Research Interests

  • Paleoclimates of Pennsylvania Age eurypterid trackway of western Pennsylvania

Geology Discoveries  

  • Section research and collecting continues to investigate late Devonian and Carboniferous climate change and its implication to biotic evolution and extinction. During this episode of global climate change from the late Devonian through the late Pennsylvanian or 65 million years of time, global climatic cooling and warming had a profound affect on Earth's paleoenvironments, sea level, extinctions, and evolution. Preliminary evidence (invertebrate fossils) collected from the Carboniferous reefs of the Bridger Range of Montana, New Mexico, and Oklahoma, suggests an apparent biotic recovery from the marine extinctions of the Late Devonian Ice House climate.
  • Research on the geology of the classic Carnegie Museum Dinosaur Quarries in Sheep Creek, Wyoming, and Earl Douglass (Dinosaur National Monument), Jensen, Utah, continues.

Western Pennsylvania Discoveries  

  • The investigation continues of the rocks of the Pittsburgh region for evidence on late Pennsylvanian climate change and how it might affect tetrapod (vertebrate) evolution during the Carboniferous.
  • A reinvestigation of the holotype euryterid trackway in Elk County, Pennsylvania, is underway.
