New information on Bonapartenykus (Alvarezsauridae: Theropoda) from the Allen Formation (middle Campanian-lower Maastrichtian) of Río Negro Province, Patagonia, Argentina clarifies the Patagonykinae body plan. by Jorge Gustavo Meso, Jonah Nathaniel Choiniere, Mattia Antonio Baiano, Stephen Louis Brusatte, Juan Ignacio Canale, Leonardo Salgado, Diego Pol, Michael Pittman

“…In this contribution, we describe new alvarezsaurid material and review previously reported alvarezsaurid specimens from the middle Campanian-lower Maastrichtian Allen Formation discovered at the Salitral Ojo de Agua locality in Río Negro province, Patagonia, Argentina. Although these specimens were collected at different times without precise original provenance information, here we gathered X-ray diffraction data of the associated sediments that now suggests that all of these specimens come from the same site and stratigraphic level as the holotype of the alvarezsaurid Bonapartenykus ultimus. …”

SISTEMAS FISIOGRÁFICOS DEL ÁREA NATURAL PROTEGIDA “VALLE CRETÁCICO”, PROVINCIA DE RÍO NEGRO by Romina Solorza, Marcos D. Mare

“…This paper is a revised and shortened version of the biophysical studies of carried out as a part of the interdisciplinary technical reports for the "Management Plan of the Protected Natural Area (PNA) Cretaceous Valley" of the Rio Negro Province. The physiographic systems study shows that there is a marked susceptibility to the erosion processes increase, especially gully erosion. …”

LOCALIZACIÓN DE NUEVOS ASENTAMIENTOS HUMANOS Y SECTORES PRODUCTIVOS EN LA MESETA PATAGÓNICA ARGENTINA by Luis Alberto Bertani, María de los Ángeles Tesoniero, Lorena Conejeros Bilbao

“…The present paper presents the evaluation of the possibility of a deep transformation in the area of the Patagonian plateau in the eastern sector of the Río Negro province, Argentina. The idea is based on a project to emplace an artificial lake to generate electricity in an absolute depression called “Bajo del Gualicho” (- 72,0 m asl), which would connect with the sea in the San Matías Gulf in the Atlantic Ocean, about 25 km away, to take advantage of the amplitude of tides existing in that place. …”
