Unfair as it is to award some 50-million-year-old clades with barely 100 species with individual attention while relegating clades that are over half a billion years old and comprise many thousands of species to a couple of paragraphs, vertebrates (in particular, dinosaurs) are the focus of this site. In any case, echinoderms are another group that does not vary much from timeline to timeline.
