Macrocerus's body shape is based on tapirs. Here is my original concept.
This inspiration included the legs but after going to Cromer zoo and seeing the tapirs that they have there, it kind of hit me that they are a lot lighter than Macrocerus is intended to be. They don't have to carry around heavy armour, tusks, reinforced scaly plates etc. When I went back and looked at Rhinos (the main inspiration for the armour plating) I noticed that they have shorter, sturdier legs that enable them to remain more balanced and able to carry greater weight. I applied this to my concept for Macrocerus.
