Carbon-cycle perturbation in the Middle Jurassic and accompanying changes in the terrestrial paleoenvironment

Carbon-cycle perturbation in the Middle Jurassic and accompanying changes in the terrestrial paleoenvironment

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...
