This bunker is a very interesting one. I have never been in it (in real golf) but several members of the groups I have played with have. All the bunkers at Kiawah are pretty much firm sand, they are carved out of the dunes, haven't seen a T-Rex in one before but you can get great spin on the ball hitting out of them from greenside and really a shot out of the fairway bunkers play like a shot off the fairway. The only issue is that sometimes, like in this case it is hard to hit more than a wedge out of them, similar to some of the traps in Scotland. My suggestion to you is not hit it in them anymore.
