Perceived rodent analogues

Among small endothermic animals, a rodent like bodyplan has appeared many times throughout history. Think about mammals like rodents, hyraxes, lagomorphs, multituberculates, diprotodonts but also synapsids like dicynodonts and many more that have evolved to be small, mostly herbivorous critters, often with equipped with large incisors or beaks designed for cutting.
It should therefore come as no surprise that a similar phenomenon of convergent evolution can be seen on Eryobis. So far we have recorded seven groups of rodent analogues on Eryobis that all evolved independently. Among the Arachnotheres there are three, and among the Anisospondyls there are at least four.

The creatures depicted here are all generalised forms of with characteristics most often seen in members of their clades.

Top row, left: All members of this group of Arachnotheres, named Kentrotaria, appear to have feet split in the middle tipped with a number of smaller claws. Their tails are usually fairly long and their ears are tipped with venomous spurs that can break off and regrow.

Top row, middle: Not quite Arachnotheres, there appears to be a group of Dactylourans, called Scalprodensida, that fill niches comparable to squirrels and other arboreal rodents and to some extend, primates.

Top row, right: Dubbed Cathetirhinoids, these curiously shaped Bloëcatherian Arachnotheres are a surprisingly common sight around our settlements in western Miesjeta, seemingly attracted by our activities. These typically small creatures have two long probe like nostrils that sport long whiskers. They have great control over these appendages and can often be seen vigorously moving them while they look for food like a pair of antennae.

Bottom row, left: By far the most well documented rodent analogues of Eryobis are the Triprotodonta, called “Dozjemoigh” by the natives. These creatures are found on every major landmass except for Hatémica and like actual rodents, can vary in size from a small mouse to several hundred kilograms. Triprotodonts are one of the three major clades of the Liomedactylae, the terrestrially dominant group of Trapezostome Anisospondyls and are quite odd at that. Their inhaling spiracles are pointed outwards and their auditory plates are flat and circular. But their most defining trait is their mouth. Like the aquatic Fermourodonts, they have convergently evolved their jaws to work as three mouth parts, with both mandibles coming down on the trapezium below them. Each of these mouthparts sports a single tooth at the tip, earning them their name.

Bottom row, middle left: There appears to be two different kinds of rodent like Effingodactyl Cryptognaths. One of these appears to be very basal on the family tree, possibly splitting off before even the Chalacheiroptera split off. Not much is known about these creatures besides some footage few trail cameras.

Bottom row, middle right: The second line of rodent like Effingodactyls actually resemble hyraxes or small notoungultes more than rodents. Being small hoofed critters that feed almost exclusively on plant matter. They are distantly related to other hoofed Effingodactyls and it remains a bit unclear whether or not this group is monophyletic.

Bottom row, right: The final identified group of rodent like creatures are the Skalisorhynchids, a clade of Eusymmetrodactyl Cryptognaths whose affinities remain unclear, but are obviously part of the "Polyotoalosia". They have a combination of very derived and quite primitive traits among Eusymmetrodactyls, so where and when they came from is a mystery, but by the present they are very successful and widespread, only being surpassed by the Triprotodontid, which often seem to drive them to niches they wouldn’t normally occupy or straight up outcompete them.
