Extinct animals size

Quote:There are people who like veggie beasts but usually predators have more fans. Let me put it this way.. as Ian Malcolm (Jeff Goldblum) says in Jurassic Park -- "Dinosaurs had their shot and nature selected them for extinction". 

This is where I would disagree with Jeff. After all, some dinosaurs continued to evolve and we see them around us as birds.
Sadly I think it is the sauropod line that was lost.

The barapasaurus has "spines" down its back like an iguana. Were they soft or hard. Iguanas are vegetarian as adults, but they are much smaller than the dinosaur. Interesting that this was a primitive sauropod. The more evolved ones lacked spines.
