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.
The reading passage states three reasons for why robustus was not hunters, but it was just a scavenger that fed on dinosaur eggs.
First, as the reading passages says that robustus had a small size which was not suitable for hunting such a big size such as psittacosaura or dinosaurs. However, the speaker denies the passage's statement by pointing out that robustus was really small in size, but they were bigger than baby dinosaurs. Therefore, this supports that robustus could be a hunter not scavengers.
Second, the writer says that robustus were scavengers because they had short-sided legs, which were not suitable for chasing and catching such a super fast prey like psittacosaur. Yet, the lecturer refutes the passage by arguing that there is a modern animal has the same sided-short legs and can chase his prey as his speed reach 50 km/hr. Thus, based on the similarities between robustus and the modern animal, robustus were hunter to dinosuars.
Third, the reading passage claims that because there are no teeth marks in the prey bones, this indicates that robustus didn't hunt the prey, but he just found unsave nest with small psittacosaur and swallowed them. On the other hand, the professors opposes that by mentioning that robustus didn't use his teeth to catch the prey, instead he swallwed the whole prey or ate it in big pieces.
