The Brazilian giant tortoises have four pairs of costals, five vertebral scutes, eleven pairs of marginals, and a big, unbroken supracaudal. The front and the back marginals of the tortoise are somewhat serrated in the facade and the back of juvenile Brazilian giant tortoises. The carapace of the Juvenile Brazilian giant tortoise is yellowish tan to dark tan or even black color at the borders of the scutes. The areola in every scute of the animal is pale yellow, light brown or orange in color and merges into the darker shell top.
