No full textThis contribution reviews the worldwide record of canid and canid-like (creodont and hyaenid) fossil footprints, the taxonomy of this type of footprints, and reports a new record of canid footprints from the late Pleistocene Pehuen Co site of southern Buenos Aires province, Argentina. On the basis of the comparison of proposed ichnogenera and features of modern canid and felid footprints, a set of ichnogeneric and ichnospecific taxobases are proposed. The ichnotaxonomic review includes Bestiopeda Vialov, 1965; Canipeda Panin and Avram, 1962; Felipeda Panin and Avram, 1962; Pehuencoichnum Aramayo and Manera de Bianco, 1987b; Creodontipus Santamaría et al. 1989–1990; Tetrastoibopus Sarjeant and Langston, 1994; and Quiritipes Sarjeant et al. 2002. A key to discriminate these ichnotaxa is also proposed and the diagnosis of Canipeda emended. The new findings of canid footprints from Pehuen Co are indistinguishable from Pehuencoichnum gracilis Aramayo and Manera de Bianco, 1987b, and this ichnospecies is synonymized under Canipeda gracilis (Vialov, 1965). An emended diagnosis for C. gracilis is proposed. The most likely producer of C. gracilis from Pehuen Co is a medium-sized fox similar to the extant representatives of Lycalopex.Fil: Melchor, Ricardo Nestor.
