Two new #GSABulletin papers place Kenya’s Buluk fossil site within the Miocene climate optimum, with paleosols showcasing an open-canopy woodland where early apes and monkeys thrived: geosociety.co/Lukens-et-al geosociety.co/Lukens-et-al-2 Image: Fig. 7 from the first paper #Paleoclimate #Isotopes

A huge thank you to everyone who stopped by the Paleontological Society Booth at GSA Connects this year! We had a fantastic time chatting with everyone🫶 #GSAConnects2026 #Paleontology #Paleo #Fossil #Denver

Using magnetostratigraphy, biostratigraphy, environmental magnetic records, and geochemical analyses, Shyu et al. developed the first age-depth model for the Poty Quarry, Paraíba Basin, NE Brazil, spanning the Cretaceous–Paleogene (K/Pg) boundary. geosociety.co/Shyu-et-al Image: Figures 2A–2C
