The long-awaited fifth version of my Futalognkosaurus dukei
skeletal. Everything has been revamped, from the swept-back dorsal neural spines and the more natural rib cage shape to the "shark-fin" neck processes, which are finally the correct height. Also the torso has been shortened slightly and the tail lengthened, and the head silhouette has a more prominent nasal arch. Finally I added a front view of one of the anterior dorsal vertebrae. Everything looks smoother, cleaner, and better-proportioned now - it's beginning to look a lot more like a finished product.Futalognkosaurus dukei
(Calvo et. al. 2007)
Taxonomy: Saurischia; Sauropodomorpha; Sauropoda; Macronaria; Titanosauria; Lognkosauria
Meaning of name: "Great Chief Lizard of Duke Energy Company"
Time: Late Cretaceous (Turonian-Coniacian epochs, ~ 90-87 million years ago)
Hailing from Late Cretaceous Argentina, Futalognkosaurus dukei
was one of the most massive dinosaurs ever known, with the deepest neck on record and a colossal pelvis exceeding 2m at its widest point. It's also the most complete giant titanosaur known, though due to the current lack of reliable measurements it's hard to tell just how "giant" the entire animal was. My skeletal reconstruction is done based on extensive cross-scaling using the best known unpublished photos [link]
and verifying the most reliable of the published measurements with the sizes of the people said photos.
Futalognkosaurus was a member of the family Lognkosauria, a transitional group of titanosaurs with a plethora of strange and extreme skeletal features, including extremely wide dorsal vertebrae and rib cages. They ranged from the small (Malawisaurus
) to the colossal (Puertasaurus
, a Late Cretaceous lognkosaur, was one of the larger members of the family, and so far the one with the tallest neck bones - indeed it may have proportionally the deepest neck of any sauropod with the exception of Isisaurus
Currently this recon shows Futalognkosaurus
at 100 ft. (30m), rivaling Argentinosaurus
in length, and likely exceeding both Paralititan
. Nevertheless the width of the vertebrae, though impressive, indicates it is still significantly smaller than both Puertasaurus
and the new adult Alamosaurus
remains, and it may also be outclassed by Ruyangosaurus giganteus
and Huanghetitan ruyangensis
. Never heard of these creatures? Sometimes I'm shocked at the sheer number of these record-breakers myself. We've truly come a long way since "Ultrasauros".
