Lake Plesiosaurs
Ranging across the sub-arctic. Native to the innumerable unexplored glacial lakes of Alaska, Canada, the Pacific Northwest, and Great Lakes Region. The Lake Plesiosaurs (Stagnisauropterygidae; Stagnilasmosaurus borealis species Complex and Stagnipleurodon boralis Species Complex) are a pair of species complex of Freshwater Plesiosaurs and Pliosaurs containing a staggering 3,000+ species.
Biology
Species in this complex average out at 4 feet in length.
Ecology
Each species of Lake Plesiosaur is native to one or two Freshwater Lakes that began to form at the end of the Last Glacial Period around 14,000 years ago, as retreating ice sheets exposed the basins they had carved into the land, which then filled with meltwater. A series of meltwater floods allowed a handful of or a single species of ancestral lake whale to migrate to hundreds of lakes, where they were then isolated and began to evolve into new species.
Lake Plesiosaurs in the Plesiosaurine Group are often mid-level shallow-water and open-water predators of their water body, Feeding on fish, crustaceans, mollusks.
Lake Plesiosaurs in the Pliosaurine Group are top-level predators, Feeding on Fish, Crustaceans, mollusks, turtles, Lake Ammondosaurs, Lake Dragons, Lake Ichthyosaurs, Lake Mosasaurs, Lake Zeuglodonts, and Lake Serpents. not many creatures prey on them once they reach adulthood, their only frequent predators being raptors and the occasional Mosasaur.
