Stable carbon isotope record of terrestrial organic materials for the last 450 Ma yr

The timing and magnitude of carbon isotope excursions is essential for understanding the global transfer of carbon among the oceansland, and atmosphere. Numerous studies have focused on data collection of stable carbon isotopes (δ13C) from marine sediments, and by extension to the atmosphere, but many fewer systematic studies have been conducted on land plants over long time intervals. We pursued three approaches to determining stable carbon...
