The Lower Devonian deposits develop well and are widely distributed in the South China Plate, Its Early Devonian flora shows high endemism especially at the generic level. The Posongchong flora from the Lower Devonian of Yunnan, as a representative working area, has a total of 28 genera and 37 species of plants and over 70% genera are endemic. Several regional floras other than Yunnan have been discovered from southern China, as Pingyipu of Jiangyou, Yangling of Chongyi, and Shiqiao of Cangwu.
A new angiosperm fruit, Dilcherifructus mexicana gen. et sp. nov, from the Middle Jurassic of Mexico. This is the currently earliest record of angiosperms in the North America, and its geographical position indicates that angiosperms were already widespread in the North Hemisphere during the Jurassic. This new information prompts a rethinking on the history of angiosperms and related hypotheses.
The Cretaceous paleo-ocean has experienced multiple phases of Oceanic Anoxic Events (OAEs), which characterized by organic carbon enrichment, geochemical indicator anomalies and fossil assemblage changes. It includes three events, namely OAE 1, OAE 2 and OAE 3.
Intensive volcanism has been considered a major driver of environmental/climatic changes throughout Earth history, including global warming due to excessive volcanogenic CO2 emission, acidification, ozone depletion etc., which in turn have been perceived important killing mechanisms of mass extinctions. However, direct evidences of the linkage between volcanism and paleoenvironmental /paleoclimatic perturbations are still lacking.
Angiosperms may be distinguished from their gymnosperm peers bytheir flowers,and thus a flower is a good proxy of fossil angiosperms. However, flowers and their parts are usually too frail to be preserved in the fossil record. This makes the origin of angiosperms and their flowers the foci of controversy in botany.
Alienopteridae were originally proposed as a new insect order (Alienoptera) in 2016, and this family was considered as one of the most peculiar insects in Burmese amber.
Myrmecomorphy is a phenomenon in which some animals mimic ants morphologically and behaviorally, and belongs to a special kind of anthropomorphic behavior, which is very widely distributed in nature.
During the Late Permian to Early Triassic, benthic marine redox conditions in the Shangsi area varied on both short-term and long-term time scales. This study has scientific implications for revealing the spatial and temporal distribution of anoxic events, and the importance of oceanic anoxia in the end-Permian mass extinction (EPME).
Mineralization of Amber Insects Provides New View of Amber TaphonomyInclusions in amber can preserve organisms’ organs, tissues and cells in high fidelity, and are known as “exceptionally preserved” fossils.2022-02-28
