In Depth

       Rileyasuchus was originally‭ ‬named as Rileyia,‭ ‬but was changed to Rileyasuchus when it was realised that Rileyia had been used to name a genus of hymenopteran insect.‭ ‬Aside from this Rileyasuchus has had a problematic taxonomic history with speculation that fossils of the dinosaur Thecodontosaurus may be mixed in with it.‭ ‬In addition to this the known fossils of Rileyasuchus are so undiagnostic that it would be very difficult to attribute further remains to the genus with certainty.
