• Removed colours of the clades. I know of no colouring system used in cladistics in such a way. Changed colours of geochronologic units to official colours.
• Birds are now part of the Theropoda
• Put Maniraptora in a more basal position, changed the name in the balloon to Deinonychosauria
• Presented Ceratosauria as a sister group, not a basal group of the Theropoda
• Made Prosauropoda and Sauropoda sister groups instead of presenting the first as the ancestors of the second
• Removed the suggestion that the Sauropoda declined in importance during the Cretaceous
• Made the Heterodontosauridae the first group to split off the main branch of the Ornithischia
• Merged Hadrosauridae, Iguanodontidae and Hypsilophodontidae into one group: Euornithopoda. The first two are paraphyletic anyway.
• Merged Psittacosauridae and Ceratop(s)ia. The first is part of the second group.
• Added the names of the basal groups Cerapoda and Genasauria

Explanation: MWAK argued the diagram originally uploaded by Zureks (based on a Polish encyclopaedia) contains outdated views and also plain mistakes. We think this version is better in line with current cladistic views on Dinosaur evolution.. Das Originalbild kann hier eingesehen werden: Evolution of dinosaurs by Zureks.svg: .
