I assume you mean classification here, full biology is a lot more. I wouldn't describe cladistics as hookum/voodoo. It's a quite well defined and successful method when used correctly, and has been in wide spread us since way before the 80ies. The only problem is that it didn't really work for micro organisms, which is the majority of living things because they all look very similar. Sequencing has changed that, and that's why we see so many changes to the tree of life now (in fact it's not even a pure tree anymore) For the specific problem of pterosaurs (which this article is about) sequencing doesn't help at all because there is no DNA. It's still all only bones and cladistics.
