Northern Map Turtles, Graptemys geographica, are a long-lived riverine species of conservation concern. We examined carapace morphology of Northern Map Turtles at Mount Union, a major turtle nesting ...

Long before dinosaurs roamed the earth, the oceans were full of creatures known as ammonites. Scientists have now created a number of robotic ammonites, to see how the different shell shapes they ...

For years, scientists have tried to crack a mathematical mystery: Is there an equation that can perfectly describe each and every bird egg? Variable shell shapes complicated things. But it turns out ...

Robotic ammonites, evaluated in a university pool, allow researchers to explore questions about how shell shapes affected swimming ability. They found trade-offs between stability in the water and ...
