Marsupials and placental mammals are the ones that do not lay eggs.
Monotremes are the only egg-laying mammals, and this group includes just the platypus and the echidna.
T-rex would have mated like most land vertebrate, and after some period of time the female would lay eggs.
Eggs! plain and simple eggs!

No dolphins are not amphibians. Dolphins can`t be amphibians because amphibians lay their eggs in the water and the adults live on land. Dolphins live in the sea only and they don`t lay eggs they give birth to live young.
