivity from year to year and a terminal event representing a cessation or retardation of cambial activity. Other paleoclimatic proxies suggest a temperate-warm and humid depositional environment with some semi-arid events in the Puntudo Chico Formation.
