Redesing of TFIW: Toraton

Everyone in speculative evolution knows what is the Toraton a derived descendant of current turtles, which with the disappearance of most of the current megafauna, they were one of several animals which have taken that place, mainly as large herbivores in the swamps of the future earth. These are twice as tall as an elephant, and in weight, are showed to be the heaviest land animals that ever existed are, weighing 120 tons.

I must say that some parts of the desing for this animal are somewhat plausible, as the upstanding legs and lived in a swamp which gives a good food supply, however, some things are probably not reasonable like why its weight is so huge, why have a segmented carapace or how a turtle has been able to evolve to this type of niche. Do not get me wrong, turtles have shown a great ability to take certain niches and become part of the megafauna, however, something like Toraton seems that would emerge in environments where they were the only creatures in the world as a terraformed planet, since they are quite conservative and have not submitted a large morphological change in the last 200 million years, plus other types of vertebrates like lizards, little mammals or something else could take such niches in a short time (because there is not explanatio about if happened a new mass extinction event in the others 195 million years). Perhaps is the lack of explanation about its evolution or the events that led to its evolutinary path.

This Toraton that I call Barochelys (for the friends Stan), is a giant semi-aquatic turtle species that live in 80 to 100 million years in the future. The climate during this age is quite tropical, there is not more polar caps, so there are even tropical forests at the poles, however, the eath is dominated by a new class of vertebrates that took place in most of the continets, and the Toraton is just a strangeness between others animals. This species resembles the extinct softshell turtles, which lack a bony carapace. It has a length of about 4 meters long, it reaches a height of 3 meters and weighs about 3 tons, it spend some time mobilizing around the swamps, devouring the treetops, always in groups of several individuals.

Edit: Length change to a reasonable size and removal of the rounded and inflated shape of the plastron, also this is now part of the redesign of the Bengal Swamp fauna.
