The owl's remains date back to the Miocene-Pliocene boundary 5.5 to 5 million years ago. The fossil bones are about 60% as long again as a modern barn owl, [1] giving a total length of about 50–65 cm for T. robusta. This owl provides an interesting case study of evolution and insular gigantism.
The bird family Tytonidae, which includes the barn owls Tyto and the bay owls Phodilus, is one of the two families of owls, the other being the true owls or typical owls, Strigidae. They are medium to large owls with large heads and characteristic heart-shaped faces. They have long, strong legs with powerful talons. They also differ from the ...
Paleodictyon consist of thin tunnels or ridges that usually form hexagonal or polygonal-shaped honeycomb-like network. [1] Both irregular and regular nets are known throughout the stratigraphic range of Paleodictyon, but it is the striking regular honeycomb pattern of some forms such as P. carpathecum and P. nodosum which make it notable and widely studied.
They are called spectacled owls because of their prominent facial pattern. The genus contains the following species: The genus contains the following species: Genus Pulsatrix – Kaup , 1848 – three species
The fossil owls "Otus" wintershofensis and "Strix" brevis, both from the Early or Middle Miocene of Wintershof, Germany, are close to this genus; the latter was sometimes explicitly placed in Ninox (Olson 1985), but is now in Intutula. "Strix" edwardsi from the Late Miocene of La Grive St. Alban, France, might also belong into this group.
The American (North and South America) horned owls and the Old World eagle-owls make up the genus Bubo, at least as traditionally described. The genus name Bubo is Latin for owl . Its name in Russian филин ( Russian for 'filin') is one of the few native Russian words containing the letter Ф .
The trackway Protichnites from the Cambrian, Blackberry Hill, central Wisconsin. A trace fossil, also known as an ichnofossil (/ ˈ ɪ k n oʊ f ɒ s ɪ l /; from Greek: ἴχνος ikhnos "trace, track"), is a fossil record of biological activity by lifeforms but not the preserved remains of the organism itself.

The giant Cuban owl or giant cursorial owl (Ornimegalonyx) is an extinct genus of giant owl that measured 1.1 metres (3 ft 7 in) in height. It is closely related to the many species of living owls of the genus Strix. [1] It was a flightless or nearly flightless bird and it is believed to be the largest owl that ever existed.
