R. Robustus was a hunter? (I wrote this text based on two differents points of view about the Repenomamus Robustus. The first one is a text that defends the idea that R. Robustus couldn't be a hunter. The other one is a lecture in which the professor refutes the text arguments) The professor disagree with the idea that we can see in the text. First, she talked about the size of R. Robustus. According to the text, R. Robustus probably wasn't a hunter because it was to small. On the other hand, agreeable with the lecture, R. Robustus was more than twice bigger than baby psittacosaur - wich means that R. Robustus could easily hunt baby dinosaurs. After that, the professor pointed that the short legs of R. Robustus was not exactly a problem. She compared this dinosaurs with a Tasmanian devil. Besides the short legs of the Tasmanian devil, this animal is able to run about 90km/h. This means that as the Tasmanian devil can be fast also could be the R. Robustus. In the end of the lecture, the professor explained why the bones of the psittacosaur inside the R. Robustus stomach have had teeth marks. This fact can be explained because of the way that R. Robustus used to eat its prey - eating it whole or in smaller pieces.
