In Depth

       Described from a single partially preserved skull,‭ ‬Alexandronectes was an elasmosaurid plesiosaur that swam in the waters around what is now New Zealand during the late Cretaceous.‭ ‬These were dangerous waters as fossils of large mosasaurs such as Taniwhasaurus are also known from the same formation as Alexandronectes,‭ ‬and these predators were certainly capable of hunting and killing plesiosaurs.
