is a genus of titanosaur that lived in South America during the late
Cretaceous. At the time of its naming, Caieiria
was only known from
tail vertebrae. These vertebrae however show strongly developed side
process as well as vertical spines about half the height of the centra
(the round disc part of the vertebrae). The anterior caudal
vertebrae also show a developed excavation. It is a combination of
these features which led to the type species name of C.
the allocaudata part basically meaning ‘strange tail’.
Like other Titanosaurs, Caieiria is expected to have had the long the neck and tail of other similar dinosaurs of its kind, as like relatives, possibly armoured osteoderm plates within the skin of its body, though at the time of writing that is just conjecture for this dinosaur.
