Dinosaurs (Reptilia, Archosauria) at Museo de La Plata, Argentina: annotated catalogue of the type material and Antarctic specimens

Abstract

A commented-illustrated catalogue of non-avian dinosaurs housed at Museo de La Plata, Argentina is presented. This represents the first commented catalogue of the La Plata Museum dinosaurs to be published. This includes the type material as well as Antarctic specimens. The arrangement of the material was made in a phylogenetic fashion, including systematic rank, type material, referred specimens, geographic and stratigraphic location, and comments/remarks, when necessary. A total of 13 type specimens of non-avian dinosaurs are housed at the collection of Museo de La Plata, including eight sauropods, one theropod, one ornithischian, and three ichnotaxa. There are four Antarctic specimens, one of which is a holotype, whereas other corresponds to the first sauropod dinosaur registered for that continent.

First evidence of Hadrosauropodus in Gondwana (Yacoraite Formation, Maastrichtian-Danian), northwestern Argentina

“…The bones remains have been related to Hadrosauridae indet (Casamiquela, 1964;Apesteguía and Cambiaso, 1999;Hill et al, 2002;Luna et al, 2003;Martinelli and Forasiepi, 2004;Cruzado-Caballero, 2014;Cruzado-Caballero and Coria, 2014), with the basal hadrosaurid Secernosaurus koerneri (Bonaparte et al, 1984;Prieto-M arquez and Salinas, 2010) and Lapampasaurus cholinoi (Ju arez-Valieri et al, 2010;Coria et al, 2012), and the hadrosaurine Willinakaqe salitranensis (Ju arez- Valieri et al, 2010;Coria, 2014). In Antarctica, hadrosaurids are limited to the Maastrichtian L opez de Bertolano Formation (Otero and Reguero, 2013). The fossil remains are fragmentary and scarce and were classified as Hadrosauridae indet (Rich et al, 1999;Case et al, 2000;Otero and Reguero, 2013).…”
