I did Therizinosaurus in this zebra-stripped guise right from the first painting I did of it. Then, Dorling Kindersley -under my supervision- took the idea to 3D levels in the the DK “Encyclopedia of Dinosaurs and Prehistoric Life”, a book that Darren Naish and I have special memories of . I like to keep some consistency in the depiction of “my” animals… in a new version to be published soon, I have extended the feathery coverage… it is indeed a strange animal. I have a cast of one of its claws and with the keratin cover, it would have been measured a metre or more. I also have a cast of a therizinosaur nest… 
This is a sketch reconstructing what was inside one of the eggs in exactly the same posture. This therizinosaur was not Therizinosaurus itself, but it gives a good idea of what might have been a real Therizinosaurus embryo.
“in a new version to be published soon,”
Out of curiosity, are you referring to the big book you’re working on w/Bakker or something else entirely?
Yes… but I’m not going to be able to show anything until we are ready and going to print! Watch this space.
Can’t wait!
