Is reversed bipedalism plausible?

[jnstuart]

The question reminds me of the book (somewhere in my library) “The Snouters: Form and Life of the Rhinogrades.” Surely if we humans can imagine a vertebrate lineage that involves incredible adaptations of the nose for various life styles, evolution could probably come up with a reversed bipedal creature. Whether it would be adaptive for a vertebrate to go down that path is another question.
