Terror birds (Aves, Phorusrhacidae) comprise the most outstanding group of South American Cenozoic avifauna, and have been considered dominant predators. Terrestrial habits were inferred using reduction their forelimbs high body mass. Phorusrhacids functionally tridactyl with three relatively short digits II-IV a small, elevated digit I. The function ungual phalanges II debated, including utility for retention or stabbing prey. Incomplete lack preservation foot bones hampered understanding...
The Upper Miocene-Lower Pliocene Río Negro Formation (Río Province, Argentina) contains diverse and abundant continental trace fossils. purpose of this contribution is to recognize distinctive fossil assemblages in interdune lakes as response lake expansion contraction. deposits host 23 invertebrate, vertebrate, plant ichnotaxa that are linked the hydrological dynamics lake. During a highly subaqueous assemblage reflects an infaunal bivalve population living littoral zone with swampy...
This contribution reviews the worldwide record of canid and canid-like (creodont hyaenid) fossil footprints, taxonomy this type reports a new footprints from late Pleistocene Pehuen Co site southern Buenos Aires province, Argentina. On basis comparison proposed ichnogenera features modern felid set ichnogeneric ichnospecific taxobases are proposed. The ichnotaxonomic review includes Bestiopeda Vialov, 1965; Canipeda Panin Avram, 1962; Felipeda Pehuencoichnum Aramayo Manera de Bianco, 1987b...
Fossil tetrapod burrows from the Cerro Azul Formation (Late Miocene-Early Pliocene) of southwestern Buenos Aires Province, Argentina, are described and interpreted. The local sedimentary sequence is composed massive siltstone, with two interbedded calcareous palaeosols, that were deposited in a loessic plain under semiarid climate. burrow systems recognised as Maneraichnus pampeanum igen. isp. nov., an ichnotaxon typified by long ramps lead to main chamber located at bifurcation, chambers...
The Pehuen Co Paleoichnological site (Buenos Aires province, Argentina) contains one of the more diverse and well-preserved mammal bird fossil footprint assemblages from Late Pleistocene. purposes this paper were a detailed paleoenvironmental assessment footprint-bearing unit (middle member Agua Blanca Sequence) to date key stratigraphic surfaces constraint temporal development site. A total twenty-two sedimentological sections measured correlated five sediment remain samples dated by...
