I had read at the time of the film's release that the The "Star Wars" Imperial Walker's form was based on a Ice age mega mammal:
Indricotherium transsouralicum*
Height: 16ft (4.7m)
Lived: 30 million years ago - 25 million years ago
Also known as Baluchitherium or Paraceratherium. Indricotheres were
the largest mammals to ever walk the earth. Depending on the source, these
overgrown rhinos were thought to weigh between 11 and 20 tons.
