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 article introduces the topic of the million-year-old mammal known as R. robustus. More specifically, the writer discusses about the mammal and its behaviour that might be true. However, the lecturer disagrees to the writer.
In the reading, the author introduces that R. robustus was not an active hunter; rather, it was a scavenger. Nevertheless, the lecturer disagrees stating that they were actually hunter and they haunted small sized dinosaur and their babies. Also, she continues by stating that the body of the R. robustus was 72 times larger than the dinosaur found in its body.
The author also claims that the size of R. robustus was so small that it did not haunt dinosaur. But, the lecturer rebuts by stating that the similar size tasmania devil can run fast and haunts on several animals; so, this case also applies on the mammal on discussion.
Furthermore, the passage also claims that there were no evidence of the tooth marks on the dinasaur in body of mammal to support that the R. robustus were hunters. However, the lecturer refutes by mentioning that robustus actually swalloed the whole without chewing, although, they had sharp teeth. She continues saying that they did not use their sharp jaws while chewing; as a result there were no marks of teeth in the body of the dinosaur found in the stomach of R. robustus.
To sum up, both the writer and the lecturer have conflicting viewpoints about the eating behaviour of the R. robustus.Therefore, it is clear that they will have trouble finding common grounds on this issue.
