Kraglievichia is an extinct genus of cingulate belonging to the family Pampatheriidae. It lived from the Late Miocene to the Early Pliocene, and its fossilized remains were discovered in South America.
Description
This animal looked like an enormous armadillo, with body dimensions comparable or larger than the modern giant armadillo ; its skull was 18 centimeters long. As for all its relatives, the pampatheres, the structure of the armor of Kraglievichia forbade it to curl up, as most modern armadillos does. The genus was characterized by the presence of four upper teeth and three lower teeth with an oval section, a characteristic differentiating it from the very similar but smaller Vassallia. The osteoderms of its carapace had an elevated axial area, underlined by two lateral longitudinal depressions.
Classification
The genus Kraglievichia was established in 1927 by Castellanos, for a species of fossil cingulate first described in 1883 by Florentino Ameghino. The type species, Kraglievichia paranense, is documented in the fossil records in Argentina and Uruguay. Some isolated osteoderms, with a morphology similar to those of Kraglievichia, but also to those of Pampatherium, have been described by Castellanos under the name Plaina intermedia. It is however probable that those fossils should in fact be attributed to the genus Kraglievichia.
Kraglievichia was a member of the family Pampatheriidae, a clade of cingulates very similar to modern armadillos, and closely related to them. Kraglievichia was a rather derived member of this group, potentially ancestral to the large Pleistocene genera Holmesina and Pampatherium.
