Trachycalyptus is a dubious[1] extinct genus of glyptodont. It lived during the Early Pliocene, and its fossilized remains were discovered in South America.
Like all glyptodonts, Trachycalyptus had a heavy body protected by a sturdy armor composed of osteoderms fused together. It had wrinkled and strongly punctuated osteoderms; the central figure was mainly distinguished by a lower density of small holes on its surface. The absence of radial groove allows to distinguish it from other genera of glyptodonts. The tail was protected by a caudal tube, characterized by the presence of wrinkled osteoderms with numerous vascular perforations, without differentiation of the peripheral area. There were three pairs of large lateral osteoderms on the tail.
