SSP2.5
Paleozoic to Mesozoic stratigraphy, paleoceanography and paleoclimate (including Jean Baptiste Lamarck Medal Lecture by Isabel P. Montañez) (co-sponsored by IAS) 

This session aims to showcase an interesting diversity of state-of-art advances in all aspects of Cambrian to Cretaceous paleoceanography, paleoclimatology and stratigraphy. Within this broad topic we intend to invite an exciting range of contributions including, but not limited to, organic and inorganic geochemistry, sedimentology, (micro-)paleontology, and modelling. Inter- or multidisciplinary studies are also encouraged. The session will potentially be organized into thematic blocks to allow more in-depth exploration and discussion of topics.
