@ GMATNinja,@broall
By going through POE, we can reach OA as A. But option A looks like a faulty comparison. We are comparing species of dinosaur with warm-blooded mammal’s metabolism. Correct comparison should be with the metabolism of species of dinosaur with warm-blooded mammal’s metabolism.
Example- I have more money than Sam(has). Here has is understood. The sentence is correct.
I have more money than Sam's.---> This is incorrect. We cant compare I with Sam's money.

Hi sunny91, let's take the following example:

I have a better car than Sam.

As you've suggested, this is a correct sentence and is equivalent to:

I have a better car than Sam (has).

However, if we have a sentence:

I have a car better than Sam.

Now this is an invalid sentence, because this is now comparing car with Sam. We fix this sentence as:

I have a car better than Sam's.

This is a correct sentence, since the way we need to read this is:

I have a car (that is) better than Sam's (car is).

If you notice the (hidden) clause in the above sentence, the clause is: that is better, where that is referring to car.

This hidden modifier now changes everything! Basically "I" does not even figure in the comparison! It is just the car that is being compared.

Now, let's analyze the following:

Some scientists contend that many species of dinosaur had a metabolism more like a warm-blooded mammal’s than a cold-blooded reptile’s.

This is a correct sentence, since the way we need to read this is:

Some scientists contend that many species of dinosaur had a metabolism (that is) more like a warm-blooded mammal’s than a cold-blooded reptile’s (metabolism is).

Again, notice that it is just the metabolism that is being compared.

p.s. Our book EducationAisle Sentence Correction Nirvana discusses this modifier aspect of comparisons, its application and examples in significant detail. If someone is interested, PM me your email-id; I can mail the corresponding section.

Hi experts,

Would replacing dinosaur by dinosaurs in the correct answer make any difference?

ellipsis in comparison- Shouldn't the omitted words be present in the first part of the sentence in the same form?
In the above sentence, the verb has is not present in the first part of the sentence.

Hi Skywalker18, it would be slightly simplistic to believe that in ellipsis, omitted words should always be present in the first part of the sentence in the same form.

In fact, in certain conditions (especially with the to be forms of the verb), even a tense change is allowed.

Following is a correct sentence from OG:

Heating-oil prices are expected to be higher this year than last.

This is equivalent to:

Heating-oil prices are expected to be higher this year than (Heating-oil prices were) last (year) .

Note that the tense changes after than (simple past).
