Dynatoaetus is an extinct genus of large bird of prey from the Pleistocene of Australia.It is among the largest known raptors of the region, second only to the Haast's eagle of New Zealand, with estimates suggesting a weight of up to 12 kg (26 lb).
Eggs laid by the ostrich are the largest in the world, weighing 1.4 kg (3.1 lb). The emu (Dromaius novaehollandiae) of Australia reaches 1 to 1.3 m (3.3–4.3 ft) at the shoulder with a full height of 150 to 190 cm (59–75 in). In length measured from the bill to the tail, emus range from 139 to 164 cm (55 to 65 in).
The visual acuity of some large raptors such as eagles and Old World vultures are the highest known among vertebrates; the wedge-tailed eagle has twice the visual acuity of a typical human and six times that of the common ostrich, the vertebrate with the largest eyes. [41]
The fossil remains of this raptor, scientifically known as Murusraptor barrosaensis, were discovered in 2000. It took University of Alberta paleontologist Philip Currie and his team until recently ...
Steller's sea eagle is the largest bird in the genus Haliaeetus and is one of the largest raptors overall. Females vary in weight from 6.2 to 9.5 kg (14 to 21 lb), while males are rather lighter with a weight range of 4.9 to 6.8 kg (11 to 15 lb).
The 5-ton apex-predator measuring 3 stories from nose to tail was found eviscerated its prey with sharp, curved claws.
The largest known New World monkey was Cartelles, which is studied as specimen of Protopithecus, weighing up to 34.27 kg (75.6 lb). Caipora bambuiorum is another large species, weighing up to 27.74 kg (61.2 lb). [226] The largest omomyids were Macrotarsius and Ourayia from the Middle Eocene. Both reached 1.5–2 kg (3.3–4.4 lb) in weight. [227]
The skull features of teratorns still share a lot of crucial similarities with specialized scavenging raptors. Many old world vultures possess large bills similar to teratorns, and a longer bill is in fact an anatomic feature that points toward a scavenging rather than a predatory life style, as this allow them to probe deeper into large ...
