In Depth

       Chenanisaurus is a genus of abelisaurid dinosaur that lived in North Africa towards the end of the Cretaceous period.‭ ‬Chenanisaurus is named from‭ ‬the description of a partial lower jaw,‭ ‬and while this does not give us much to go on,‭ ‬it does reveal a few things.‭ ‬While the jaw is incomplete,‭ ‬it is that of an abelisaurid dinosaur,‭ ‬and comparable in size to other large abelisaurid dinosaurs.‭ ‬This jaw alone suggests that Chenanisaurus grew to at least seven meters long,‭ ‬maybe more,‭ ‬though precise details cannot be certain front the jaw alone.‭ ‬The jaw is also proportionately high to what its complete length would have been,‭ ‬showing adaptation for a very high bite force.‭ ‬The holotype bone of Chenanisaurus was found in marine sediment,‭ ‬showing that this individual had been swept out to sea.
