英式拼寫

You must have to be an amazing anatomist. So you must have to know the anatomy of so many different dinosaurs to be able to work out what it is you're looking at.
Yes, but sometimes it's difficult. For example, here, we have two bones of one dinosaur. Can you figure out what they are?
Well, I'm a human anatomist, so this is stretching my expertise so more to ask me to identify dinosaur bones.
And these ones are not very well preserved, I'm sorry.
Brilliant. You know, they're fairly kind of flat pieces of bone, so I would think maybe this is part of the skull or the jaw. Am I anywhere near?
Yes, you're absolutely right. So what you have here are two lower jaws of a duck-billed dinosaur.
Oh, brilliant, so they'd come together in the midline or somehow.
Yes, but they actually come together right here.
The other way round. Brilliant.
