Did the T. Rex have an amniotic egg? Question 15 options:

Probably not because there is no history of closely related animals having an amniotic egg.

It is quite likely because lots of animals in the past have had amniotic eggs, so the T. Rex probably did too.

It is quite likely because both the caiman and parrot have an amniotic egg and they share a recent common ancestor with the T. Rex

Probably not because the T. Rex is no longer living.
