2. Macroevolution & mass extinctions
Fossil specimens based systematics & morphology
Fossils from outside of Alabama
Fossils from Alabama: I work on fossils from Alabama, as well. in the photos above, you are seeing a rare fish bone from Mississippian limestone, a skull of Cretaceous marine reptile mosasaur, a large foot print of early reptile-synapsid from Pennsylvanian rocks, and a shoulder bone of large Cretaceous sea turtle.
Non-vertebrate paleontology: I am also interested or involved in invertebrate and plant fossils.
