Triceratops and Torosaurus become a thorny issue

I was nervous when I saw the title, Triceratops and Torosaurus become a thorny issue - chicagotribune.com: "Triceratops: Beyond extinct". Triceratops has always been my favorite dinosaur. Triceratops and Torosaurus are likely the same species, at different maturity levels. This quote made me less nervous:

"Triceratops: Beyond extinct"; "You'll get a lot more hits on Google if you type in Triceratops instead of Torosaurus, and if you don't understand why that matters, you're, well, a dinosaur. So let's agree: A Triceratops isn't a baby Torosaurus — a Torosaurus is a grown-up Triceratops."
