For years, Oliver Jagoutz, assistant professor of geology at MIT, and Max Schmidt, professor of geology at the Swiss Federal Institute of Technology in Zurich, have searched the Himalayan Mountains for clues about the formation of the Earth’s continental crust. Their work has led to discoveries that put the material of the Earth’s molten mantle on par with that of meteorites. In this podcast, Jagoutz and Schmidt discuss the implications of this discovery, and other aspects of the Earth’s formation, for understanding our planet’s evolution.
The Takeaway visited our new exhibition, Pterosaurs: Flight in the Age of Dinosaurs, with the curators, paleontologists Mark Norell and Alex Kellner. Listen as they discuss pterosaur discoveries, debate whether the animals had fur or feathers, and try out the pterosaur flight simulator.
In the run-up to Pterosaurs: Flight in the Age of Dinosaurs, which opens this Saturday, we’re introducing a few interesting species from this amazing flying reptile group. First up: Pterodaustro guinazui, which lived about 100 million years ago.
Pterodaustro’s lower bill included hundreds of extremely long, needlelike teeth. Paleontologists infer that this species’ lower teeth may have allowed it to filter feed by scooping up water and straining it for tiny aquatic animals, much like flamingos do today.
