A database of detrital zircon geochronology ages of Cambrian to Paleogene deposits in South China
Geoscience Data Journal, Volume 11, Issue 4, Page 405-413, October 2024.Here, we had collect a database about the South China Phanerozoic detrital zircon geochronology data, and we published the database in DDE. We marked Kernel density estimates, ɛHf(t) vs. U‐Pb ages and the best age‐based multidimensional scaling plot from South China. Abstract Complications of detrital zircons databases provide a means for statistically

The many ways toward punctuated evolution
Palaeontology, Volume 67, Issue 5, September/October 2024.Abstract Punctuated equilibria is a theory of evolution that suggests that species go through periods of stability followed by sudden changes in phenotype. This theory has been debated for decades in evolutionary biology, but recent findings of stasis and punctuated change in evolutionary systems such as tumour dynamics, viral evolution, and artificial

Papers in Palaeontology, Volume 10, Issue 3, May/June 2024.Abstract The documentation of cuticular micro‐ornament is vital for the taxonomic assignment of palaeoscolecids: vermiform lower Palaeozoic ecdysozoans interpreted as stem‐group priapulans or early diverging panarthropods. This is due to the absence of the character‐rich proboscis and tail hooks in palaeoscolecid material not from Burgess Shale‐type ...

An image dataset of fusulinid foraminifera generated with the aid of deep learning
Geoscience Data Journal, Volume 11, Issue 1, Page 46-56, January 2024.The first large image set of fusulinid foraminifera, containing 2,400 images of individual fossils covering all six fusulinid families, has been generated by an auto‐segmentation procedure. The procedure successfully segmented fusulinid individual images from literature figures and fossil thin‐slice photos with a deep learning technique (BlendMask ...

New biostratigraphic and chemostratigraphic data from the Chicotte Formation (Llandovery, Anticosti Island, Laurentia) compared with the Viki core (Estonia, Baltica) [PDF]
Estonian Journal of Earth Sciences, 2009 Due to the lack of biostratigraphically useful graptolites in the crinoidal and reefal Chicotte Formation on Anticosti Island (Québec, Canada), the precise chronostratigraphic position of the formation is not known. New stable carbon isotope and conodont
