Where are the Gigantoraptors

Hello,

I recently wanted to tame a Gigantoraptors and I went and explored the southern part of the map, where there are the most Gigantoraptors but I couldn't find even 1 Gigantoraptor. What is going on? Where are they? I've looked on YouTube what could be going on but the only thing I've found were Gigantoraptor spawn locations (There were no Gigantoraptors of course) so Reddit is my last hope in finding a Gigantoraptor. What am I doing wrong? Where should I look more? Please help me
