I like this one from a 2015 paper by Allen et. al. It's not applicable everywhere, especially because of how weird croc coracoids are and due to taxa-specific discrete differences in orgins/insertions, but I think it's one of the best references for the major groups in Archosaurs

Lotosaurus, another oddity of the Triassic. A toothless, beaked, herbivorous and sail-backed Poposauroid pseudosuchian (the croc-line archosaurs) that lived during the Middle Triassic of China. There will be text over the upper side of the image

I made a quick hexapod dragon anatomy sheet for all your artisty needs. Its heavily based in archosaurs because archosaurus are the best animals. Please let me know if you have any questions.

Every time someone tells me “crocodiles are living fossils, they have never changed in millions of years” I go and reconstruct one of the MANY odd looking pseudosuchians (croc-line archosaurs) that will appear in my book
