In Depth

       Fabrosaurus has been widely considered to be a dubious genus due to the very incomplete nature of the type remains,‭ ‬a partial jaw and three teeth.‭ ‬The better known genus Lesothosaurus however has been speculated to be a synonym to Fabrosaurus,‭ ‬though the lack of remains for Fabrosaurus mean that such an observation remains only speculative.‭ ‬The lack of type remains for Fabrosaurus also mean that it would be very difficult to add new material to the genus unless a direct link to the holotype remains could be established‭ (‬i.e.‭ ‬further remains of the same individual with ideally a second individual supporting the find‭)‬.
