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.
Ogygoptynx is an extinct genus of owl from the Paleocene. [1] Dated to the Late Paleocene, this is the earliest known owl fossil, with a single species assigned to the taxon: Ogygoptynx wetmorei . [ 2 ]
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 ...
Protostrigidae is a prehistoric family of owls which occurred in North America, Europe, [1] and Asia [2] during the Eocene and early Oligocene periods. [1] Genera include Eostrix, Minerva, Oligostrix, [1] and Primoptynx. [3] In 1983, Cécile Mourer-Chauviré demonstrated that Protostrix is a junior synonym of Minerva. [1]

These owls date from the early Eocene of the United States, Europe, and Mongolia. They have been described based on fossil remains. They have been described based on fossil remains. The genus was created by Pierce Brodkorb in 1971 to place a fossil species known until that time as Protostrix mimica .
A number of owl fossils were at one time assigned to the present genus, but are nowadays placed elsewhere. While there are clear differences in osteology between typical owls and barn owls, there has been parallel evolution to some degree and thus isolated fossil bones cannot necessarily be assigned to either family without thorough study.
Scientists have found the U.K.’s largest dinosaur footprint site ever. The tracks were discovered in a quarry in Oxfordshire — about 60 miles northwest of London — by quarry employee Gary ...
