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 fossil found of R.robustus and the stomach contained the remains of Psittacosaur dinosaur. The writer says that R.robustus was just a scavenger that sometimes fed on eggs of dinosaurs .The lecturer disagrees and believes that R.robutus is actively chased and hunted moving dinosaurs and attack each of the claims made in the reading.
First ,author says that size of R.robutus is small about a domestic cat and there is no chances of it hunting the two meter full grown psittacosaurs. The professor on the other hand believes that most predators hunted the prey which is twice the mass of the animals;R.robustus also hunted down baby dinosaurs and similiarly sized preys.
According to writer, the feature of legs i.e short and position of it more suited to tell that it did not chased prey ,as psiitacosaurs were fast moving mammals ,it is unlikely that they would have hunted down by short-leged mammals but speaker on the other hand points out with giving example of Tasmanian devil whose leg was also short in size but it's speed is upto 15km/hr and it was a success predator , so it is possible for ancient mammal to hunt with it short-leg .
The author also claims that there is no teeth mark found on the remains of bones psittacoasaus eaten by R.robustus : R.robustuss simply swallowed an egg of small pssitacoasur which is still inside the eggshell, the speaker refute this theory and says that R.robustus had powerful jaws and don't used their back teeth and swallowed whole prey or big pieces of it which shows no teeth mark on bones.
As you can see , the author and lecturer hold very different views on R.robustus.
