Species: M.‭ ‬brevis‭ (‬type‭)‬.
Diet: Carnivore/Piscivore.
Size: From‭ ‬2.5‭ ‬to as much as‭ ‬5.5‭ ‬meters long.

Fossil representation: Remains of at least one individual.

       Exact measurements of Miodentosaurus have been hard to establish,‭ ‬but this could be the largest thalattosaur genus there is.‭ ‬At the time of writing the next largest genus is Concavispina,‭ ‬which is confirmed to have at least grown to as big as‭ ‬3.64‭ ‬meters long.‭ ‬Like its smaller cousins,‭ ‬Miodentosaurus was a reptile that still possessed its legs that were developed enough for scrambling about on land,‭ ‬but it seems to have hunted in the sea for food.‭ ‬The tail of Miodentosaurus is laterally compressed so that it could be undulated in a side to side movement similar to how you can see a crocodile swim today.‭ ‬Despite its large size,‭ ‬Miodentosaurus probably hunted for smaller prey such as fish.
