Did Eremotherium laurillardi Supplement its Diet with Sea Weed?

Eremotherium laurillardi, a species of giant ground sloth, apparently was abundant along the Georgia coast during the Sangamonian Interglacial (~132,000 BP-~118,000 BP).  Fossils of this species have been found at 7 of the 9 known coastal fossil sites of Pleistocene Age. It was really a spectacular beast growing as large as 18 feet long and weighing 6000 pounds.  When it sat on its haunches, it was even taller than a mammoth.  It disappeared from the state when the climate turned colder, probably some time between ~75,000 BP-~30,000 BP.  The fossil record is too incomplete to determine exactly when this species succombed to the cold in this region.  Eremotherium continued to exist in South America until the end of the Pleistocene.  Two other species of ground sloths  were better adapted to the cold and likely lived in Georgia as recently as 11,000 BP.  Jefferson’s ground sloth (Megalonyx jeffersonii) and Harlan’s…
