This group focuses on the paleobiodiversity and paleoecology of terrestrial ecosystems during the Mesozoic era (252-66 Ma), with emphasis on those time intervals best represented in the fossil record of Catalonia (bony remains, eggs and ichnites)—in particular, the last dinosaurs of Europe and associated faunas, in order to model the ecosystems of the Late Cretaceous before the K-T extinction that wiped out non-avian dinosaurs and other terrestrial vertebrates.

The composition of the Mesozoic Research Area is currently the following:

Dr. Àngel Galobart (Research Area Head)
