As advised I killed off all diemetradon's with no hatchlings and got a few to spawn after a pass or two. First was poor and second was rare! I count myself lucky as there were 2 others looking for then when I went. I have to admit I was hoping it would be a bit bigger but it's still really nice. You don't see many being used in battles and to me that's a plus. :)
