Confirmed: the Chicxulub impact caused the K/T extinction
Members of the IUCA and the Team of Micropaleontology of the Universidad de Zaragoza, along with 38 other specialists, publish in the prestigious Journal
Science a review corroborating the theory that the impact of a large meteorite in the Yucatan peninsula caused the mass extinction event of the Cretaceous/Tertiary boundary. The alternative hypothesis supporting a more gradual extinction due to multiple causes (mainly to the unusual volcanic activity of the Deccan, India) is weakened.

New causes of the extinction that occurred in the oceans after an asteroid impact 65 million years ago
The study, published by Laia Alegret, Ellen Thomas and Kyger C. Lohmann, shows that the photosynthesis and the food chain in the oceans recovered much earlier than previously suggested. A rapid episode
of surface ocean acidification after the impact may have been the main cause of
extinction of numerous species, while taxa that lived at the deep sea floor survived.
