Abstract: Taphonomic processes may filter in a biased manner the tiny fraction of leaves preserved as fossils. A common perception is that large leaves are underrepresented; this is based both on intuition (large leaves are more likely to break apart) and some observations of extant vegetation. Characterizing leaf area correctly is critical for reconstructing climate and for studying evolutionary and biogeographic patterns. In extant dicotyledonous angiosperms, leaf area generally scales with… Expand
Reconstructing leaf area from fragments: testing three methods using a fossil paleogene species.
TLDR
Improved methodology to estimate leaf size from fossil fragments is provided, with great potential to improve physiognomy-based paleoenvironmental reconstructions and the interpretation of the fossil record. Expand
Paleoclimate and paleoecology of the latest Eocene Florissant flora of central Colorado, U.S.A.
Abstract The uppermost Eocene Florissant Formation of central Colorado, U.S.A. contains a diverse flora and fauna preserved in lacustrine facies and represents a key episode in Earth historyExpand
The Ravenscrag Butte flora: Paleoclimate and paleoecology of an early Paleocene (Danian) warm-temperate deciduous forest near the vanishing inland Cannonball Seaway
Abstract The Ravenscrag Butte flora in southwestern Saskatchewan, Canada, provides a record of an early Paleocene (Danian) forest ecosystem that followed the K-Pg boundary event. Plant macrofossilExpand

Resolving Australian analogs for an Eocene Patagonian paleorainforest using leaf size and floristics.
TLDR
The legacy of LH is evident not only in subtropical and tropical Australia but also in tropical montane Australasia and Southeast Asia, reflecting the disparate histories of surviving Gondwanan lineages. Expand
USING FOSSIL LEAVES AS PALEOPRECIPITATION INDICATORS : AN EOCENE EXAMPLE
Estimates of past precipitation are of broad interest for many areas of inquiry, including reconstructions of past environments and topography, climate modeling, and ocean circulation studies. TheExpand
Towards understanding the fossil record better: insights from recently deposited plant macrofossils in a sclerophyll-dominated subalpine environment
TLDR
An intrinsic representativity index is developed that provides a more accurate picture of the relationship between the leaf assemblages incorporated in the sediments and the abundance of these species in the source vegetation. Expand
Sensitivity of leaf size and shape to climate: global patterns and paleoclimatic applications.
TLDR
It is demonstrated that the inclusion of additional leaf traits that are functionally linked to climate improves paleoclimate reconstructions and illustrates the need for better understanding of the impact of phylogeny and leaf habit on leaf-climate relationships. Expand
COMPARISON OF LEAF SAMPLES FROM MAPPED TROPICAL AND TEMPERATE FORESTS: IMPLICATIONS FOR INTERPRETATIONS OF THE DIVERSITY OF FOSSIL ASSEMBLAGES
ABSTRACT We characterize forest floor leaf litter and transported leaf samples from several depositional environments in both a temperate and a tropical forest to provide well-characterized modernExpand

DISTRIBUTION OF POTENTIAL MACROFOSSILS IN LAKE DOBSON, TASMANIA
TLDR
The most important features affecting leaf deposition in the lake were the prevailing wind direction, the presence of lakeside or overhanging vegetation, and leaf sinking rates. Expand
The leaf-area shrinkage effect can bias paleoclimate and ecology research.
TLDR
The findings indicate that the amount of shrinkage is driven by variation in leaf area, leaf thickness, evergreenness, and woodiness and can be reversed by rehydration. Expand
Fossil leaf economics quantified: calibration, Eocene case study, and implications
TLDR
Reconstructed MA in the fossil species is negatively correlated with levels of insect herbivory, whether measured as the proportion of leaves with insect damage, theportion of leaf area removed by herbivores, or the diversity of insect-damage morphotypes, and these correlations reflect fundamental trade-offs in plant-herbivore associations.

Developmentally based scaling of leaf venation architecture explains global ecological patterns.
TLDR
Vein scaling relationships can explain the global biogeographical trend for smaller leaves in drier areas, the greater construction cost of larger leaves and the ability of angiosperms to develop larger and more densely vascularised lamina to outcompete earlier-evolved plant lineages. Expand
