If you guys need any help with dong the cave ill be happy to respond if you just say what your having trouble with and what difficulty your playing on!
What about kaprosuchus. They can grab scorpions and spiders with it's bite while running away from them. And they are fast land and water creature making it useful. My honorable mention list: Pulmonoscorpius,parasaur and other herbivores that can fit in caves
My favourite strategy is to bring one tanky parasaur and two to three raptors. Make sure the parasaur is in the front, and everything should attack it whilst the raptors shred them. No high level tames needed :) Of course, the cave can be done on foot or simply using a raptor aswell, but if you really want to play it safe, a tanky tame and some backup is all you need.
For sure man it’s fast and it has decent damage, the best part I find about it is it’s jump height and it’s ability to jump on animals and pin them down in the cave
