Phlyctaenopyga is an extinct genus of glyptodont. It lived from the Late Miocene to the Early Pliocene, and its fossilized remains were discovered in South America.

Description

Like all glyptodonts, this animal had a robust carapace, formed by osteoderms fused together, covering a large part of its body. Phlyctaenopyga was a medium-sized glyptodont, not exceeding two meters in length. Its carapace was made of osteoderms whose central figure was surrounded by two or three rows of peripheral figures ; the second row was complete only in a few osteoderms in Phlyctaenopyga ameghini, while the third row was always incomplete. The central figure of the osteoderms was convex and protruding, almost hemispherical. The skull was very short and broad, especially in the snout area. The osteoderms covering the head were practically devoid of ornamentation.

Classification

The genus Phlyctaenopyga was first described in 1944 by Cabrera, for a species of Late Miocene glyptodont first ascribed to the genus Plohophorus , P. ameghini. Cabrera also attributed the species Nopachthus trouessarti to this genus, as Phlyctaenopyga trouessarti. Those two species were mainly distinguished by details of their osteoderms.

Phlyctaenopyga was a glyptodont, a clade of cingulates related to the modern armadillos, with a rigid carapace. Phlyctaenopyga seems to have been close to the genera Nopachthus and Plohophorus , within the tribe Sclerocalyptini.

<i>Stegotherium</i> Extinct genus of mammals in the armadillo order of xenarthrans

Stegotherium is an extinct genus of long-nosed armadillo, belonging to the Dasypodidae family alongside the nine-banded armadillo. It is currently the only genus recognized as a member of the tribe Stegotheriini. It lived during the Early Miocene of Patagonia and was found in Colhuehuapian rocks from the Sarmiento Formation, Santacrucian rocks from the Santa Cruz Formation, and potentially also in Colloncuran rocks from the Middle Miocene Collón Curá Formation. Its strange, almost toothless and elongated skull indicates a specialization for myrmecophagy, the eating of ants, unique among the order Cingulata, which includes pampatheres, glyptodonts and all the extant species of armadillos.

<i>Neosclerocalyptus</i> Extinct genus of mammals

Neosclerocalyptus was an extinct genus of glyptodont that lived during the Pliocene, Pleistocene, and Holocene of Southern South America, mostly Argentina. It was small compared to many Glyptodonts at only around 2 meters long and 360 kilograms.

Peltephilidae is a family of South American cingulates (armadillos) that lived for over 40 million years, but peaked in diversity towards the end of the Oligocene and beginning of the Miocene in what is now Argentina. They were exclusive to South America due to its geographic isolation at the time, one of many of the continent's strange endemic families. Peltephilids are one of the earliest known cingulates, diverging from the rest of Cingulata in the Early Eocene.
