HIGHLIGHTS

- PALEOENVIRONMENTS OF PAMPA-PATAGONIA TRANSITION

Late Holocene fossil pollen record from Zoko Andi 1 site reconstructs vegetation dynamics and palaeoenvironmental change at multiple spatial scales.

- BONE HISTOLOGY OF ARGENTINEAN PROTEROCHAMPSIDS

Proterochampsid histology indicates diverse growth modes and ecological specializations preceding early archosaur evolution.

- A NEW TITANOSAUR FROM URUGUAY

A new sauropod from Uruguay is described, allowing to establish correlations with Upper Cretaceous units from Argentina and Brazil.
