Tanystropheus, a strange marine reptile that lived alongside dinosaurs, has puzzled paleontologists since its discovery in the mid-1800s. At first, scientists mistook the species for flying reptiles, due to their extremely elongated neck bones. Only later did they realize that the vertebrae framed a neck so long that it looked like evolution was trying to create a cartoon.
Now, a new paper seeks to answer a nearly 170-year-old question: Wasn’t such a long and awkward neck a liability?
