There are literally zero videos about Potamotherium. Small mammals really get ignored by the media and documentary makers. Sometimes small mammals show up in animated movies, but Potamotherium has not shown up as yet. Instead of extolling this fact, I think it is important to look at a similar, but certainly different, semi-aquatic mammal that lived during a similar time-frame but in a different area. The animal in question is Puijiladarwini, a definitively diagnosed basal seal capable of walking on land (not flopping about like a seal/sea lion). Enjoy learning about this animal in this video and see if you can take what we have learned about Potamotherium and compare it with Puijila!
