Description
To be honest, I have no idea what catopsalis looked like. I was working on really limmited references (a speculative illustration of the skeleton) so it's probably highly inaccurate... but fun to draw anyway. I've always liked fleshing out animals from skeletons, ever since I was a kid.I'm not exactly sure what period in Earth's history catopsalis is from... some sources say the late Certaceous, others say the early Paleocene. I just say, around the time the dinosaurs became extinct, either before or after. *NTamura informed me that there were several species of catopsalis, and that some existed before, and some existed after the Cretaceous-Tertiary extinction.
It belongs to a large extinct order of mammals called the multituberculates. The multituberculates were much like rodents - small, abundant and with large chizzel-like incisors. However, they developed their rodent-like characteristics independantly, and were not closely related to rodents. They were plentiful during the Mesozoic - the age of dinosaurs - but dwindled into a slow extinction as the eutherian mammals took a hold of the Earth.

The idea with Multituberculates is that they were rodent-like but probably had more sprawled legs, so I think you did both those things. So this 100% fine.

You can move the animal to the right side a few and add the highlight to an eye and shadow on tha background and thethe picture will be more live

The genus Catopsalis is divided into several species (about 8), some from the Late Cretaceous of Asia, some from the latest Cretaceous of North America and others from the Paleocene of North America. It might be that the genus originated in Asia and spread trough North America by the time of the extinction of the dinosaurs. I would say almost any reconstruction of a rodent like creature will do as Catopsalis is only known from fragmentary materials (skull fragments and teeth)...

Where do you aquire your knowledge? I've been searching for ages for info on this creature. Info like what you provided is scarce, to put it lightly.
Thanks for the info! Its much appreciated.

I usually go to the primary sources (scientific journal articles such as Vertebrate Paleontology, etc...) whenever available. Having access to an university library helps.

Ah, in that case I better work hard at my studies to get accepted in to a uni (you need a student photo ID to use the nearest uni library). Though I'm not sure if the ones available here really have any sections on paeontology. I can only hope so.
I better look harder for the articles you speak of. I know you've helped me before, so I don't want to bug you. To be honest, I'm just not that good at using google.

Try google scholar. That will point to science articles although you'll need subscription for most of the journals.

Ahh... those subscriptions have frequently caught me out when searching. Don't have any money to spare and don't have a means of paying online for things (my bank account sucks).
There are some free ones though? I will look for google scholar - I've never heard of it before so its something new to try! Thanks!

It reminds me of my dearly departed gerbil that was about the same color
