Bird Evolution

[Grant Harding <granth@ziplink.net>]

Hi everybody,

I'm trying to come up with a sort of chain for the evolution of modern 
birds. I would like as many people on this list as possible to send me 
their idea. I would like it to be written in a way similar to this:

*This animal* evolved into *that animal* evolved into *another animal* 
evolved into modern birds.

Please make sure it is chronological - e.g. Early Cretaceous cannot come 
before Late Jurassic. Please start no farther back in time than the 
origin of dinosaurs. I would like to get as many opinions as possible. 
Please send me yours!
Thanks,

-Grant
