I spent 2 hours trying to tame a ankylosaurus and was succesfull. Did some exploring with it following me around and it proved to be a very usefull and strong dino, damn near indestructible with all the spikes on its back and the club for a tail. Next day i logged in and it was their waiting. Went down to the beach to get on my boat and spent a few minutes going through inventory boxes. Next thing I know I get a pop up saying my dino is dead! I found him stuck under my boat trying to reach me at the top of it. His dumb ass drown under the boat! A few days later I tamed another one.......same damn thing happened!
