So I tamed two Sarcosuchus, right? I put my female, Cuddles, and my male, Brutus, into a pen and let them do their thing. Afterwards, I get the egg and incubate it. It had about 5 minutes left when I decided to go on a hunting trip with my Megalodon, Sharkira and Cuddles. Long story short, Sharkira died and when I got back after dying twice and taming a Ichthyosaurus, I saw a juvenile Sarcosuchus running around. Apparently they had hatched, and I say they because I had twin sarcos!
