Using a Theoretical Ecospace to Quantify the Ecological Diversity of Paleozoic and Modern Marine Biotas
635079
By Novack-Gottshall, Philip M  Abstract.- The process of evolution hinders our ability to make large-scale ecological comparisons-such as those encompassing marine biotas spanning the Phanerozoic-because the compared entities are taxonomically and morphologically dissimilar.
