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.
