Tusk Grazers continue to find success in the Ice Box Age where Cephalopes become faster and better at running Tusk Grazers survive by simply being massive and being less picky in their diet than their contemporaries.
With large crushing beaks that can crush plant matter, meat, and bones alike, 9 feet tall and 4 to 6 tones Brute Grazers are the largest living Tera Squid and the second largest ever only behind the Mega Squid. These animals can now effectively compete with the more specialized herbivores by simply bulldozing their way over everything else with highly aggressive temperaments to secure the best food often at the exclusion of competitors furthermore, Brute Grazers themselves are social animals living in large herds that stripe grass from across the landscape. Well, their feeding method is less efficient than Cephalopes that have sharp-beak pectin to grind plants between the top and bottom Brute Grazer's large size lets them bite threw anything they eat putting further evolutionary pressure for large sizes as larger Brute Grazers can eat more plant matter faster.
The large size of this group has evolved extremely quickly meaning most predators won't even touch them as herds of Tusk Grazers plod the land in search of food. Combined with their ornery nature and propensity to inflate the skin around their tusks which connects to their sinuses and nostrils behind their eyes with there long tusk mean few animals dear to hunt them to the point that there among the most common megafauna on the grassland.
Brute Grazers have a tremendous impact on the grasslands their trampling of the terrain often causes cave-ins letting larger animals like Jutter Jaws move into burrows displacing other burrowing Squid Rodents and Dodirts. This trampling of grass also stomps out the growth of taller sedge brush and the Absorbent Suckers Lichen Tree host resulting in successful seedlings surviving closer to the parent trees and encouraging other larger plants to grow closer to the Lichen Trees creating stands of Lichen Tree forest in places normally to dry to support tree's
Brute Grazers and their genus (the Dinoteuthids) along with there more ghoulish relatives are here to stay in the ice age although in time predators big enough to hunt them will evolve slowing there meteoric rise.
Meanwhile, Cephalopes will learn to deal with their new giant neighbors. Some survive by getting faster others will get smaller well others will take on bizarre new appearances to gain a competitive edge.
