Paleobotany & Fossil Plants

Leaf margin analysis, stomatal indices, pollen diagrams, fossil wood anatomy, and phytolith morphology — reconstructing ancient climates and ecosystems from the plant fossil record.

Paleobotany deciphers Earth's deep botanical history by studying fossilized leaves, pollen, wood, and microscopic silica bodies preserved in sedimentary rocks. Because plants are sessile organisms exquisitely tuned to their environment, their fossils serve as high-fidelity paleoclimate proxies — recording temperature, atmospheric CO2, rainfall, and seasonality across millions of years.

These simulations let you estimate paleotemperature from leaf margin percentages, reconstruct ancient CO2 levels from stomatal density, build pollen percentage diagrams that reveal shifting vegetation zones, decode growth rings in petrified wood for paleoclimate signals, and classify phytolith morphotypes to infer grassland versus forest habitats.

5 interactive simulations

Leaf Margin Analysis & Paleotemperature

Estimate mean annual temperature from the percentage of entire-margined (smooth-edged) leaves in a fossil flora using leaf margin analysis

simulator

Phytolith Morphology & Habitat Reconstruction

Classify silica phytolith morphotypes from sediment samples to reconstruct grassland versus forest habitats through geological time

simulator

Pollen Percentage Diagram & Vegetation Reconstruction

Build a pollen percentage diagram from simulated core data and reconstruct shifting vegetation zones through time

simulator

Stomatal Index & Paleo-CO2 Reconstruction

Reconstruct ancient atmospheric CO2 concentrations from the stomatal index of fossil leaves using the inverse relationship between stomatal density and CO2

simulator

Fossil Wood Growth Rings & Paleoclimate

Analyze growth ring patterns in petrified wood to reconstruct paleoclimate seasonality, temperature, and precipitation
