I've missed out on some awesome Art Evolved shows over the last few months (understandably), so I'm getting back on ye olde bandwagon for the March therizinosaur-themed show. This is a draft of Therizinosaurus I whipped up today. A couple things worth mentioning:
1) Notice that it's got a plantigrade foot. Andrea Cau turned me on to an interesting paper (via his excellent post) that suggests, based on alleged therizinosaur footprints, that these big theropods had bear feet. It's certainly more plausible than the "knuckle-walking" strategy I suggested like two years ago on this humble blog. However, I do still endorse a chalicothere model, so this therizinosaur is comfortably sitting on his haunches.
2) If that center claw is three feet long, then the whole animal is between thirty and forty feet long. I've never been comfortable with uber-huge estimates for Therizinosaurus. The largest maniraptor known from good material s Gigantoraptor, and it's almost thirty feet long. What I've done to combat oversizing the animal is to shorten the neck and tail. If we're talking about an animal the size of Allosaurus, it can probably reach its leafy greens just fine without a sauropod-sized neck, thankyouverymuch.
3) Only the arms have feathers (right now), and even those may largely disappear. Giant animals with insulating feathers? Probably not. I may give it very sparse feathers along the back, flanks, and arms.
4) It will be to scale with the two other therizinosaurs that I'll be including, Falcarius and Nothronychus. I'll give you two guesses as to where I'm going with this...
