In North America, fossils of duckbill dinosaur are abundant. So, Longrich did a double take when he was visiting the Natural History Museum of Marrakesh in Morocco and came across the 66-million-year-old jawbone of a previously undocumented duckbill species. In fact, paleontologists once thought duckbill dinosaurs were aquatic, but that theory eventually fell out of favor. But over millions of years, these once-in-a-million-year events will happen on average once every million years.”To better understand the migrations of duckbill dinosaurs, Longrich and his colleagues reconstructed their evolutionary tree. And then finally this European lineage, one branch of that evolutionary tree, jumps into Africa.”Longrich's team dubbed the new species Ajnabia odysseus.
