Resumen:
The earliest complete glyptodonts (Glyptodontidae, Cingulata) found belong to the Propalaehoplophorinae from Santa Cruz Formation (late Early Miocene, Burdigalian) in Patagonia (Argentina). Although several skulls and mandibles have been described from this formation, and assigned to five genera (Propalaehoplophorus Ameghino, Cochlops Ameghino, Asterostemma Ameghino, Eucinepeltus Ameghino, and Metopotoxus Ameghino), the fossil record and knowledge of juvenile specimens of glyptodonts are still poor. Here we provide a detailed morphological description of a mandible belonging to a juvenile specimen of a propalaehoplophorinae glyptodont from the Santa Cruz Formation, using micro-computed tomography (μm-CT) and SEM images. We compare the juvenile mandible with adult specimens, discussing the taxonomic assignment, the juvenile and adult mandibular and dental characters, and dental eruption and tooth wear.
