In Depth

       Caieiria 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.‭ ‬allocaudata,‭ ‬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.
