I am a paleontologist

The awesome alternative rock band "They Might Be Giants"  has a new science themed album out and one of the songs is titled "I am a Paleontologist."  The lyrics are as follows:

I love diggin' in the dirt 
With just a pick and brush 
Finding fossils is my aim 
So I'm never in a rush 
'Cause the treasures that I seek 
Are rare and ancient things 
Like Velociraptor's jaw 
Or Archaeopteryx's wings 

Now all the kids 
Who wanna see 'em 
Are lining up 
At our museum 

I am a paleontologist 
That's who I am, that's who I am, that's who I am 
I am a paleontologist 
That's who I am, that's who I am, that's who I am 

Could it be an herbivore 
Crushing plants with rounded teeth 
Or ferocious carnivore 
Who moves so quickly on its feet 
It's like pieces of a puzzle 
That I love to try and solve 
It's so fun to think about 
How a species has evolved 

And all the kids 
Who wanna see 'em 
Can check 'em out 
At our museum 

I am a paleontologist 
That's who I am, that's who I am, that's who I am 
I am a paleontologist 
That's who I am, that's who I am, that's who I am 

Is it a T-rex? (I keep digging, digging, digging, digging) 
(Digging, digging, digging, digging) 
Maybe a Triceratops? (Digging, digging, digging, digging) 
(Digging, digging, digging, digging) 
Or a Carnotaur? (Digging, digging, digging, digging) 
(Digging, digging, digging, digging) 
(Digging, digging, digging, digging, diggin') 
Pachycephalosaurus? 

I am a paleontologist 
That's who I am, that's who I am, that's who I am 
I am a paleontologist 
That's who I am, that's who I am, that's who I am 
That's who I am, that's who I am, that's who I am 
That's who I am, that's who I am, that's who I am
