Re: Triceratops



FYI: Peter Dodson was Cathy Forster's academic advisor while she wrote the paper for JVP. She consulted with him a great deal, and mentions him in the acknowledgements. I don't know if he agrees with her or not, but the ideas were presented to him.

As far as the number of characters goes, what is a good number? If you have too many, why not call them a different genus? Too few, and they are the same, but the characters she uses seem to hold for most specimens of Triceratops. When you think about the biological concept of species, would the two types interbreed in the wild? Interesting thought to ponder.

With the Psittacosaurus, good question. Is there any stratigraphy done for each specimen?
