Smith was the co-author, with Claud William Wright, of a twelve-part series of monographs on British echinoid fossils of the Cretaceous. [ 9 ] [ 10 ] Smith's research is not strictly limited to echinoderms but also deals with methods of inferring patterns in evolutionary development from the fossil record.
This includes groups that are significant in paleontological contexts, abundant in the fossil record, or have a high proportion of extinct species. Special notations are explained below: [ ! ]: Indicates clades that are important as fossils or abundant in the fossil record. [ – ]: Indicates clades that contain a large proportion of extinct ...
The subclass Euechinoidea includes almost all living species of sea urchin, with fossil forms going back as far as the Triassic. [1] [2] Taxonomy
