About Alfio Alessandro Chiarenza

I am a vertebrate palaeontologist interested in macroecology, mass extinctions and dinosaur palaeobiology. To investigate these topics, I use fossils together with phylogenetic, biogeographic, statistical, and Earth System Modelling tools.

Long-term climatic changes did not cause the extinction of non-avian dinosaurs

The extinction of the dinosaurs, 66 million years ago, is one of the great unsolved mysteries of science. Although a sudden and catastrophic event (an asteroid impact, intense volcanic activity, or both) has been widely recognised as the most likely killing mechanism, some authors contend that environmental changes in the Late Cretaceous were responsible for a long-term decline in the number of dinosaur species. A novel approach, merging fossils, big data and machine learning, may help untangle the conundrum.
