Re: Amargasaurus...

I would hae to agree with Gregary Paul in his interpretation (maybe not 
specifically) of Amargasaurus, in that he thinks it's some sort protective 
sheath core...looking like a porcupine's back. The large duo neural spines were 
possibly housing something larger, maybe a sail. I'm currently working on a 
interpretation for a frill reconstruction. Science hasn't yet pinpointed if 
it's sex-specific, but I wouldn't doubt that either.
