In Depth

       Originally named as a species of Steneosaurus,‭ ‬S.‭ ‬obtusidens was renamed as a distinct genus in‭ ‬2017.‭ ‬The describers created the name Lemmysuchus which means‭ ‘‬Lemmy’s crocodile‭’‬.‭ ‬This was in honour of Ian Fraser Kilmister,‭ ‬the lead singer and founder of the band Mot�rhead,‭ ‬who everyone knew as Lemmy.

       Lemmysuchus was a thalattosuchian,‭ ‬more loosely known as sea crocodile,‭ ‬though not technically related to modern crocodiles.‭ ‬Further to this,‭ ‬Lemmysuchus was a teleosaurid,‭ ‬meaning that it would have retained some terrestrial features and‭ ‬still been able to comfortably move about on land as well as in the water.‭ ‬As such,‭ ‬Lemmysuchus probably roamed about coastal lagoons and coastlines hunting for whatever creatures it could catch.‭ ‬The stronger skull and jaws of Lemmysuchus compared to other teleosaurid genera,‭ ‬suggest that Lemmysuchus could more easily crunch through armoured prey such as turtles and crabs.‭ ‬Relative teleosaurid genera however are more gharial like with long slender jaws more suited to softer prey such as fish.‭
