" It's very safe to say that T Rex had slow birth rates. That's not made up, that's derived.

Large animals have slow birth rates. Alligator. Whale. Horse. Elephant. Etc."

You said the T-Rex's rate was slower than the alligator or the elephant. You still have nothing to back that up with.

It's actually pretty amazing what a few point mutations in the Hox genes can do.

On the contrary, you have nothing to support a faster T Rex birth rate, whereas I can show that alligators breed slower than smaller reptiles.

D'oh! Don't you hate it when the tables are turned?!
