Name: Mochlodon ‭(‬Bar tooth‭)‬.
Phonetic: Mock-loe-don.
Named By: Harry Govier Seeley‭ ‬-‭ ‬1881.
Synonyms: Iguanodon suessi.
Classification: Chordata,‭ ‬Reptilia,‭ ‬Dinosauria,‭ ‬Ornithischia,‭ ‬Ornithopoda,‭ Iguanodontia,‭ ‬Rhabdodontidae.
Species: M.‭ ‬suessi‭ (‬type‭)‬.

Time period: Campanian of the Cretaceous.
Fossil representation: Dentary‭ (‬part of the lower jaw‭) ‬and partial post cranial remains.

       The original bones of Mochlodon were first discovered in‭ ‬1859,‭ ‬but were not formerly identified until‭ ‬1870.‭ ‬When named by Emanuel Bunzel,‭ ‬the remains were identified as those of a new species of Iguanodon.‭ ‬However,‭ ‬by this time Iguanodon was being treated as a‭ '‬wastebasket taxon‭' ‬for any remains that had a superficial similarity to the now world famous Iguanodon.‭ ‬Harry Govier Seeley declared the remains as being worthy of their own genus,‭ ‬creating the name Mochlodon after a pronounced ridge that runs down the middle of each tooth.
       Mochlodon has a strong similarity to another European dinosaur named Rhabdodon,‭ ‬so much so that many species once assigned to Mochlodon have been transferred to Rhabdodon because closer study has revealed them to actually belong to this genus.‭ ‬One of these species Mochlodon robustum that got changed to Rhabdodon robustum and then R.‭ ‬robustus has now been renamed into its own genus,‭ ‬Zalmoxes.‭ ‬However further studies of Zalmoxes and Mochlodon has led to some palaeontologists claiming that there are no clearly defined differences between the two,‭ ‬and may in fact be the same.‭ ‬Further fossil material may yet clear this and no changes are likely until absolute proof can be found to suggest that they are.‭ ‬If proven the same however,‭ ‬then Zalmoxes would be absorbed into Mochlodon because Mochlodon was named first.
