A natural history museum is really two museums, and when you’re in one of them, you can hardly imagine the other. I don’t know how many times I’ve wandered around the halls of the American Museum of Natural History, among the armored fish and the stegosaurs. But it wasn’t until I was a 26-year-old science writer that I had the chance to pass through to the other side. I wanted to learn about pterosaurs, those stork-faced, bat-bodied reptiles that soared for 150 million years. I found out about a Brazilian man named Alexander Kellner who was getting his Ph.D. at the museum, studying new fossils of pterosaurs from the Santana Formation. Kellner invited me to the museum, to take a look at the bones and talk about his ideas about what pterosaurs had actually been like in life.
