  1. Pseudo science at its best. Totally ridiculous . They see a few fragments of bones and then invent some new whale species with legs out of it. Just a complete joke that anyone takes this seriously. They have replaced real science with wishful imagination and artist drawings. Just pathetic.

  2. This doc is so good, thank you so much for your work it's very nice to see this as a peruvian

  3. The animal looks a bit like Nomu from My Hero Acadamia. Can "Nomu" be worked into it's scientific name?
