This is the largest black caiman skull in any museum collection in the world. In the second image, the specimen next to it is the skull of a ~15 foot Nile crocodile from Uganda ( link).   |

Scotty and how it would compare with the average and world record African bush elephant. The mass of ~10 tonnes for Scotty may be debatable, but in any case, this is what a 10 tonne T. rex might look like next to our biggest extant land animal. © @ Paleop.  |

Crocodile and hornbill skulls. Archosaurs ftw. Image by T.A. Holmes. (I'm gonna be honest with y'all, I can't tell which exact species they are.)  |

Skull material from Plionarctos (recovered from the Gray Fossil Site) and a modern spectacled bear skull ( link).  From the same site: skull of the extinct red panda Pristinailurus bristoli compared to that of the modern red panda ( link).  |

So this is how Deinonychus and Tenontosaurus stack up. Gives me a few different thoughts. © @ Matt Dempsey.  |

It sound like the young tyrannosaurus got the worse of this encounter but the fact that it even seemed to have attempted to attack an adult triceratops strongly dispels the idea that tyrannosaurus rarely attacked adult trikes.
IMO I am guessing that tyrannosaurus targeted triceratops in the same way tigers target boars. 60+ percent of trikes hunted would consist of young/subadult individuals but 30-40 percent of trikes would have been adults.

Even without the Dueling Dinosaurs as potential evidence, I see no good reason to think T. rex was only hunting adult Triceratops (and other adult herbivorous dinosaurs) once in a blue moon. And if this turns out to be an actual predation event, it would only bolster this sentiment.
I just can't wait for further study on the fossil find, since there seems to be a lot going on with these two specimens (and also so we can really confirm whether or not they were fighting). The fact that the young T. rex had many of its teeth wrenched off and had a broken finger (which might be expected if young T. rex used their forelimbs more for predation) while the Triceratops had teeth lodged in its spine is intriguing.

Is there any way I can put in a request for a size comparison image between Kentrosaurus and Styracosaurus?

Well, there's nothing I can say other than the fact that no one's really active at the moment to grant you that request. The few people who actually are active don't make size comparisons.

I think one day I'll go through this and try to make more specific threads like dinosaur size comparsion, carnivora size comparison, ect because this thread is huge.
