paleontologist Franz Nopcsa in 1928 from Vălioara, Romania. Nopcsa found bone fragments in a deposit of the Hațeg Basin that dates back to the late Maastrichtian stage – the very end of the Late Cretaceous. Several partial skulls from Spain and France were attributed to A. precedens in 2001. Some of these skulls came from Campanian-age deposits slightly older than those in Romania, meaning that the species must have persisted for about 5 million years. A 2013 study proposed that the French and Spanish fossils assigned to A. precedens in 2001 might actually represent a new unnamed species of Allodaposuchus currently identified as Allodaposuchus sp. A study published in 2005 had suggested that these fossils belong to several different genera of crocodylomorphs and that the original Romanian material is too fragmentary to assign to its own genus, making Allodaposuchus a nomen dubium or "dubious name". However, the 2013 study reaffirmed the Romanian material's distinctiveness from other European Cretaceous crocodylomorphs and therefore reaffirmed the validity of Allodaposuchus as a genus. Allodaposuchus (Agaresuchus) subjuniperus ? In 2013, a second species of Allodaposuchus, A. subjuniperus, was named on the basis of a skull from the late-Maastrichtian Conquès Formation, part of the Tremp Group, in the province of Huesca, Spain. The skull was found underneath a juniper tree whose roots had grown between the bones, hence the species name subjuniperus or "under juniper" in Latin. However, in 2016, A. subjuniperus was moved to a new genus, Agaresuchus along with the type species of that genus, A. fontisensis, on the grounds that the Spanish species were sufficiently distinct from A. precedens. In 2021, a phylogenetic analysis by Blanco disputed this result, suggesting that both A. fontisensis and A. subjuniperus belong within the genus Allodaposuchus proper, alongside the two species of Lohuecosuchus: L. megadontos and L. mechinorum. Allodaposuchus palustris In 2014, A. palustris was described from a partial skull and other skeletal fragments found in Maastrichtian age sediments of the Tremp Formation in a fossil locality called Fumanya Sud in the southern Pyrenees. These remains allowed for the first detailed description of the postcranial (non-skull) anatomy of Allodaposuchus. Allodaposuchus hulki A fourth species of Allodaposuchus, A. hulki, was named in 2015 and also came from the Tremp Formation, although this time in a locality called Casa Fabà. The species is named after the Hulk from Marvel Comics, in reference to features on the bones that suggest
