Late Cretaceous domatia reveals the antiquity of plant–mite mutualisms in flowering plants
<p>Mite houses, or acarodomatia, are found on the leaves of over 2,000 living species of flowering plants today. These structures facilitate tri-trophic interactions between the host plant, its fungi or herbivore adversaries, and fungivorous or predaceous mites by providing shelter for the consumers. Previously, the oldest acarodomatia were described on a Cenozoic Era fossil leaf dating to 49 million years in age. Here, we report the first occurrence of Mesozoic Era acarodomatia in the fossil record from leaves discovered in the Late Cretaceous Kaiparowits Formation (76.6–74.5 Ma) in southern Utah, USA. This discovery extends the origin of acarodomatia by >25 million years, and the antiquity of this plant–mite mutualism provides important constraints for the evolutionary history of acarodomatia on angiosperms.</p>
Data from: Does morphology reflect osteohistology-based ontogeny? A case study of Late Cretaceous pterosaur jaw symphyses from Hungary reveals hidden taxonomic diversity
With a single complete mandible and 56 mandibular symphyseal fragments of various sizes, the Late Cretaceous Hungarian azhdarchid material has been considered one of the most extensive monospecific pterosaur assemblages in the world. Representing a broad size range, these elements have been thought to demonstrate a developmental series of Bakonydraco galaczi. As such, they were ideal to test whether absolute size and/or morphology reliably indicate relative ontogenetic stages in this pterosaur. Forty-five specimens were selected for multivariate morphometrics and classified into four size classes. After acquiring the morphometric data set, we thin-sectioned eight symphyses representing all size groups and classified them into relative ontogenetic stages based on qualitative microstructural inspection prior to quantitative histological analyses. Microstructural characters suggestive of developmental state were then quantified for intra- and interindividual uni- and multivariate analyses to test the correspondence among the results of qualitative and quantitative analyses. In contrast to our expectations, histological features identified the smallest specimen as an adult and not an early juvenile. The substantial size difference between this specimen and other adults, along with its distinct microanatomical and histological features, implies the presence of at least two pterosaur taxa in this symphysis assemblage. This hypothesis is further supported by multivariate morphometrics, which separate the smallest symphyses from all other specimens that form one continuous group. Although the latter group also shows considerable size variability in corresponding ontogenetic stages, this suggests developmental plasticity rather than the presence of even more taxa, and indicates that symphysis size and morphology are poor indicators of skeletal maturity in these animals. Hence, bone histology is an important independent test of the assessment of ontogenetic stage using size and morphology.

Late Cretaceous (Cenomanian-Turonian) ocean deoxygenation variability in response to idealized orbital configurations
<p>This dataset contains ocean and ocean biogeochemistry outputs (NetCDF files) from modeling experiments with realistic Cenomano-Turonian paleogeography and various set of idealized Earth' orbit confiurations (Eccentricity, Obliquity, Precession) . The set of simulation targets the ocean oxygenation response to variation in orbital parameters (Sarr et al. 2022) . The simulations have been run using the IPSL-CM5A2 General Circulation Model (Sepulchre et al. 2020 - IPSL-CM5A2 – an Earth system model designed for</p> <p>multi-millennial climate simulations, GMD) and offline version of PISCESv2 model (Aumont et al., 2015 - PISCES-v2: an ocean biogeochemical model for carbon and</p> <p>ecosystem studies, GMD). It includes 6 ocean-atmosphere simulations and 6 ocean biogeochemistry simulations. Data are monthly averages over the last 100 years of the simulations.</p>
