Comentario acerca de “Explotación de aves voladoras en la estepa de Patagonia continental austral: cauquenes (Chloephaga sp.) en el sitio Laguna Las Vegas (cuenca media del río Coyle, Argentina), de Juan Bautista Belardi y Luciana Stoessel (2022), Relaciones 47(2).
Fossil vertebrates, especially mammals, of the Neogene–Quaternary of Central Argentina were fundamental to the construction of time and rock-time scales and the knowledge of the biotic evolution of southern South America. The poverty of fossiliferous localities constrained with radiometric and/or paleomagnetic data heavily complicated the correlati...
MICROMAMMAL COMMUNITY CHANGES DURING LATE HOLOCENE–ANTROPOCENE IN SOUTHEASTERN BUENOS AIRES PROVINCE (ARGENTINA). The qualitative and quantitative taxonomic composition of the micromammal assemblages (including didelphimorphs, chiropterans, and rodents) derived from trophic activity of strigiform birds is analyzed. The studied samples have been col...
Pelecanus paranensis sp. nov., a new pelican (Aves, Pelecanidae) from the marine Upper Miocene Paraná Formation, which crops out in the Province of Entre Ríos, Argentina, is described. This record constitutes the first report of a fossil pelican from Argentina and the southernmost from South America. The holotypical specimen consists of a very larg...
A major barrier to advancing ornithology is the systemic exclusion of professionals from the Global South. A recent special feature, Advances in Neotropical Ornithology, and a shortfalls analysis therein, unintentionally followed a long-standing pattern of highlighting individuals, knowledge, and views from the Global North, while largely omitting...
