late 1990s. The taxonomic status of this bonebed has fluctuated over time. It has been debated whether the material represents a singular species or a combination of two distinct ones; but today a single, variable species is considered most likely. It was suggested the material likely belong to Koutalisaurus, based on geographic proximity, but this reassignment was abandoned when that genus was recognized as indeterminate. Since then, it has instead been tentatively assigned to the genus Pararhabdodon. However, due to the lack of any suitable material for comparison and the lack of tsintaosaurin characteristics in the bonebed material, it has been more recently suggested that it should instead be considered indeterminate lambeosaur material. The 2020 hindlimb description allowed for distinction between Pararhabdodon and the Basturs Poble material to be solidified, with the bonebed material showing inconsistent femoral anatomy with the genus. Relationship with "Koutalisaurus" Near the village Abella de la Conca, in the 1990s, palaeontologist Marc Boada discovered a new site in the Talarn Formation, bearing dinosaur fossils. From this site, later named Les Llaus (LL), a right dentary, specimen designation IPS SRA 27, was excavated. In 1997, Casanovas-Cladellas and colleagues stated this dentary was discovered from SRA, the site where the original Pararhabdodon remains were found. The following year, they described the specimen and referred it to P. isonensis, and again stated it was from the same stratigraphic level. In 2006, the stratigraphy of the region was re-evaluated by Albert Prieto-Márquez and colleagues, and the dentary's location was corrected to the LL locality, away from and below the SRA locality. They noted that no dentary had been found at the SRA locality to compare to the LL specimen, and so they restricted P. isonensis to material known from its original locality. Additionally, they named a genus and species for IPS SRA 27, Koutalisaurus kohlerorum. One autapomorphy (unique trait) was used to diagnose the taxon as a new species: a very elongated edentulous section on the dentary, which was medially (inwardly) extended. The authors noted the possibility that future discoveries could lead to synonymization of their taxon with P. isonensis Evidence for this synonymy would later come in a 2009 study, from Prieto-Márquez alongside Jonathan R. Wagner. Material from Pararhabdodon, the holotype of Koutalisaurus, and material of the Chinese species Tsintaosaurus spinorhinus were examined and compared, and the edentulous slope previously thought unique to Koutalisaurus was found to be nearly
