Still Waters Posted January 17, 2018 #1 Share Posted January 17, 2018 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. https://phys.org/news/2018-01-dont-turtles-tail-spikes.html 2 Link to comment Share on other sites More sharing options...
seaturtlehorsesnake Posted January 17, 2018 #2 Share Posted January 17, 2018 hey, yeah! what gives? neat article, sea turtles interestingly enough only fit one or two of the traits required, depending on the species. 1 Link to comment Share on other sites More sharing options...
oldrover Posted January 17, 2018 #3 Share Posted January 17, 2018 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. Link to comment Share on other sites More sharing options...
