Simosuchus

Information
Simosuchus clarki was a species of herbivorous or omnivorous, terrestrial crocodylomorph that dug throughout and occupied the subcontinent of Madagascar during the Late Cretaceous, and is approximately 70 million years old. Found from the Maevarano Formation, it probably coexisted with other Mesozoic creatures, like the hyperpredatory abelisaurid Majungasaurus crenatissimus, the dromaeosaur Rahonavis ostromi, the titanosaurian sauropod Rapetosaurus krausei, and the giant pacman frog Beelzebufo. For this, it had good reason to be armored, and it sacrificed mobility to have an inflexible osteoderm shield covering the top of its back and tail to protect itself from potential predators, such as the similarly-sized Rahonavis. Curling its head back and legs inwards would have minimized the soft tissue exposed.
