another giant

25 February 2016

At http://phys.org/print375349033.html … glypodonts, like all armadilloes, originate from a common ancestor around 35 million years ago. The glypodont is a very large version of the armadillo and lived during the Late Plaeistocene – at the same time as giant elephants, giant grould sloths, giant elk and deer, and giant forms of lots of other animals. At the end of the Ice Age all these large mammals became extinct – why? Why did they grow to such a large size? It is almost reminiscent of the Jurassic era – when small dinosaurs of the Triassic became larger versions of the same animal. Why was this?
