In search of Terratherium

I got a whole slue of sketches from that old Monster Hunter contest.  The contest was a bust, but it was fun playing around with designs.

I was primarily trying to fuse a Galapagos Tortoise with a Giant Sloth. I also tried referencing snapping turtles, armadillos, as well as prehistoric armadillos.

I wasn't sure of what to call it, so I took the Giant Sloth's scientific name Megatherium and switched out the "Mega" for "Terra".
