They are found a lot around the snowy mountain. Don't listen to the map, they are more common where it says 'very rare.'
Ovis
The ovis is a sheep-like creature that many survivors find useful in farming. It can be found in the grasslands. While rare, it can be tamed simply by feeding it one Sweet Vegetable Cake. This sheep can be sheered with Scissors to obtain Wool, or killed to obtain Mutton. While the ovis can be mounted, it is not an ideal mount for transport and provides very little use once mounted, other than its ability to climb up steep inclines.

Extremely rare. Best place to find these is in the stomach of another dino
Seem to be found mostly in the snow. Quite rare, but definitely worth dropping what your doing if you find one.
They sound like mincraft sheep.
The frist time I saw mine, I was on the edge of the redwood forest near a small stream. I picked it up with my Argent, so if you want to take it home and save it for breeding or tame meat that's the way too go.
I accidentally killed a level 150 ovis by bola’ing it then impaling it with a spear. I wasn’t even aware of how rare this actually was and I thought about killing everything in sight because I was desperate for hide.
These things are in mobile I found one in the snow biom and put it in argys stomach

Easy place to find in Fjordur is Jotunheim, go SouthEast. The cold there is killer but the best way to stay alive I've found is with full fur gear, an otter around your neck, Frio curry soup to keep help with the insulation and med brews as well as blood packs on your quick slots. I recommend at least bringing 20 or more med brews if you plan to stay alive longer than 2 min.. a HOT tek canteen will work wonders if you have one.
Use a desmodus(Bat).
WATCH OUT for microraptors and other predators!!!!
OVIS are an instant passive tame with sweet vegetable cake!
Very rare, rather you to breed it for mutton farming
Sigh..... all those ragnorok players with their ovis’s. Why are so rare on the island?
