Tonnicinctus
Tonnicinctus is an extinct species of Pampatherid that lived in Argentina during the Pleistocene and Holocene. Description. "Tonnicinctus" inhabited cool grassland regions. It was a medium-sized Pampathrerid, smaller than its better-known relatives like "Pampatherium" and "Holmesina". It is distinguishes from other Pampathreres by: osteoderms which are intermediate in thickness between "Pampatherium" and "Holmesina"; very wide anterior and lateral margins with several large and deep foramina; wide and uniform marginal elevation in the fixed osteoderms and very narrow marginal elevation in movable and semi-movable osteoderms of the scapular and pelvic buckler.
