The Final Result:
So I looked. Below is a selection of other artist's reproductions of Minmi I found using Google Image Search:
Not to be confused with our cute little ankylosaur:
As you can see, there is a huge variety in Minmi's shape, musculature, armour, spikes, and colour. So much so that each picture looks like a different animal! This is strange as about 95% of the skeleton has been found. Some artists chose to represent Minmi more like a stegosaur while others chose an ankylosaur-like style. I chose more of a nodosaur-like shape for my painting. But the question is: which one is correct?
So long, and one more Min-mi for the road!
