-So, let's start up. T-rex usually an adult, its skull¹ is a great weight to measure because it's so big. But in babies, the skull’s gonna be thinner. The rule is always that the orbit is gonna be larger. Also when you look at human babies, we notice they're about three heads tall, whereas in an adult human which is anywhere from seven to nine depending on how tall they are. 

 

-Do you find yourself as you’re looking at other people's reconstructions³ and thinking, “oh god, they’ve got that wrong”?

 

-Yes. There are a bunch of people who are out there, who were coming from maybe film or special effects or something like that. They are doing this kind of work from a lesson-formed background. So I'm very privileged to work with a scientist. And that's definitely an asset that I don't dare forget.

 

-He is looking nice, this little T-rex.

 

But with limited fossil remains⁴, the reconstruction² has room for creative license⁵. 

 

-Can you draw me another baby T-rex based on the same evidence but taking it off from a bit of a different direction?

 

-Sure. Let's do the same thing. We have a head. There’s a lot of evidence that some of them might have feathers, and that maybe some of them, when they were young, would have had some sort of downy covering that would have left in adulthood⁶ so that it would have been shed before they were fully⁷ grown.

 

-This little baby is looking extraordinarily⁸ bird-like. It has really long legs. Is this a reasonable interpretation⁹?

 

-There is nothing that says that it can't be this way.

 

-Right. They are fantastic. The same creature but they are very different. Even without the feathers here, the length of the legs is quite extraordinary in this one. And I love the feathers. I mean that just immediately makes it look like a completely different creature. It shows you that there’s quite a bit of room for artistic¹⁰ maneuver¹¹, I think, in these reconstructions.

 

-Yes. Definitely. Definitely.
