They are described as "hefty" and "huge herbivores", and yet the scale on the skeletons suggest they are the size of a rabbit?
The scale is for 100mm aka 10cm aka 4 inches.
The scale is 27px, the skeleton is 482px from snout to tail, for a suggested size of ~1.8m (5ft10).
I don't know where you live, but you've got pretty fucking huge rabbits if they're the size of an average bloke. Note that this: http://www.oubler.com/assets/userdata/news_media/1433158298.... is not a rabbit
