| Fossil remains of birds belonging to the family Phorusrhacidae were studied in several museums of South America, North America and Europe, the main objective being to characterize this family and solve the chaotic state of the nomenclature and classification of these birds. Reconstruction of some species has been done, with the purpose of having an idea about the size, body weight, posture and habit based in their skeletons. The European species, Ameghinornis minor and Aenigmavis sapea are refuted as belonging to this family. Also several forms described from the Tertiary of Argentina are refuted, because they are based on inadequate segments of the skeleton for a good identification, as is the case of the genera Cunampaia, Smiliornis, Pseudolarus,... |

| This is the first study to detection the genetic relationship between Porphyrio alleni and four Rallidae species: Fulica atra, Gallinulla angulata, Gallinulla chloropus and Porphyrio porphyrio. Mitochondrial cytochrome oxidase subunit I (COI) sequences were used as an effective marker in this study. DNA of Rallidae species were extracted, amplified using polymerase chain reaction (PCR) and then sequenced. The results obtained from information based on COI sequences revealed that Gallinulla angulata and Gallinulla chloropus fall into two separate clades and they are not monophyletic. This suggests that, two moorhens could not be laid into the same genus. In addition, Porphyrio porphyrio was included in the same genus with Porphyrio alleni but they were... |
