Although 2020 was an all around shit show for the world, there were a few interesting bits of paleontology. Perhaps none more interesting than this potential overhaul to pterosaur reconstructions. Now, I haven’t really written anything about pterosaurs on my site yet (aside from some basic rundowns of news stories), so this marks an interesting way of christening the occasion. Pterosaurs are a fascinating group of critters that showcase yet another example of how animals can get airborne. They are also enigmatic in their origin and evolution.
One thing that we seemed to be confident about for a long time now is that pterosaurs had fuzz. It wasn’t fur in the mammal sense, and it sure as hell wasn’t feathers (more on that in a minute), but instead a third (or fifth, when counting arthropods and some plants) form of insulative covering. At least, that’s what I thought we knew up until about last year.
It may just turn out that this seemingly rock-solid interpretation of pterosaur outer coverings has been wrong all along.
