RESEARCH DESCRIPTION: 

Dr. Leslie's research interests are at the intersection of paleontology with stratigraphy and geochemistry using conodont microfossils. Only the small tooth-like elements, composed of calcium phosphate, of conodont animals are usually preserved, which makes understanding the paleobiology of these extinct eel-like creatures challenging. Dr. Leslie and his student use conodonts to determine the age of the rocks that contain them, and study the oxygen and carbon isotopes in the conodonts and the rocks to interpret paleoclimate.
