Teratornithidae is an extinct family of very large birds of prey that lived in North and South America from the Late Oligocene to Late Pleistocene. They include some of the largest known flying birds. Its members are known as teratorns.
[12] [13] For comparison, the living bird with the largest wingspan is the wandering albatross, averaging 3 m (9 ft 10 in) and spanning up to 3.7 m (12 ft 2 in). When grounded, Argentavis' height has been estimated at 1.5 to 1.8 m (4 ft 11 in to 5 ft 11 in), roughly equivalent to that of an adult human.
This height was recorded over Nevada; [1] [4] [5] This record occurred when a Lockheed L-188 Electra turboprop airliner operating a Western Airlines flight suffered a bird strike at cruising altitude. [8] Bar-tailed godwit: Limosa lapponica: Scolopacidae: 6,000 metres (20,000 feet) [5] [9] It can reach this height while migrating. White stork ...
The largest of non-pterodactyloid pterosaurs as well as the largest Jurassic pterosaur [16] was Dearc, with an estimated wingspan between 2.2 m (7 ft 3 in) and 3.8 m (12 ft). [17] Only a fragmentary rhamphorhynchid specimen from Germany could be larger (184 % the size of the biggest Rhamphorhynchus ). [ 18 ]
The largest bird in the fossil record may be the extinct elephant birds (Vorombe/Aepyornis) of Madagascar, which were related to the ostrich. They exceeded 3 m (9.8 ft) in height and 500 kg (1,100 lb) in weight. [44] The last of the elephant birds became extinct approximately 1000 years ago.
Diurnality, plant or animal behavior characterized by activity during the day and sleeping at night. Cathemeral, a classification of organisms with sporadic and random intervals of activity during the day or night. Matutinal, a classification of organisms that are only or primarily active in the pre-dawn hours or early night.
Analyzing a leg bone from a fossil site in Colombia, scientists have identified a massive “terror bird” that lived about 12 million years ago.
Late Quaternary prehistoric birds are avian taxa that became extinct during the Late Quaternary – the Late Pleistocene or Early Holocene – and before recorded history, specifically before they could be studied alive by ornithological science. They had died out before the period of global scientific exploration that started in the late 15th ...
