Doedicurus clavicaudatus, an extinct glyptodont, was a massive armored mammal from the Pleistocene epoch. It lived in South America and featured a large, domed shell and a heavy, spiked tail used for defense. As a herbivore, it roamed grasslands, playing a role in shaping the vegetation.

Doedicurus clavicaudatus was native to South America, primarily inhabiting regions that are now part of Argentina, Uruguay, and Brazil. Fossil evidence suggests it was distributed across the Pampas region, as well as the eastern and southern parts of the continent, extending into parts of Uruguay and southern Brazil.

Doedicurus clavicaudatus lived during the Pleistocene epoch, a period characterized by fluctuating climate conditions, including glacial and interglacial periods. It primarily inhabited open grasslands and savannas, which were prevalent in its native range at the time.

This species occupied an ecological niche as a large herbivore, feeding on a variety of vegetation available in grassland and savanna ecosystems. Its robust body and armored exterior suggest adaptations for grazing and protection against predators. The species was likely well-suited to the open terrains of the Pampas and similar environments, where it could efficiently forage and move across large areas.
