Resumen:
Tinamous, one of the earliest diverging living avian lineages, consists
of a Neotropical clade of palaeognathous birds with a fossil record
limited to the early Miocene?Quaternary of southern South America. Here,
we conduct a comprehensive, morphology-based phylogenetic study of the
interrelationships among extinct and living species of tinamous.
Morphological data of fossil species are included in a matrix of 157
osteological and myological characters of 56 terminal taxa. The
monophyly of most recognized genera is supported by the results of the
analysis. The cladistic analysis also recovers the traditional
subdivision between those tinamous specialized for open areas
(Nothurinae) and those inhabiting forested environments (Tinaminae).
Temporal calibration of the resultant phylogeny indicates that such a
basal divergence had already taken place in the early Miocene, some 17
million years ago. The placement of the fossil species within the
open-area (Nothurinae) and the forest-dwelling (Tinaminae) tinamous is
also consistent with the palaeoenvironmental conditions inferred from
the associated fauna.
