About: Spec Dinosauria: Avisauridae   Sponge Permalink

An Entity of Type : owl:Thing, within Data Space : 134.155.108.49:8890 associated with source dataset(s)

Home-Earth has an impressive diversity of terrestrial carnivorous flying birds: owls, falcons, hawks, buzzards, eagles, ospreys, and so on. All these predators, with the exception of a few megalomaniac songbirds (Passeriformes), kingfishers (Alcedinidae) and frogmouths (Podargidae), belong to the Falconiformes (diurnal birds of prey) and the Strigiformes (owls), two groups of Neornithes that arose in the Eocene or perhaps Palaeocene. Spec's birds of prey, the avisaurs, are somewhat different.

abstract
  • Home-Earth has an impressive diversity of terrestrial carnivorous flying birds: owls, falcons, hawks, buzzards, eagles, ospreys, and so on. All these predators, with the exception of a few megalomaniac songbirds (Passeriformes), kingfishers (Alcedinidae) and frogmouths (Podargidae), belong to the Falconiformes (diurnal birds of prey) and the Strigiformes (owls), two groups of Neornithes that arose in the Eocene or perhaps Palaeocene. Spec's birds of prey, the avisaurs, are somewhat different. Most immediately noticeable, avisaurs possess of teeth and lack a beak (hooked or otherwise), which gives their heads a surreal dromaeosaur-like appearance. Also, despite many neornithine-like features in their flight apparatus, they belong to the Enantiornithes, that strange group of 'opposite-birds' that arose in the Early Cretaceous with forms like Cuspirostrisornis.
