The seawater carbon inventory at the Paleocene–Eocene Thermal Maximum
The Paleocene–Eocene Thermal Maximum (PETM)(55.6 Mya) was a geologically rapid
carbon-release event that is considered the closest natural analog to anthropogenic CO2 …

Nitrogen isotopes reveal independent origins of N2-fixing symbiosis in extant cycad lineages
Cycads are ancient seed plants (gymnosperms) that emerged by the early Permian.
Although they were common understory flora and food for dinosaurs in the Mesozoic, their …

[HTML][HTML] Constraining conifer physiological parameters in leaf gas-exchange models for ancient CO2 reconstruction
Leaf gas-exchange models are increasingly used to reconstruct ancient atmospheric carbon
dioxide (CO 2) concentrations. One of these widely used models, the Franks model, requires …

[HTML][HTML] Key traits of living fossil Ginkgo biloba are highly variable but not influenced by climate–Implications for palaeo-pCO2 reconstructions and climate sensitivity
The Ginkgoales, including the 'living fossil'Ginkgo biloba, are an important group for stomata-

No Evidence for a Large Atmospheric CO2 Spike Across the Cretaceous‐Paleogene Boundary
Currently, there is only one paleo‐CO2 record from plant macrofossils that has sufficient
stratigraphic resolution to potentially capture a transient spike related to rapid carbon …

Quantitative critique of leaf‐based paleo‐CO2 proxies: Consequences for their reliability and applicability
A variety of proxies have been developed to reconstruct paleo‐CO2 from fossil leaves.
These proxies rely on some combination of stomatal morphology, leaf δ 13 C, and leaf gas …

An inter-comparison study of three stomatal-proxy methods for CO2 reconstruction applied to early Jurassic Ginkgoales plants
The inverse relationship between concentrations of CO 2 in the atmosphere (pCO 2) and the
stomatal index of vascular plant has been widely used to estimate ancient levels of …
