What secrets lie hidden in the jaws of a dinosaur?
It turns out that the enamel of dinosaurs’ fossilized teeth contains oxygen isotopes that provide clues about the early Earth’s atmosphere. An international research team used their newly developed method to investigate the climate and photosynthesis during the age of the dinosaurs: https://www.uni-goettingen.de/en/3240.html?id=7874

Cosmic dust holds clues to Earth’s ancient atmosphere
Tiny particles of rock and metal have been raining down on our planet from space since time immemorial. An international research team discovered that these fossilized micrometeorites can help reconstruct the atmosphere of the past: https://www.uni-goettingen.de/en/3240.html?id=7871

Where is over 99% of the world’s gold hidden?
It’s actually deep underground locked away in the Earth’s metallic core. However, researchers at our Uni discovered traces of precious metals in volcanic rocks on the islands of Hawaii which must have come from the Earth’s core: https://www.uni-goettingen.de/en/3240.html?id=7808. Their data shows material from the core, including gold and other precious metals, is leaking into the Earth’s mantle above.
