（单词翻译）
The questions about Louis's baby T-rex run even deeper than its appearance. With such limited fossils, some scientists have actually questioned whether the bones might belong to a different species of dinosaur1 entirely2, something like a T-rex, but much smaller.
-Your presenting of a mounted skeleton of this baby T-rex, and this is the first baby T-rex that's been found and has been put on display. How can you be sure that it is indeed a T-rex and it's a baby, because bones change as
juveniles3 turn into adults.
-You can read the characteristics of the bone tissue. And that can tell you if the animal is a full-grown individual or if it's a baby, a very young individual. So we know that. Perhaps in the future discoveries may prove that there was another species of tyrannosaur that
essentially4 lived together with T-rex, and then maybe this is a baby of that particular species. But at the moment, with the information that we have, it seems that the most reasonable hypothesis is to say this one represents a baby of a tyrannosaur’s racks.
-I think that you’re quite brave to put something to put something like a baby T-rex in this exhibition as a mounted skeleton because there is nothing to compare it with.
-It's our responsibility to make sure that people understand that things are not written in stone. And our scientific conclusions change as we gather more evidence.
Back in New
Jersey5, the T-rexes are nearly complete. And Louis has come to inspect them.
-This is phenomenal, you know, it’s
awesome6. This is fantastic, really fantastic.
-Everything you thought it would be?
-Better, better.
-Good.
-It's hard to describe but I feel that it’s very dynamic, you know.
-We brought the right hand and foot over the centerline court, (-Yeah, I can see that.) And there’s a lot of, quite a bit of movement.
-I’m glad you like that, Luis.
-I think it's phenomenal.
