of Abditosaurus were originally discovered in
1954 and then
described in 1956 as belonging to Hypselosaurus.
later in the twentieth century however began to see the Hypselosaurus
genus as a dubious one, and many fossils that were assigned to new
genera. A fresh expedition to the 1954 discovery site between
2012 and 2014 discovered additional fossil remains that were
then described in 2017. In 2022 a new genus, Abditosaurus,
was erected to include these fossils.
Abditosaurus is a genus of titanosaurian dinosaur that lived in Western Europe during the late Cretaceous. More specifically Abditosaurus is a saltasaurine titanosaur. One key discovery about Abditosaurus is that the neck and back vertebrae were found partially articulated, a rare discovery in sauropods/titanosaurs. The estimated size of the Abditosaurus holotype has revealed this dinosaur to have been quite large when compared to other European titanosaur genera (e.g. Magyarosaurus) living in the Late Cretaceous.
