Archaeologists have recently found a fossil of a 150-million-year-old mammal
known as Repenornamus 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 psittacosaur
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.
Both the reading passage and the lecture are discussing whether R. robutus was a hunter or not. The reading claims that the R. robustus couldn’t be a hunter and gives three reasons in support. Whereas, the lecture counters all three points made in the reading passage in favor of R. robustus not being a hunter.
Firstly, the passage maintains that R. robustus was too small to be a hunter. They were much smaller in size than their supposed prey. The lecture counters this point by claiming that though R. roubstus was smaller in size than full grown dinosaurs, they were bigger than baby dinosaurs. In fact, the lecture claims that R. robustus’ body mass was more than twice than that of baby dinosaurs. So, R. robustus could very well be hunters of the baby dinosaurs 150 million years ago.
Secondly, the reading claims that the legs of R. robustus matches more with scavengers than with hunters. Their legs were smaller and also positioned sideways. From this, the reading concluded that R. robustus could not have been hunters The lecture provides an example to contradict this claim. Tasmanian devils, well-known hunters, had similar legs as R. robustus. So, neither smaller size nor sideway positioning of legs could stop R. robustus from hunting.
Finally, the reading says that as there were no bite marks on the bones of the dinosaurs found inside R. robustus’ stomach, it is more likely that R. robustus ate dinosaurs’ eggs rather than hunting down full grown dinosaurs. On the other hand, the lecture claims that R. robustus used to swallow their meals in big pieces as there were little to no wear in their back teeth. So, even if the dinosaurs found inside the stomach of R. robustus were hunted down there wouldn’t have been any bite mark on the bones of the dinosaurs.
