TL;DR: ChiapPE et al. as discussed by the authors discuss the relationship between birds and other theropod Dinosaurs and discuss the importance of birds in the development of modern birds and their relationships with other Dinosaurs.

TL;DR: These specimens are the first known pre-Holocene birds from Madagascar and the first avian skeletal remains from the Mesozoic era of a large portion of Gondwana.
Abstract: WE report the discovery of two exquisitely preserved specimens of a new, very primitive bird from the Late Cretaceous period of Madagascar. The new taxon, Vorona berivotrensis, is provisionally placed phylogenetically in an unresolved trichotomy with Enantiornithes and a clade consisting of Patagopteryx and Ornithurae. These specimens are the first known pre-Holocene birds from Madagascar and the first avian skeletal remains from the Mesozoic era of a large portion of Gondwana.

TL;DR: Bird fossils recovered from the Maevarano Formation document one of the most size- and phylogenetically diverse Cretaceous-age Gondwanan avifaunas, including representative basal pygostylian, enantiornithine, nonenantiornithsine, ornithothoracine, and (4) ornithurine taxa.
Abstract: Recent field efforts in the Mahajanga Basin of northwestern Madagascar have recovered a diverse Late Cretaceous terrestrial and freshwater vertebrate fauna, including a growing diversity of avialans. Previous work on associated bird skeletons resulted in the description of two named avialans (Rahonavis, Vorona). Other materials, including two synsacra and numerous appendicular elements, represent at least five additional taxa of basal (non-neornithine) birds. Among the materials described herein are two humeri tentatively referred to Rahonavis and numerous elements (e.g., humeri, ulnae, tibiotarsi, tarsometatarsi) assigned to Vorona. A near-complete carpometacarpus exhibits a minor metacarpal that exceeds the major metacarpal in length, documenting an enantiornithine in the fauna. Moreover, two additional, small humeri, an ulna, a femur, and a tarsometatarsus also compare favorably with enantiornithines. Finally, two other isolated humeri and a synsacrum are referable to Ornithurae. The latter sp...
