I think these claims cannot be proven from skeletons. Different skeletons could be growth stages, and very similar skeletons can be different species. There is simply no way of knowing without having living populations to study. I think the whole issue is a futile and unproductive word-game.
Ahh, makes sense. I couldn't imagine someone looking at it closely enough to actually draw it in that colour scheme. But I like it. It certainly doesn't come across as "obvious", but then, you rarely do.
Maybe - It's very hard to conclusively prove these things from fossil remains and I find the whole "lumping-splitting" game a more-or-less semantic misuse of time and effort. If this animal indeed proves out to be a grown-up Triceratops, call it the "animal formerly known as Torosaurus" instead
I wouldn't be surprised if Titanoceratops ouranos would soon be considered as the oldest, mature form. Some find it as a relative to Eotriceratops xerinsularis and Ojoceratops fowleri which these two are found to be either the same species in the former genus or as Triceratops. If true in either case, Titanoceratops could be lumped in.
On the other hand, there are those who are against the notion some dinosaurs were just simply life stages (George Olshevsky is a prime example); then again, infant apes and humans in skeletal features look remarkably the same until they all grow up.
It wouldn't be weird. Some genera, like Homo and Canis have been around much longer than that. And I am not saying that they're all one species, I am saying that they were as little as two or three species of Triceratops which the adults look very different.
Well, remember this "comment thread" was made before the other major study that "proves" toro is not an old trike. But just because they may look distinctive, doesn't mean they're that far apart. Look at the Cougar and the Jaguarundi. While you can argue that might be better off as two separate genera that very close (and I am sort of on the boat with it), these two are classified as species of Puma and most scientists don't seem a problem with it.
