Fossil representation: Teeth.

       Euronychodon is a tooth taxon which means that so far the only known fossils of this dinosaur are teeth.‭ ‬Study of these teeth suggests that they most probably belong to a troodont dinosaur but beyond this further details are impossible to establish.‭ ‬There have been questions raised about the validity of the Euronychodon fossil from Uzbekistan.‭ ‬This is because the fossils from here are estimated to come from the Turonian stage of the late Cretaceous,‭ ‬while the European‭ (‬and holotype‭) ‬fossils are almost certainly all Maastrichtian in age.‭ ‬Therefore it is not impossible that the teeth fossils attributed to Euronychodon from Uzbekistan may actually be from a different dinosaur genus.
