Plant Fossils: Glossopteris, Acer, Calamite, Metasequoia, Fern,
Petrified Wood, Annularia, Sequoia Cone, Carbonized Wood
Fascinating facts about Plant Fossils: * Plants bearing small leaves or none at all tend to indicate hot, dry regions
whereas plants with very large leaves tend to indicate much wetter environments.
* Plants bearing leaves with toothed edges tend to indicate cooler climates,
whereas those with smooth edges tend to indicate regions of hotter climates.
These observations would most likely hold true within ancient environments as well as those within modern environments.
