Paleontologists Ted Daeschler and Neil Shubin describe their fossil finds of aquatic, early limbed animals:
Hynerpeton with its powerful forelimbs; the thick-jawed
Densignathus rowei; Sauripterus with its muscular fin about the size of a tennis racket head; and the very large and ferocious lobe-fin fish
Hyneria. Excerpted from an interview filmed for
Evolution: "Great Transformations."
