       When first described in‭ ‬1982‭ ‬Dianchungosaurus was thought to represent a small Jurassic dinosaur,‭ ‬and until the early years of the twenty-first century was listed as a heterodontosaurid dinosaur.‭ ‬In‭ ‬2005‭ ‬however a study by Barret and Xu discovered that the original description of Dianchungosaurus was actually based upon a fossil chimera,‭ ‬described from the remains of two different types of animal.‭ ‬These original fossils are now known to have come from a crocodylomorph and sauropodomorph dinosaur.‭ ‬Because the actual holotype fossil‭ (‬IVPP V4735a‭) ‬was from the crocodylomorph,‭ ‬Dianchungosaurus is now listed as a crocodylomorph,‭ ‬not a dinosaur.
