Dinosauroid

Ever wondered

......what the descendants of the dinosaur Troodon would look like today if the theropod had survived the end-Cretaceous mass extinction.......

Laelaps forwards us to an interesting reincarnation of this thought experiment (and the above picture):

What are the odds that intelligent, technically advanced aliens would look anything like the ones in films, with an emaciated torso and limbs, spindly fingers and a bulbous, bald head with large, almond-shaped eyes? What are the odds that they would even be humanoid?

Is answered in one of those links.
