Description[]

Paleoart by Kamilowjulian
Fluvionectes estimations conclude that the species, most likely, reached 5 metres (16 ft) long. Fluvionectes appears to have been a species that adapted to freshwater habitat, in contrast to most elasmosaurs species which were oceanic or sea based.[2]
Classification[]
The describers placed Fluvionectes in the Elasmosauridae family and Elasmosaurinae subfamily, in a clade with Albertonectes, Nakonanectes, Styxosaurus, and Terminonatator.
