Fluvionectes (meaning "river swimmer", from both Latin and Greek) is a genus of elasmosaurid plesiosaur found in the Dinosaur Park Formation in Alberta, Canada . It is known from a holotype, which includes parts of the trunk area, and from a much larger specimen referred to this taxon.[1]

Description

The holotype indiviudal of Fluvionectes reached 5 m (16 ft) long. A much larger specimen indicates that this taxon may have reached 7 m (23 ft) in maximum body length.[1]

Classification

The describers placed Fluvionectes in the Elasmosauridae, in a clade with Albertonectes, Nakonanectes, Styxosaurus, and Terminonatator, which by definition places it in the Elasmosaurinae subfamily.[1]

Paleobiology

Fluvionectes appears to have been a freshwater (and possibly brackish water) animal based on its discovery from a non-marine to paralic sedimentary unit. This is significantly different in contrast to most elasmosaurs which were oceanic.[1]
