借BioOne里说下窃鹤kelenken
The anatomy of a new, enormous phorusrhacid (Aves: Cariamae) from the Middle Miocene Collón Curá Formation of northwestern Patagonia (Río Negro province, Argentina) is described. The new phorusrhacid is known by a single specimen that consists of a nearly complete skull associated with a tarsometatarsus and a pedal phalanx. The new fossil is the largest known phorusrhacid and its morphology resembles more that of taxa traditionally grouped within phorusrhacines. Its skull—by far the best preserved among large phorusrhacids—provides a great deal of previously unknown anatomical information and indicates that reconstructions of the skull of gigantic phorusrhacids based on their smaller relatives are unwarranted.

million years ago. The fossil record for this group of birds is almost exclusively
South American, where they have been recovered fromthe late Oligocene
to Pliocene deposits in predominantly Argentina and Uruguay [Baskin 1995].
Phorusarchids arrived in North America subsequent to the Panamanian land
bridge connection between North and South America, which occurred approximately
2.3 million years ago.
Since the first discovery in Patagonia by the Chicago Field Museum paleontologist
in the 1890s, paleontologists have believed that these flightless predatory
birds evolved on the island continent of South America as the dominant
carnivores on land. Their closest relatives are an extant group of volant birds,
Cariamas, that live in Argentina and Brazil [Riggs 1939]. Recent discoveries of
phorusrachid fossil material in older sediments (Eocene-Oligocene) in Europe
challenge the notion that these birds were exclusively from South America,
suggesting that they evolved from an earlier group of birds that diversified on
the continent of Gondwana [Mourer-Chauvirz 1981].
Phorusrachids ranged in size from 5 feet to 9 feet tall [Marshall 1994], with
Titanis being the largest of these birds known. Because very little material of
Titanis has been discovered, its exact size in unclear; estimates range from 6 to
7 ft tall [Brodkorp 1963; Chandler 1994; Marshall 1994]. Recovered material
from Northern Florida includes two quadratojugal bones (cheek bones), two
cervical vertebrae, a thoracis vertebra, two hands, and portions of foot bones
[Brodkaup 1963; Chandler 1994]. From Texas, only a single element from a toe
bone is known [Baskin 1995].

讨论的好精彩……
kelenken最大应该是280kg。百度百科这种垃圾就别看了……
kelenken比泰坦高了三分之一,kelenken是在200-250kg之间?
最大的不清楚,我发的这个应该是200左右,好像才180kg
kelenken体重应该是比泰坦大30kg……
