To get the final torque AND stretch on the bolt, you tighten the bolt a given number of degrees of rotation. This is what the torque angle guage is for, accurately measuring the degrees of additional rotation (typically accurate to a degree or so). The Reason For Not Re-Using Stretch Bolts.
T. rex had a mouth full of serrated teeth; the largest tooth of any carnivorous dinosaur ever found was 12 inches (30 centimeters) long. But not all of the dinosaur's teeth served the same function, according to a 2012 study in the Canadian Journal of Earth Sciences.
Being a dicynodont, Lystrosaurus had only two teeth, a pair of tusk-like canines, and is thought to have had a horny beak that was used for biting off pieces of vegetation.Lystrosaurus was a heavily built, herbivorous animal, approximately the size of a pig.The structure of its shoulders and hip joints suggests that Lystrosaurus moved with a semi-sprawling gait.. maccaigi is the largest and apparently most specialized species, while L. curvatus was the least specialized. A Lystrosaurus-like fossil, Kwazulusaurus shakai, has also been found in South Africa. Although not assigned to the same genus, K. shakai is very similar to L. curvatus.
