Tricyclic diterpenoids and pentacyclic triterpenoids are nearly exclusively produced by
gymnosperms and angiosperms, respectively. Even though both classes of terpenoids have …

Plant-derived diterpenoids are commonly used as conifer-specific biomarkers and for
chemotaxonomic assignment or confirmation. Numerous studies have reported on the utility …

Seasonal changes in δ13C values for individual lipids from the leaves of several species of
tree have been studied in order to provide essential background information for use in future …

The carbon isotope composition (δ 13 C) of terrestrial plant biomarkers, such as leaf waxes
and terpenoids, provides insights into past carbon cycling. The δ 13 C values of modern …

Triterpenoids and their derivatives are ubiquitous in sediment samples. Land plants are
major sources of nonhopanoid triterpenoids; these terpenoids comprise a vast number of …

Plant-derived terpenoids, long recognized as biomarkers, can help reveal the major
taxonomic groups of land plants present in ancient environments, even if rocks and …

Plant wax n-alkanes are valuable paleoclimate proxies because their carbon (δ 13 C) and
hydrogen (δ 2 H) isotopes track biological and environmental processes. Angiosperms …

Plant biomarkers, such as terpenoids and leaf wax components (n-alkanes, n-alkanoic acids
and n-alkanols), are frequently found in sediments and can be used, often in association …

The degree of isotopic variation in fossil organic matter renders bulk δ13C signatures
strongly influenced by molecular isotopic heterogeneity. For example, in fossil wood the …

Terrestrial plant biomarkers and their carbon isotopes provide insights into carbon cycling,
paleovegetation and paleoclimate, ranging in scale from local to global. Over the past …
