Lake Ammondosaurs

Ranging across the sub-arctic. Native to the innumerable unexplored glacial lakes of Alaska, Canada, the Pacific Northwest, and Great Lakes Region. Also found across the Russian Far East, Siberia. The Lake Ammondosaurs (Boreoammondosaurinae; Boreoammondosaurus palustris species Complex) are a species complex of Freshwater Ammondosaurid Thyreophorans containing a staggering 2,700 species.

Biology

Species in this complex average out at 4-6 feet in length.

As with all Ammondosaurs this species complex, lacks a syrinx. They communicate through low-pitched infrasonic calls as well as very loud, belch like vocalizations. Additionally, several species are capable of echolocation and communicate with a highly complex series of sounds, which some scientists think could be language.

Ecology

Each species of Lake Ammondosaur 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 Ammondosaurs are often the apex predator of their water body, though they usually share this position alongside members of the other Glacial Lake species Complexes such as Lake Zeuglodonts, Lake Dragons, Lake Ichthyosaurs, Lake Mosasaurs, Lake Serpents, Lake Plesiosaurs, Lake Pliosaurs, Variable Lake Monsters. Some smaller species are known to be preyed upon by Northern Pike, Muskellunge and Raptors such as Bald Eagles and Osprey. Ammondosaurs are also often eaten by Humans, especially by Ojibwe, Chippewa and Algonquin peoples. Their taste is very similar to Alligator.
