Scientists find how lizards regenerate their tails

It’s one of the most remarkable adaptations in the animal world – growing a tail or a limb. Some lizards do it, salamanders do it, and by learning how they do it, we may soon be able to do it as well; with technology, that is. A team of researchers have discovered the genetic “recipe” for lizard tail regeneration which, at

Carnotaurus had puny arms, incredibly powerful tail

If you think that T-Rex had laughable front limbs, you’re in for a treat: even he would be amused by upon such puny arms. However, the shortcomings Carnotaurus had more than made up for its very muscular and powerful tail, which made it one of the fastest hunters to ever walk the face of the Earth.
