Bunostegos - a new version?

Looks like Bunostegos was even weirder than we thought. A new study found that the animal didn't walked with sprawled arms as its relatives, but with the four limbs in an upright posture. This is unique for a pareiasaur, and Bunostegos was probably the first animal to walk in this way.

Here, I modified my recent illustration of this species, to update the posture.
