I thought this bizarre statement must have been a typo, until this post…
…and realized that you really do hold to this unteathered chronology.
Hippo’s have been noted ifrom near the very beginning of hieroglyph writing before dynastic Egypt over 4500 years ago. Before that, there is pottery depicting hunting of the hippopotamus 5500 years ago..
One of Egypt’s principle gods, Taweret, was a chimera with the body of a hippo. Interesting to this discussion is that she came equipped with a crocodile tail, which may have influenced the imagery associated with hippo’s.
Hippo figurines were very common in ancient Egypt, and these were generally decorated with the associated reeds and lotus plants as referenced in Job, which I remind you, you still have not acknowledged.
Those stumpy legs can speed up 20 - 30 km per hour of charging belly. Hundreds of people are killed every year by hippo’s, making it Africa’s most dangerous large animal, despite being vegetarian. Again - Job 40:16

what power in the muscles of its belly!
Most hippo species are extinct, but a few million years for the large modern one. Most equine species are also extinct. You can figure out mules on your own. Here is a video for hippo evolution:
