متن کاملThe Paleontological Society.
I am examining fossil plant specimens from the Blue Rim site of the Eocene (~50 Ma) Bridger Formation in southwestern Wyoming. This site is rare in that multiple plant organs are preserved together. By characterizing the flora, I can assess the diversity and complete a paleoclimate and paleoecological analysis. After using the funds provided by The Paleontological Society for field equipment, I...
متن کاملMorphological and developmental macroevolution: a paleontological perspective.
Evidence of the morphological evolution of metazoans has been preserved, in varying degrees of completeness, in the fossil record of the last 600 million years. Although extinction has been incessant at lower taxonomic levels, genomic comparisons among surviving members of higher taxa suggest that much of the developmental systems that pattern their bodyplans has been conserved from early in th...
