“…Nevertheless, it is possible that the isolated osteoderms and carapace fragments referred to P. jaguaribensis by Moreira (1971) and Porpino and Bergqvist (2002) may be dubious. While the isolated osteoderms resemble elements forming longitudinal rows near the lateral border of the carapace in P. tuberculatus (e.g., Burmeister 1870-1874) and P. intermedius (Zurita et al 2011b), the main figures of the supposedly mid-dorsal carapace fragments of P. jaguaribensis share intriguing similarities with the cephalic shield of other species of Panochthus. This new interpretation calls for a detailed revision of P. jaguaribensis.…”

“…The latter differ in features relating to the caudal tube, but share a strikingly similar carapace morphology (see Cruz et al 2011;Zurita et al 2011b), thus making specific assignments of isolated carapace material difficult. Although the osteoderm here assigned to Panochthus cf.…”

“…Porpino and Bergqvist (2002) criticized this new allocation, arguing that the Ensenadan species Panochthus intermedius also presents well-developed, large main figures. However, as in other species of Panochthus, the main figures in P. intermedius are limited to the anterior and posterior portions of the carapace, and decrease in size towards the mid-dorsal region (Castellanos 1941;Zurita et al 2011b). By contrast, the carapace fragments of P. jaguaribensis (see Moreira 1971;Porpino and Bergqvist 2002;Porpino 2009) are thought to belong to the mid-dorsal region (Moreira 1971;Porpino 2009), and display fully developed main figures which are more closely spaced and proportionally larger than in P. intermedius (Porpino 2009).…”

RESUMENPanochthus es uno de los géneros de gliptodóntidos de mayores dimensiones y más ampliamente registrado en el Pleistoceno del sur de América del Sur. Una reciente revisión demostró que alberga seis especies distribuidas cronológicamente de la siguiente manera: P. intermedius y P. subintermedius (Pleistoceno tempranoPleistoceno medio, Ensenadense); P. tuberculatus y P. frenzelianus tienen sus biocrones limitados al Pleistoceno medio-Pleistoceno tardío (Bonaerense-Lujanense), mientras que P. greslebini y P. jaguaribensis solo pueden referirse al Pleistoceno sensu lato. En la presente contribución se da a conocer el registro más antiguo de Panochthus, representado por el material MMP 5171, procedente del Plioceno tardío (Aloformación Playa Los Lobos, Formación Chapadmalal; Chapadmalalense; Biozona de Paraglyptodon chapalmalensis) de la localidad de Mar del Plata, Buenos Aires, Argentina. El material consiste en un gran fragmento de coraza dorsal y en varios trozos de osteodermos asociados, asignables a una especie indeterminada de Panochthus. Uno de los caracteres más significativos es la presencia, a nivel de la superficie expuesta de los osteodermos, de figuritas que siguen un evidente patrón reticular, solo observable en Panochthus. Desde el punto de vista bioestratigráfico, es llamativa la ausencia de registros de Panochthus en la Edad Marplatense (Plioceno tardío-Pleistoceno temprano).Palabras clave: Panochthus; Chapadmalalense; Plioceno; Pleistoceno; Argentina ABSTRACTPanochthus is one of the largest sized and most frequently recorded genera of Pleistocene South American Glyptodontidae. A recent taxonomic revision shows that the genus includes six species: P. intermedius and P. subintermedius (early Pleistocene-middle Pleistocene), P. tuberculatus and P. frenzelianus (middle Pleistocene-late Pleistocene), whereas P. greslebini and P. jaguaribensis only can be referred to the Pleistocene sensu lato. In this contribution the oldest record of the genus Panochthus (MMP 5171) is presented and described. The remains came from the late Pliocene (Playa Los lobos Aloformation, Chapadmalal Formation; Chapadmalalan; Paraglyptodon chapalmalensis Biozone) of the Mar del Plata, Buenos Aires province, Argentina. The material is represented by a considerable fragment of dorsal carapace and some associated osteoderms, which are assignable to an indeterminate species of Panochthus. One of the most significant characters in the exposed surface of the osteoderms is the presence of a clear "reticular" pattern, a character only observed in Panochthus. From a biostratigraphic viewpoint, it is remarkable the absence of records of Panochthus in the Marplatan Age/Stage (late Pliocene-early Pleistocene).

“…Its fossil record spans the late Miocene to the late Pleistocene (Zamorano 2012). The genera Panochthus Burmeister, 1866, Nopachtus Ameghino, 1888and Propanochthus Castellanos, 1925 were traditionally included within this tribe (Castellanos 1942, Hoffstetter 1958, Paula Couto 1979, McKenna and Bell 1997, Zurita et al 2011, Zamorano 2012; however, in recent cladistic analyses they do not form a natural group (Zamorano andBrandoni 2013, see. Zamorano et al 2013).…”

The genus Panochthus represents the last lineage of "Panochthini" recorded in the Pleistocene. This genus has a wide latitudinal distribution in South America, and in Brazil it occurs in the southern and northeastern regions. In this paper we describe new material (isolated osteoderms and caudal tube fragments) assigned to Panochthus from the state of Rio Grande do Sul (southern Brazil) and discuss some taxonomic issues related to Panochthus tuberculatus and Panochthus greslebini based on this material . The occurrence of P. greslebini is the first for outside the Brazilian Intertropical Region. In addition, we describe new diagnostic features to differentiate the osteoderms of P. greslebini and P. tuberculatus. Unfortunately, it was not possible to identify some osteoderms at the species level. Interestingly, they showed four distinct morphotypes characterized by their external morphology, and thus were attributed to Panochthus sp. Lastly, we conclude that in addition to P.tuberculatus registered to southern Brazil, there is another species of the genus, assignable to P. cf. P. greslebini. Our analysis reinforce the reliability of caudal tube characters for the classification of species of Panochthus.
