Integrated biostratigraphy of the Maastrichtian-Danian sequence in the southern Tethys with insights into paleoenvironmental implications [PDF]
Scientific ReportsThe Cretaceous-Paleogene (K/Pg) sequence offers a global perception of the paleoecological evolution in the southern Tethys realm. High-resolution calcareous nannofossil and dinoflagellate cyst analyses were conducted on subsurface Maastrichtian-Danian ...

Evidence of Cheliped Autotomy and Regeneration in the Lower Miocene Crab <i>Achelous monspeliensis</i> From Portugal. [PDF]
Ecol EvolCrab autotomy with evidence of regeneration is described for the first time in the fossil record. Autotomy is a defensive behavior that affects more males than females of Achelous monspeliensis and may be related to mating season. ABSTRACT Autotomy—the voluntary shedding of a limb as a defensive response to predation, intraspecific aggression, or ...

Geophysical Monograph Series, Page 305-323., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Lower Jurassic calcareous nannofossil taxonomy revisited according to the Neuquén Basin (Argentina) record [PDF]
Journal of Micropalaeontology, 2022 Standard Early Jurassic biostratigraphic studies were performed in the boreal and Tethys realms (western Europe and northern Africa), and biozonations from these areas are the most accurate of the world. Comparatively, investigations in the Pacific realm

Calcareous Nanofossil of Post-Gondwana Sequence in Southern Banda Arc, Indonesia
JGEET: Journal of Geoscience, Engineering, Environment and Technology, 2021 The presence of calcareous nannofossils in samples of the Post-Gondwana sequences (Kolbano and Viqueque sequence) gives guidance about the relative age of the study area located in the Outer Banda Arc, namely Timor, Rote, and Sawu Island.
