The idea of animals other than chordates having recognizable, somewhat vertebrate-like bones/bony elements is still a rather odd one to grasp. Scientifically, it makes sense. Intuitively, it's strange. Scientifically, birds are an offshoot of non-avian dinosaurs, and so are dinosaurs, which is fairly easy to grasp when one looks at accurate skin depictions of dinosaurs and looks at their skeletons. In the same way, though...humans are technically a really weird, derived kind of fish.
