Given thenew dinosaur fossil find in South America, it would be interesting to know if a similiarity exists given relatife sizes of each as to whether the recent one has Chevrons in it’s vertrabae or tail section.
Just asking and wondering given the fact that they are responsible for facilitating ‘Heat’ distribution in an easier manner.
Now the Critical Question 🙂
WHY do so few large species of Dinosaurs NOT used them or for that matter as a SURVIVAL of the Fittest tool ???
What advantage would it have conferred ????
Put those brains to work, please !
