Brontosaurus was ruled an invalid species name in 1903…Pterosaurs, such as the pterodactyls, have never been considered dinosaurs. There are are all archosaurs, a division of reptiles than includes the crocodilians.The big change in recent decades is the idea that birds should be classed in there with dinosaurs. There’s still a lot of debate about that.It says much about the sorry state of science education that a lot of people don’t get the core idea that science is all about finding past errors, correcting itself, and improving the body of knowledge. If science wasn’t always saying “oops, we had that wrong, but now we’ve learned more” then it wouldn’t be working.
