Flipside of a dinosaur mystery: 'Bloat-and-float' explains belly-up ankylosaur fossils
Flipside of a dinosaur mystery: 'Bloat-and-float' explains belly-up ankylosaur fossils A scientist with the Canadian Museum of Nature has answered a long-standing mystery about why fossils of ankylosaurs—the "armoured tanks" of the dinosaur world—are mainly found belly-side up. In doing so, he has ruled out three other competing theories involving clumsiness, predation, and the effects of bloating as seen in armadillo roadkills. https://phys.org/news/2018-02-flipsi...ly-up.html#jCp |
