Lusonectes
was named from a combination of Luso (Portugese), and nectes
(swimmer), and at the time of its naming it was the only
plesiosaur genus named from a Portugese deposit. However Europe
during the Jurassic was more a collection of islands rather than the
single large land mass it is today, so it may only be a matter of
time before other Portugese plesiosaurs are discovered. The species
name L. sauvagei is in honour of the French
palaeontologist Henri
�mile Sauvage who found the first remains way back in the nineteenth
century.
Lusonectes
is thought to be most closely related to plesiosaurs like
Microcleidus,
and as such may represent a primitive form of
elasmosaurid plesiosaur. These are the sub group proportionately
longer necked plesiosaurs typified by Elasmosaurus.
