Flat-Tooth Calf

Found the Flat-Tooth Calf in Talador, Cords. 53.4, 82.2 He was a primary RARE

I found some near Terrokar Refuge Island.   I passed maybe at least 10-12 of them.   I think it's just a timing thing.   

These spawn in two places: SE of Auchidon, Terrokar Refuge Island.  However, they don't spawn in both places at the same time.  If you only see the critters at your location, go the other location.  There should be around 7 in each area. 

I got a blue near Auchindoun a few minutes ago (Moon Guard server),  B/B breed and thought about trying to find another one to upgrade, but I think I'll leave him as is.  He's a cute little guy and it doesn't really matter if he's not a better breed as I'm not likely to use him in a battle.

Found a rare B/B and uncommon H/S at the same time.  About 2 months prior I caught my first common(after a guildie tipped me off that he saw two and caught one) one and raised it to rare, also a B/B.

I think there are normally two spawned at the any time.

Got one the first time I checked but only an uncommon - oh well battle stone here I come!

The minute I landed on Darkfall Island, I found a common Flat-tooth Calf. Couldn't find other one after that.

tough to find but today there were 3 outside of auchindoun around the waters near the waterfall, 2 uncommon and one rare. 1:45 server time hope this helps and good luck

This little guy was difficult to find. I got my common one (finally) next to his mama. (44,91) Be sure to not AOE when you kill mama or you will be very, very sad. 

Found my first Calf nere the waterfall at 65,64 rare quality. 

Its a tricky little one to find! 

I made two passed of both areas and was about to leave when I got mine by the waterfall, I figured, that's where the actual monsters hang out, that's where I should be able to find one.

I found 4 @ 64:57 @ 12 noon server time. I had looked around a lot before with absolutely no luck.

Was lucky enough to find a grey one at 64.83, 56.53  (Duskfall Island).  I'd been riding around for about 25 minutes before I found this grey one.

I have also found these guys in Talador along the shore starting at 64.5/63.1 where the Riverwallower beasts are grouped...and continuing up along shoreline to the north, on both sides of river.

Found my uncommon on a tiny island/sandbar in between Achindoun, and Deathweb hollow (SE). There were two riverwallowers fighting beside samesaid tiny island (but of course, they might be dead/pre-respawn) when you come to it. Sorry, I don't have the co-ords app, so hopefully descriptivness does the trick.

mine is equal speed and power (at 221) and his health is 1480.

Edit: Just spotted another uncommon in the same river, this one just below sunsworn camp.

I saw two near the water SE of Auchindoun. Other than that, they're pretty scarce. Hope this helps!
