Among the intriguing mysteries that the dinosaurs have left for us, one of the most persistent is what the arms of Tyrannosaurus Rex (T.rex) were used for. A recent presentation to the American Geological Society presented evidence to support the idea that the arms were well-adapted for slashing attacks on T. rex's prey.

Firstly there is evidence related to the structure of the arms. The arms of T. rex appeared to be so tiny and weak compared to the rest of its body that early researchers dismissed them as being virtually useless. But recent analysis of marks on the fossilized bones of T. rex arms show that they were connected by significant amounts of muscle tissue: enough to lift or push nearly 400 kilograms. They would have had plenty of power to slash.

Secondly, the claws of T. rex show an unusual feature which would have made them very well-suited to slashing. Each arm has only two claws, as opposed to the three claws that are normal on smaller carnivorous dinosaurs. The reduced number of claws means that the power of the arm would be focused onto just two points, resulting in deeper cuts. And the curved claws themselves were 6 to 10 centimeters long, similar in size to the teeth of T. rex.

Thirdly, the length of the arms makes sense in terms of efficiency. The arms could have provided T. rex with the means to slash at prey held in its jaws. With the jaws holding the prey close, the arms would have been able to tear gashes over a meter long and several centimeters deep in just a few seconds. Longer or heavier arms might have done the job better, but they would have weighed more and cost T. rex too much energy to carry around.

Both the reading and lecture discuss the mystry behind the Tyrannosaurus Rex (T.rex) arms whether it uses them for prey or not. Former states three point to indicate well-adaptation of arms for prey and latter counters the merits of the points by explaining them insignificant.

First of all, author of the reading claims that T.rex arms were well connected with muscle tissue which would enough to carry up upto 400 kilograms and giving the T.rex capabilites to slash for prey. The lecturer agrues this by saying that arms primary purposes are not for slashing for prey rather the fossils of the T.rex shows significant fractures in bones. As a result, using arms for prey would lead them to death.

Secondly, the author states that T.rex would have tow claws instead of three. For that, It could exert more power for slashing for prey. The lecturer counters this and claims this as irrelevant. He points out that the teeths and it's poweful bites were enoungh to prey for T.rex.

Finally, the reading says that length of the arms provides power T.rex for slashing power for prey .However, The lecturer agrees this for young T.rex and claims it's not the case for adults. Because,adults jaws are enough to prey and long arms are not required for prey.
