According to Wikipedia that is because the bird-hipped ones looked like modern birds and the names came before we realized the error.
Hooray!
Dinosaur translates to “terrible lizard” so retaining outdated terminology is on brand.
Was it before we know birds were related to dinosaurs at all? And while we’re at it: when did we find that out?
Quickly skimming Wikipedia Orthopoda (now synonymous to Ornithischia, bird hips) was coined in 1866. Birds from dinosaurs as an idea kinda gain traction during 1868. It was during 1870s when the famous full Archaeopteryx fossil was found is when it really get cemented. Missed it just by a few years.
yet another unrealistic body standard smh
If this doesn’t convince you that it’s all fake, I don’t know what will

Would you rather have lizard lips or lizard hips?
Clint’s Reptiles had a good video on this.
