Ordovician graptolite biostratigraphy of the Röstånga-2 drill core (Scania, southern Sweden)
GFF, 2020The graptolite biostratigraphy of the 116.11-m-long Röstånga-2 drill core from Scania, southern Sweden, includes the Darriwilian (Middle Ordovician) Holmograptus lentus, Nicholsonograptus fasciculatus, Pterograptus elegans, Pseudamplexograptus distichus ...

The middle Homerian biotic crisis resulted in the almost complete eradication of graptolites. The shale-dominated Kosov Quarry section, central Bohemia, preserves the most complete graptolite record across the crisis in peri-Gondwanan Europe.

The graptolite succession of the YD‐1 drill core provides a new view into the lower Silurian (Llandovery) biostratigraphy of the Yichang region on the Yangtze platform of China. A thick succession of black to greenish, fine to silty shales and siltstones

Chitinozoan, graptolite and organic-rich immature Upper Ordovician mudstone was artificially matured using closed hydrous pyrolysis. The pyrolysis was performed at isothermal temperatures of 310-350 °C at 10 °C increments for 72 h. This temperature range
