"Large animals have slow birth rates. Alligator. "
Actually, you offer a poor example. Alligators, after reaching maturity will lay their eggs each year, in rather a large clutch. What makes you think they are slow to breed?
You're just guessing. Your other examples, like Elephants and horses, have no relevance, since they are mammals.
Guessing doesn't get it. The bottom line is that you have no idea how often Rex bred. You don't know if it was an egg-layer or a live-bearer.
Essentially, you don't really know anything at all about Tyrannosaurus Rex.
Thanks for playing.
It's a fine example. Alligators only have one (Spring) breeding season. They breed slow and they are little changed in 200 million years. Hmmm...
>>Essentially, you don't really know anything at all about Tyrannosaurus Rex.<<
Neither does anybody else, essentially.
Thanks for playing.
'Course, now that we have that T-Rex soft tissue, that could change in the next few years.
