Beyond the game
The real Cotylorhynchus
Its head was tiny in relation to the enormous barrel-shaped trunk. That body is interpreted as space for a digestive system capable of processing abundant plant matter.
It was one of the great terrestrial vertebrates of its time. The volume of the body is interpreted as space to process abundant plant matter. This relationship between food and body shape helps to understand a silhouette that is not very similar to current herbivores.
This grouping describes evolutionary relationships. Its members share ancestors; they do not form a chain in which one must turn into another.
