Ted Daeschler and Neil Shubin: Early Tetrapod Fossils
In this transcript of an interview filmed for Evolution: "Great Transformations," Ted Daeschler and Neil Shubin describe the discovery and significance of some of their key fossil finds.
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."
Describe the combination of observation, comparison, and inference that Drs. Daeschler and Shubin use to reconstruct the habits of early tetrapods based on the shoulder girdle.
Discuss the importance of the diversity of fossil fishes and early tetrapods that lived during the same time period.
Academic standards correlations on Teachers' Domain use the Achievement Standards Network (ASN) database of state and national standards, provided to NSDL projects courtesy of JES & Co.
We assign reference terms to each statement within a standards document and to each media resource, and correlations are based upon matches of these terms for a given grade band. If a particular standards document of interest to you is not displayed yet, it most likely has not yet been processed by ASN or by Teachers' Domain. We will be adding social studies and arts correlations over the coming year, and also will be increasing the specificity of alignment.
