Just found out they deal more damage against herbivores than carnivores. Not sure on the percentage though.

When breeding two max level rexes to have a super baby, DON'T EAT THE EGG!!!! I've done this twice on accident(meaning to drop it) and each time it takes me a couple seconds to register wtf I just did and then I have to wait to mate again. Sad day. Weekend ruined. Great way to start off the new year! Lol

FOR AN EASY TRAP:
1.build 3 stone foundations, 9-12 stone walls, 6-9 wooden ramps and 5 stone dinosaur gateways

2- place gateways in a rectangle formation(with one ‘end’ missing as you only have 5 gateways)- the below pattern represents the formation required
x represents the side missing
— —
I X
— —
3.place the foundations on the missing side to complete the rectangle
4. Place walls(3 high) on all foundations
5.starting at the top place ramps leading to the ground the tops of all walls
Congratulations, your Rex trap is complete now all is left is to find that juicy high level and bait him up the ramp where he will be trapped.

Rex baby consumes meat at about 1 meat per 50 seconds. Each meat gives about 50 food, with a food drain of 1 food point per second. So.. 1 meat = 50 seconds of feed. 1 stack of meat is 1000 seconds/16 min. A stack of meat takes 12hrs to full spoil. So.. on 1x, at 6% maturity, a baby rex can be left to fend its own till juvi... this is even with a 2 hr safeguard to be very safe. Honestly... 5% would work also. Hope these statistics help!

All around good game, I use them for gathering hide and meat but have spares for an exceptional kibble farm, great for boss fights
