Egg shape changes at the theropod bird transition, and amorphometric study of amniote eggs
The eggs of amniotes exhibit a remarkable variety of shapes, from spherical to elongate and from symmetrical to asymmetrical. We examine eggshell geometry in a diverse sample of fossil and living amniotes using geometric ...
