Archaeologists have recently found a fossil of a 150-million-year-old mam-mal known as Repenomomus robustus (R. robustus). Interestingly, the mammal's stomach contained the remains of a psittacosaur dinosaur. Some researchers have therefore suggested that R. robustus was an active hunter of dinosaurs. However, a closer analysis has made the hypothesis that R. robustus was an active hunter unlikely. It was probably Just a scavenger that sometimes fed on dinosaur eggs containing unhatched dinosaurs.
First, R. robustus, like most mammals living 150 million years ago, was small—only about the size of a domestic cat. It was much smaller than psittacosaurs, which were almost two meters tall when full grown. Given this size difference, it is unlikely that R. robustus would have been able to successfully hunt psittacosaurs or similar dinosaurs.
Second, the legs of R. robustus appear much more suited for scavenging than hunting: they were short and positioned somewhat to the side rather than directly underneath the animal. These features suggest that R. robustus did not chase after prey. Psittacosaurs—the type of dinosaur found in the stomach of R. robustus—were fast moving. It is unlikely that they would have been caught by such short-legged animals.
Third, the dinosaur bones inside the stomach of the R. robustus provide no evidence to support the idea that the dinosaur had been actively hunted. When an animal has been hunted and eaten by another animal, there are usually teeth marks on the bones of the animal that was eaten. But the bones of the psittaco-saur inside the R. robustus stomach do not have teeth marks. This suggests that R. robustus found an unguarded dinosaur nest with eggs and simply swallowed an egg with the small psittacosaur still inside the eggshell.
The article states that R. robustus was a scavenger rather than a active hunter and provide three reasons for support. however, the professor explains that R.robustus was an active and successful hunter and refutes each of the author's reasons.
First, the reading claims that R. robustus was small, similar to the size of a domestic cat, whereas the psittacosaurs were almost two meters tall when full-grown. Hence it is unlikely that R.robustus would have been able to successfully hunt pittacosaurs or similar dinosaurs. but the professor refutes this point by saying that R.robustus was much bigger than baby pittacosaurs and that is why it is much likely that R.robustus hunt these small baby dinosaurs. also record suggests that the mass of a full-grown R.robustus was twice the mass of a baby pittacosaur or similar dinosaur giving the evidence that R.robustus was really a predator.
Second, the article posits that the legs of R.robustus were short and positioned somewhat to the side which was much more suited for scavenging not for hunting. however, the professor says that the length and position of the legs of R.robustus were similar to that of Tasmanian Devil, which is known to be an active and successful hunter. this suggests that R.robustus can also be a hunter.
Third, the reading says that there was no teeth mark on the bones of the pittacosaur that was eaten by R.roubustus. this suggests that R.robustus found an unguarded dinosaur nest with eggs and simply swallowed an egg along with the small pittacosaur, suggesting that R.robustus was a scavenger rather than a hunter. but the professor opposes this point by explaining that though R.robustus has strong jaws we haven't found any teeth mark on the bones of its prey because it simply swallowed it.
