Glyptodont fauna in Arizona

Two million years ago the southeastern Arizona landscape was filled with giant furry, armored, glyptodonts that had migrated from South America to mix with a northern fauna of mammoths, mastodonts, camels, horses, ground sloths, saber-tooth cats, armadillos, anteaters, and tortoises, to create a unique 'glyptodont fauna.'

Dave Gillette, paleontologist and curator at the Museum of Northern Arizona has authored a wonderful description of this creature and its prominent role for nearly 2 million years in this region, as the feature article in the AZGS Spring issue of Arizona Geology online.
