Short summary
The mid-Cretaceous (ca. 121 to 94 Ma) was characterized by a generally warm climate punctuated by supra-regional to global phenomena of widespread ocean anoxia. In this work we present the first complete record of temperature and fertility variations through the mid-Cretaceous in the western Tethys based on calcareous nannofossils. The new record indicates that temperatures and fertility were rather fluctuating but mostly independently, and they were not systematically associated with anoxia.
