Carbon-cycle perturbation in the Middle Jurassic and accompanying changes in the terrestrial paleoenvironment
- Abstract:
-
Carbon-isotope analyses of fossil wood from the Middle Jurassic Ravenscar Group, Yorkshire, NE England, reveal a significant excursion toward light isotopic values (δ13C change of -3 to -4‰) at about the Aalenian-Bajocian boundary (∼174 Ma). A positive carbon isotopic excursion is also shown for the middle Bajocian (∼170 Ma) but is less clearly defined. These isotopic patterns are very similar to the few published marine carbonate records available for this time, in particular one based on be...
