Organic matter enrichment mechanism, algae species and carbon cycle in the saline lacustrine basin during the Middle Eocene: A case study of the Dongpu Depression, Bohai Bay Basin

, 2023
 The paleoclimate, paleoenvironment, and algae species were investigated based on mineralogy and petrological characteristic, organic and inorganic geochemical, organic carbon isotopic (δ13Corg) and palynological assembles analyses. The results show that

Influence of the late Ordovician-early Silurian paleoenvironment and related geological processes on the organic matter accumulation and carbon isotope excursion

, 2023
 Although previous studies have shown that the paleoenvironment and geological processes contributed to the organic matter accumulation (OMA) and carbon isotope excursions (CIEs) during the late Ordovician–early Silurian, the dominated controlling factor

Morphological plasticity in the dentition of the lungfish Gnathorhiza from the Permian of Brazil: A population‐level geometric morphometric analysis

The Anatomical Record, EarlyView.
Abstract Dental plates are pivotal in the lungfish paleontological record, constituting highly mineralized structures resilient to diagenetic processes. This study provides a detailed description and quantitative shape analysis of 95 newly discovered Gnathorhiza sp. dental plates from the Middle–Late Permian Corumbataí Formation, Brazil.
