![]() ![]() Patagonykus puertai, while MCF-PVPH-102 is considered an indeterminate Patagonykinae. Likewise, certain morphological evidence allows hypothesizing that Alvarezsaurus calvoi represents a growth stage earlier than skeletal maturity. Makovicky and collaborators that Achillesaurus manazzonei is a junior synonym of Alvarezsaurus calvoi is rejected. ![]() ![]() In this sense, the hypothesis proposed by P. Different evolutionary and paleobiological studies were carried out in order to elucidate functional and behavioral aspects.Īlvarezsaurus calvoi (MUCPv-54), Achillesaurus manazzonei (MACN-PV-RN 1116), Patagonykus puertai (MCF-PVPH-37) and Bonapartenykus ultimus (MPCA 1290) are valid species due to the presence of many autapomorphies. A phylogenetic analysis and a discussion about the taxonomic validity of the recognized species and the taxonomic assignment of the materials MCF-PVPH-38, MCF-PVPH-102 and MPCN-PV 738 are presented. (MCF-PVPH-102), Alvarezsaurus calvoi (Holotype, MUCPv-54), Achillesaurus manazzonei (Holotype, MACN-PV-RN 1116), Bonapartenykus ultimus (Holotype, MPCA 1290), and cf. Patagonykus puertai (MCF-PVPH-38), Patagonykinae indet. It includes a detailed osteological description of specimens of Patagonykus puertai (Holotype, MCF-PVPH-37), cf. This Doctoral Thesis presents an exhaustive review of the Patagonian alvarezsaurids (Dinosauria, Theropoda). Su basamento se encuentra conformado por rocas metamórficas, ígneas y sedimentarias, cuyas edades van desde el Silúrico-Devónico hasta el Triásico Tardío (Digregorio y Uliana 1980 Franzese et al. Esta cuenca ha sido establecida como de tipo retroarco multiepisódica (Mpodozis y Ramos, 1989), cuya secuencia se encuentra conformada por sedimentos marinos, continentales y de tipo transicional (Casamiquela, 1964 Digregorio y Uliana, 1980 Bonaparte et al., 1984 Albino, 1986 Bonaparte, 1987 Uliana y Biddle, 1988 Barrio, 1990 Powell, 1992 Salgado y Coria, 1996 Salgado y Azpilicueta, 2000 Coria, 2001 de la Fuente et al., 2001 Hugo y Leanza, 2001 Martinelli y Forasiepi, 2004 Coria y Salgado, 2005 Franzese et al. Estos sedimentos aflorantes se pueden observar en las siguientes provincias: Neuquén, sur de Mendoza, noroeste de Río Negro y suroeste de La Pampa, con un área total de 120.000 km2 (Digregorio y Uliana, 1979 Legarreta y Uliana, 1999 Howell et al., 2005). ![]()
