Life histories of Mesozoic polar mammals and the evolution of mammalian traits ...
We propose sub-micron resolution X-ray computed tomography of growth structures in the teeth and jaws of Mesozoic mammal fossils to establish the evolution of mammalian traits: elevated basal metabolic rate (BMR) and growth rate, and one phase of tooth replacement (diphyodonty). We will study fossil...
