       Fossils of Abditosaurus were originally discovered in‭ ‬1954‭ ‬and then described in‭ ‬1956‭ ‬as belonging to Hypselosaurus.‭ ‬Further study 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.
