Alright not exactly my tip, but heard this from the YouTuber pterafier. He said that using a Crab with a Turtle with C4 strapped on it is a good seige device. Put C4 on Turtle, then use Crab to throw the Turtle at a base. Detonate the C4, blowing up the base where the Turtle is at. I'd recommend watching Pterafier, he has a lot of tips on his channel.
Karkinos is also great at defense, is someone is trying to soak your turrets with stegos or turtles you can toss them away and win a lot of time while the atackers have to go take their tames back. Especially if near a ledge or cliff
If you're carrying a tamed Doedicurus in your claw the Doedic will automatically start harvesting any stones you hover him over. Just start pumping points into your Doedic's weight because it will stop at about half of its own carry weight. I've yet to discover another tame it will work with though...
Be careful when carrying a Dino that has a tribe mate mounted on it. I was walking up a hill carrying my anky with a tribe mate on it and they went under the map and died. RIP ANKY AND SHINEHORN. Tribemate was eh anyway.
