A Tyrannical Romance - The Wild Side - Olivia Judson - Evolution - Opinion - New York Times Blog: "Male crocodiles have a penis — just one — which, most of the time, they keep tucked inside their cloacae. (In most species of crocodile, it’s hard to determine the sex of living animals without an intimate exam, never mind dead ones.) Compared with the mammalian penis, the crocodile’s has an oddity: sperm is transported along an external groove, rather than through an internal tube."
But did T. Rex have one? Nobody knows for sure. You'll have to read the article.
