Answer Monday!

This past week on Fossil Friday, I presented a fossil from our fan Gerald Wilgus that was as big as a hippo! But it wasn't a hippo. It was the rhino, Teleoceras. Dave Puskala was the first to figure this out. 

From UC Santa Cruz:

"The extinct rhinoceros, known as Teleoceras, ranged from Florida to the West Coast from about 17 million years ago until about 4.5 million years ago. Its semi-aquatic lifestyle, first suggested by its body shape, has been disputed by some researchers. But evidence preserved in fossil teeth now indicates that in some areas, at least, Teleoceras did spend much of its life in the water."

Thanks to Gerald for the photo and congrats to Dave for figuring this out.
