a-dinosaur-a-day:Inspired by speaksforthebreeze cladograms for Diapsida and Mammalia, I decided to do my own with Chordata - especially since some of their clade names were out of date (as well as clade placement, since the genetic analysis of Testudines (turtles) placed them as more closely related to archosaurs than to lepidosaurs ^_^)I used Ornithodira instead of Avemetatarsalia and Lepidosauria instead of Lepidosauromorpha simply to make the words fit neatly - even though I would have preferred to have Lepidosauromorpha to better match Archosauromorpha. Still, nothing about this is incorrect; I simply don’t use every single clade name (and to have done so would have been… impossible). Names in all caps are groups that dinosaurs/birds are a part of. The image is obviously compressed for tumblr; I’ve uploaded it on Deviantart as well and you can find it here: http://dinolove453.deviantart.com/art/Cladogram-of-Chordata-549407880 I used Wikipedia as reference for most of it; the paper that found testudines to be part of Archosauromorpha used both fossil and genetic evidence; you can find it here.

Let me know what you think and if I should do another (probably for Dinosauria)! -- source link
