Argentavis may have used its wings and size to intimidate metatherian mammals and small phorusrhacids to take over their kills. [ 8 ] [ 19 ] Phorusrhacids were the largest land predators in Miocene South America, and probably the biggest threats that Argentavis faced, with the largest species that coexisted with Argentavis , Devincenzia ...
This is a list of large extant primate species (excluding humans) that can be ordered by average weight or height range.There is no fixed definition of a large primate, it is typically assessed empirically. [1]
Pelagornis sandersi comparison with the Andean condor (Vultur gryphus) and the wandering albatross (Diomeda exulans). The sole specimen of P. sandersi has a wingspan estimated between approximately 6.06 and 7.38 m (19.9 and 24.2 ft), [9] giving it the largest wingspan of any flying bird yet discovered, twice that of the wandering albatross, which has the largest wingspan of any extant bird (up ...
They range in size variably, but on average measure 53–64 cm (21–25 in) in length, have a wingspan of 103–117 cm (3.38–3.84 ft) and weigh 0.63–1.4 kg (1.4–3.1 lb). [56] The Henst's goshawk ( Accipiter henstii ) and Meyer's goshawk ( Accipiter meyerianus ) do rival it in terms of wing size and body mass.
Size comparison between a human and two species of Basilosaurus, B. cetiodes (dark blue) and B. isis The heaviest archeocete , and possibly the heaviest known mammal was Perucetus , with weight estimated at 85–340 t (84–335 long tons; 94–375 short tons), while length is estimated at 17.0–20.1 meters (55.8–65.9 ft), [ 107 ] possibly ...
Size of Paraceratherium (dark grey) compared to a human and other rhinos (though one study suggests Palaeoloxodon namadicus may have been a larger land mammal). The blue whale is the largest mammal of all time, with the longest known specimen being 33 m (108.3 ft) long and the heaviest weighted specimen being 190 tonnes.
A millimeter-sized sea animal could hold clues to the evolution of the human nervous system. While placozoans are simple animals only as big as a grain of sand, the blobs have unique cells that ...
It is known from a humerus, parts of the cranium, beak, sternum, and vertebrae which indicate an estimated wingspan of over 4 metres (13 ft). The find dates to the Late Pleistocene, between 11,000 and 12,000 years ago, in a stratum which is filled with the bones of mastodons, sloths, and condors, and has evidence of human habitation.
