The same problem, no Quetzal, tek quetzal, Velox quetz, velox tek quetz, Tusoteuthis and alpha Tusoteuthis, with different settings and even without other mods.

I just downloaded this map and went on solo play to spectate and see what the map is like.
First thing I seen was a quetz and trex/wyvern all together and thought, oh! interesting. Right near 2 drops at the snow area.

So they definitely are on it. At least for my solo game!

As I was like "A quetz, alive, near a wyvern!" haha

i run on the Gaming Network server and we don't run a mod for the tek quets, quets, tuso, or any of the velox variants of them and i have see them all over the map. we do randomly find quets walking on the ground so when hunting one be sure to check the ground as well as the sky

I've found Quetz no problem. Haven't really ventured into the deep yet so not sure about Tuso's. The only thing I haven't been able to find are Ovis. Anyone got any idea's where they might be? Cheers

Found ovis in the snow area. but ive been doing dino wipes for days and using a tek transmitter to scan dinos.. never a quetz or a tuso has spawned on the map for us. Im open to ideas please

Ok so heres an update, Ive run at least 100 dino wipes, no quetz of any variety, no tuso, no giga, no phoenix, no griffin, only velox are snow owls and pteras. None of any other variety have spawned. We are running rare sightings mod, s plus, classic flyers, ckf, and a couple eco decor.
Im really at a loss at what to do here. I love the map and dont want to change now, but we wanted to have access to those types of dinos. I need a little help as to what to do here.
Thanks

Its one of the other mods you have installed, as I use no mods at all on my server and all of those spawns have been there from the start. Try disabling one and leaving the others on, dino wipe and then scan to see if they spawned. If they did, then that is your culprit. If they still havent spawned, turn it back on and rinse/repeat with a different mod til you find the one.

Sounds like a good plan, time consuming but I will have to test it. thanks!
