◆ 霸王龙英文是tyrannosaurus rex，有没有简单说法？
Mom: Last up is the group from the cretaceous period.
What does that include?
Child: Hmmm … that includes the tyrannosaurus rex, stegosaurus, triceratops, velociraptor, and spinosaurus.
I know about these!
Mom: Well, tell me about them as we walk along.
Child: Okay. The most famous one is the T-Rex, or tyrannosaurus rex;
he was a carnivore
and could weigh up to 15 tons
and had the strongest bite force among land animals at the time.
He was vicious.
Mom: Sounds scary!
Child: There was also the stegosaurus,
who had massive plates standing along his spine
and his tail had spikes.
He was a quadrupedal dinosaur
and a herbivore with a short neck.
My favorite is the triceratops.
That one was a herbivore who had 3 horns on his skull –
two at the top of his head and one on his nose.
He had 4 thick legs to walk on.
He was normally about 9 feet tall.
Mom: This one looks impressive.
What does the plaque say about him?
Child: I'll read it.
"It was a bipedal,
feathered carnivore with a long tail
and an enlarged sickle-shaped claw on each hindfoot,
which is thought to have been used to tackle and disembowel prey.
Velociraptors can be distinguished from other dromaeosaurids by its long and low skull, with an upturned snout."
Awww… we're at the last one.
I wish there were more.
Mom: What's the last one?
Child: The spinosaurus.
He has a huge fan-like spine,
which is where he gets his name.
The spine was an extension of the vertebrae,
which could grow up to 5 ft tall!
They were connected by skin.
Mom: I think he is my favorite.
That was a great tour through the dinosaur section.
I'm impressed that you knew so much about some of them,
but did you learn a little more today?
Child: Yes! Let's go to lunch.
I'm so hungry I could eat a dinosaur!
