Oh, Pachycephalosaurus is pretty cool. It's the big dome-headed one that might've bonked heads like bighorn sheep. Although, honestly, evidence to that is sorely ambiguous. The dome was made of fairly spongy bone (it grew quickly) so it might not've been able to withstand a full-on impact with another one. More likely, these animals went after each other's sides or flanks. |

You know, when I was younger, I was reading an encyclopedia of all the different dinosaurs and after reading one entry for a dinosaur that looked like a young Brachiosaurous (sp?), I theorized that a lot of dinosaur discoveries were not new species, but juvenile and older dinosaurs of already discovered species. I think the entry in question was the Vulcansaurous (again, sp? spellcheck doesn't cover dinosaur names). Nice to know I was roughly on the right track. |

Vulcanosaurus is most certainly a valid taxon. It is a "cetiosaur" grade sauropod. But I see what you mean. |

Do dinosaurs taste like Chicken or Ostrich? |
