Bird to dinosaur

You could say something similar about pretty much all the General Question here.

It’s easier to post questions here than to comb universities for experts in fields related to our idle questions.

If by “we” you mean birds, dinosaurs and humans, maybe the better analogy is to say we’re all “fish” (“bony fish” to be more specific). As Colibri noted, we don’t form a clade with Trilobites.
