Random dinosaur posting: Amargasaurus

[gabester]

I know that the paleontologists know their stuff and have good reasons for doing things they way they do, but I have to wonder with dinosaurs how they can come up with all these species that look nearly identical except for different sizes and weird bone deformities why it wouldn't be more likely that there are many fewer species? Just as with humans you sometimes get six fingers or toes, or an extra set of teeth, or albinos.
