First Look – IDW Josh Adams Doctor Who comic preview is a Tyrannosaurus Rex Matt Smith's new companion?

A little bit of Doctor Who fun for you courtesy of IDW comics, the image above is from a series of previews done by Josh Adams (son of Neal Adams) who is taking over art duties for the IDW book from Issue #9. The question I have is the T-Rex the Doctors new companion? Rest of the images after the jump.
