Description:
Futalognkosaurus is a genus of titanosaurian dinosaur. The herbivorous Futalognkosaurus lived approximately 87 million years ago in the Portezuelo Formation of the Coniacian stage of the late Cretaceous Period. The fish and fossilized leaf debris on the site, together with other dinosaur remains, suggest a warm tropical climate in Patagonia during this period. The type species, Futalognkosaurus dukei, is estimated to be 26 m (85 ft) ~34 m (111 ft) in length, rivaling the gigantic Argentinosaurus. Its long neck contained 14 vertebrae, and was over a meter deep in places, due to its extremely tall neural spines which had a distinctive "shark-fin" shape. The hips were also extremely large and bulky, reaching a width of nearly 3 metres (9.8 ft). The alternate early spelling "Futalongkosaurus" may be found in some press reports and on websites.
Futalognkosaurus is in the top 10 largest described dinosaurs known to man
Discovery:
Its fossils were found in the Neuquén province of Argentina in 2000, and were scientifically described in 2007. The genus name is derived from the local indigenous language Mapudungun and is pronounced foo-ta-long-koh-sohr-us: "futa" means "giant" and "lognko" means "chief". It is based on three fossil specimens, yielding an estimated 70% of the skeleton in total with Partial skeletons and isolated material. The fossil team described the find as "the most complete giant dinosaur known so far".
what was found of Futalognkosaurus and several isolated material charted in, more of this dinosaur has been found than the famous Giganotosaurus
Classification:
In their phylogenetic analysis, Calvo and colleagues found Futalognkosaurus to be a member of the Titanosauridae (or Lithostrotia, depending on the definitions being used), and most closely related to Mendozasaurus. They defined a new clade for the group containing both Futalognkosaurus and Mendozasaurus, their common ancestor, and all descendants, which they named the Lognkosauria. The authors found Malawisaurus to be the sister group of this new clade. Another, much later member of Lognkosauria is the colossal Puertasaurus, which may be the biggest dinosaur so far known. Besides Futalognkosaurus, other fauna was discovered in the Futalognko site, including two further undescribed sauropod taxa, specimens of Megaraptor, Unenlagia and some pleurodiran turtles.

1. ANATOMY OF FUTALOGNKOSAURUS DUKEI CALVO, PORFIRI,GONZÁLEZ RIGA & KELLNER, 2007 (DINOSAURIA, TITANOSAURIDAE)FROM THE NEUQUÉN GROUP (LATE CRETACEOUS), PATAGONIA, ARGENTINA
ABSTRACT: "Titanosaurs are among the largest dinosaurs known to date. Here we describe the anatomy of
Futalognkosaurus dukei, the most complete giant sauropod ever found. It comes from outcrops of the Portezuelo
Formation at the Barreales lake, some 90 km northwest of Neuquén city (Patagonia). The specimen consists
of a complete neck, dorsal vertebrae with ribs, pelvis, and one caudal vertebra. Futalognkosaurus dukei is a
member of the Titanosauridae and belongs to the Lognkosauria, a clade that includes Mendozasaurus
neguyelap and probably also the giant Puertasaurus reuili."

2. A new Cretaceous terrestrial ecosystem from Gondwana with the description of a new sauropod dinosaur
Abstract: "A unique site at the northern area of Patagonia (Neuquén, Argentina) reveals a terrestrial ecosystem preserved in a
detail never reported before in a Late Cretaceous deposit. An extraordinary diversity and abundance of fossils was
found concentrated in a 0.5 m horizon in the same quarry, including a new titanosaur sauropod,Futalognkosaurus dukei
n.gen., n.sp, which is the most complete giant dinosaur known so far. Several plant leaves, showing a predominance of
angiosperms over gymnosperms that likely constituted the diet ofF. dukeiwere found too. Other dinosaurs (sauropods,
theropods, ornithopods), crocodylomorphs, pterosaurs, and fishes were also discovered, allowing a partial reconstruction
of this Gondwanan continental ecosystem."
