The source of sulfate in brachiopod calcite: Insights from μ-XRF imaging and XANES spectroscopy
Sign Up to like & getrecommendations! Published in 2019 at "Chemical Geology"
DOI: 10.1016/j.chemgeo.2019.119328
Abstract: Abstract Geochemical signatures preserved in sedimentary carbonate strata are often used as archives for paleoenvironmental reconstructions. However, diagenetic overprinting and/or muting of primary geochemical signatures complicates the interpretation of these data. To avoid this issue,… read more here.

DOI: 10.1016/j.palaeo.2020.109856
Abstract: Abstract Brachiopods, together with ammonoids, were collected bed-by-bed from several Lower Cretaceous pelagic sections and localities in the Bakony Mountains (Transdanubian Range, Hungary), dated by detailed ammonoid and nannofossil biostratigraphy. These yielded abundant and diverse… read more here.

DOI: 10.1111/let.12233
Abstract: During the Great Ordovician Biodiversification Event (GOBE), the number of marine invertebrate families more than tripled. Fundamental shifts in clade dominance and ecological structure led to the rise of the Palaeozoic Fauna and the second… read more here.

DOI: 10.3390/biology12040622
Abstract: Simple Summary Brachiopods have been thought to be in very low diversity in the Early Triassic for a long time. There are only several Olenekian brachiopod fauna reported worldwide, all of which are in very… read more here.

Multi-proxy assessment of brachiopod shell calcite as a potential archive of seawater temperature and oxygen isotope composition
Sign Up to like & getrecommendations! Published in 2023 at "Biogeosciences"
DOI: 10.5194/bg-20-1381-2023
Abstract: Abstract. Most of our knowledge of past seawater temperature history is based on δ18O values of calcium carbonate fossil shells. However, the determination of past temperatures using this proxy requires the knowledge of past seawater… read more here.
