su indicazione del Prof. Rodolfo Carosi (Università di Torino e Presidente SGI) vi segnaliamo l'ultimo podcast di Geology Bites (Conversations about geology with researchers making key contributions to our understanding of the Earth and the Solar System):
Steve Brusatte (University of Edinburgh) on the Dinosaurs That Survived the AsteroidDi seguito troverete il messaggio dell'ideatore, Oliver Strimpel, e il link al sito web di Geology Bites.
Cordiali saluti,
La Segreteria SGI
Hello, listeners,
I just posted my episode with Steve Brusatte on the dinosaurs that survived the asteroid. Brusatte is Professor of Palaeontology and Evolution at the University of Edinburgh and author of The Story of Birds.
It is widely known that birds are dinosaurs, but perhaps less well known (I didn't know) that most of the bird species living when the asteroid struck were wiped out. In the podcast, Brusatte describes what the fossil record tells us about the survivors — beaks rather than teeth, very rapid maturation, digestive systems with a crop and gizzard, and small body size. He then speculates on how each of these traits would have helped them withstand the post-impact cataclysm and the ensuing period of cold and darkness.
I hope you enjoy listening.
Oliver
