Its a griffin wearing a tek helmet that looks like an argentavis

It’s an owl on steroids.

To the person who asked if they’re in mobile, yes they are (with the new update to make it Ultimate Mobile Edition) but you have to pay for the DLCs that have them.

Found in the snow biome of Extinction.

Wait these things are in mobile?

With my experience, in extinction and lost island, look in the arctic, gen 2 up on hills, and I only find them I fjordr on random hills - FangClaw

These guys can be found in the top left corner of the map in fjordur

Where do I find I found only 1 ever

You can find it in the snow, it can be found in a group of two (not sure if here can be more) sometimes the group gets split up
