When dinosaurs dominated, the Earth was not overcome by a greenhouse period, but experienced rapid fluctuations in temperature and sea level change that resulted in a balance of the global carbon cycle, new research into a missing link in climatology reveals. The study is being published in the March issue of Geology.
fossil wood
All credit to this finding goes to fossilized wood. Yes, it is by using high-resolution stable-isotope analysis from 95-million-year-old fossilized wood that the terrestrial carbon cycle with that from deep-sea records has been precisely correlated. Gröcke and his team had collected these woods from Nebraska.
