Have a really good pteranodon and go to a swamp, then go ham on all the Paramecium that’s there, and you will have HELLA prime meat, TRUST ME ON THIS, THEY ARE THE BEST THING TO GET PRIME MEAT FROM IF YOU HAVE A DECENT PTERANODON
If you know you are going to tame something, or you have something trapped, go to your base and get fertilized dodo eggs by breeding dodos. Hatch them, and kill the babies. Each baby should give 4-6 prime with a decent metal pick, eggs only weigh 0.5, and it takes one or two torches to get them warm enough.
Tame dodos. Make a dodo pit (2x2 thatch hut with a ramp.) Put 1 male any level with 3-4 females any level. Breed dodos. Collect eggs with Whip. Hatch eggs. Kill all the males. Harvest with a Rex or pick. Females go in the pit with the rest of the dodos. LOTS of prime.
Been using my new argie and killing brontosaurus and they get more prime the metal picks. Metal picks do get more but there is a chance is doesn’t get any while on the argie, I consistently get 3 or more prime meat. Please notice this and stop wasting your stam, durability, and your time on the metal picks, use argues!
