Why don't turtles still have tail spikes?

We're all familiar with those awesome armored giants of the Jurassic and Cretaceous periods - Stegosaurus and Ankylosaurus - and their amazing, weaponized tails. But why aren't similar weaponized tails found in animals living today? In a study covering 300 million years of evolutionary history, researchers from North Carolina State University and the North Carolina Museum of Natural Sciences found four necessary components to tail weapon development: size, armor, herbivory and thoracic stiffness.

hey, yeah! what gives?

neat article, sea turtles interestingly enough only fit one or two of the traits required, depending on the species.

We have just lost several species of very large hirnd and tail clubbed land turtles in the last few thousand years. Which strikes me as a shame.
