About
The top ground-shakers during the
Late Cretaceous, Lognkosauria is a group of giant long-necked sauropod dinosaurs within the clade Titanosauria, that includes some of the largest and heaviest dinosaurs to ever walk the earth.
Lognkosaurs (members of Lognkosauria) were "chunky" with an extremely wide rib cage, and super wide neck and back vertebrae thanks to very robust cervical ribs and massive neural spines on the former and wing-like side processes on the latter.

Etymology
Lognkosauria is derived from the Mapuche "Lognko" (chief), and the Greek "saurus" (lizard) and "-ia" (neuter plural).
