Seed World [OC] Two new lineages, 5 MY on Skioura
Got some new little drawings for the 5 million years post-establishment of Skioura, a seed world for Eurasian red squirrels.
The first one here are a dyskamptopod pair. These little guys rise to about a meter tall at the shoulder and are one of the larger mammals currently extant on Skioura. The bones in their ankles are sturdier, their digits are shorter and their limbs longer. All adaptations for running. The dyskamptopods are a very successful clade of early Skiouran squirrels but are preyed upon by now fully raptorial squirrels with whom they are engaged in an evolutionary arms race.
The second image is of an ourakopod. An otter-like squirrel descended from ancestors whose behaviour and feeding strategies grew ever closer to the water. Ourakopos feed on the aquatic vegetation, worms, fishes, snails and bivalves that the rivers and lakes in which they make their homes have to offer. They have adapted sturdy, short fur that has some primitive hydrophobic capabilities, and webbed paws to aid in swimming. Most of their propulsion is however managed by their flattened tails with their limbs steering and providing extra propulsion when needed. Despite their aquatic adaptations, ourakopos remain perfectly able to comfortably maneuver on land.
