Almost got it

This is Miragaia longicollum, the stegosaurid with the longest neck. He has 17 neck vertebrae which is much for a stegosaurid. He had this probably because trees grew taller in his time and evolution had to find a solution for still being able to reach the branches.
Miragaia is estimated to be 6 metres in length. We only have one specimen... well... actually half a specimen: only the first part. The tail, hind legs and back are missing so we don't know if it had plates on his tail or spikes. I choose for the latter because it makes him look more badass, also he has a spike on his shoulders.
