Stegosaurus is my favorite dinosaur, so my daughter Abby drew one for me. While cutting it out, I got to thinking about it’s tail. Reading about Stegosaurus, I learned that they have two rows of two spikes on their tails, but Abby’s looked more like an Anklyosaurus tail to me. Which got me thinking about familys of Dinosaurs and whether the two of them were related. Turns out that yes they are both from a larger family of armored dinosaurs. Pretty cool, huh?
