Mid-Cretaceous pCO(2) based on stomata of the extinct conifer Pseudofrenelopsis (Cheirolepidiaceae)
- Abstract:
-
Stomatal characteristics of an extinct Cretaceous conifer, Pseudofrenelopsis parceramosa (Fontaine) Watson, are used to reconstruct atmospheric carbon dioxide (pCO2) over a time previously inferred to exhibit major fluctuations in this greenhouse gas. Samples are from nonmarine to marine strata of the Wealden and Lower Greensand Groups of England and the Potomac Group of the eastern United States, of Hauterivian to Albian age (136-100 Ma). Atmospheric pCO2 is estimated from the ratios between...
