Indominus Rex is faster than T-Rex. Indominus Rex is portrayed as a genetically modified hybrid dinosaur with enhanced speed and agility, making it faster than the traditional T-Rex. This difference in speed is often highlighted in the Jurassic Park franchise, where Indominus Rex is shown to be more agile and quicker in its movements compared to the T-Rex. **

No, 5 tigers would not be able to defeat a T-Rex if it were still alive. T-Rex was a massive and powerful predator, estimated to weigh up to 9 tons and measuring up to 40 feet in length. Its size, strength, and sharp teeth and claws would make it nearly impossible for 5 tigers to overpower it in a fight. **

Yes, the T-Rex, short for Tyrannosaurus Rex, was a real dinosaur that lived during the Late Cretaceous period, around 68-66 million years ago. Fossils of the T-Rex have been found in North America, particularly in states like Montana, South Dakota, and Wyoming. It was one of the largest carnivorous dinosaurs, known for its massive size, powerful jaws, and sharp teeth. **

There have been several movies featuring T-Rex, including the iconic "Jurassic Park" series, which includes "Jurassic Park" (1993), "The Lost World: Jurassic Park" (1997), "Jurassic Park III" (2001), and the more recent "Jurassic World" (2015) and "Jurassic World: Fallen Kingdom" (2018). Additionally, there are other films that feature T-Rex, such as "The Land Before Time" (1988) and "The Good Dinosaur" (2015). T-Rex has also made appearances in various other dinosaur-themed movies and documentaries. **

There is ongoing debate among scientists about whether the T-Rex was primarily a scavenger or an active predator. Some evidence suggests that its powerful jaws and sharp teeth were well-suited for hunting and killing live prey. However, other research points to the T-Rex having a keen sense of smell, which could have been used to locate and scavenge carcasses. Ultimately, the exact feeding behavior of the T-Rex remains uncertain, and it is possible that it may have engaged in both scavenging and hunting. **

There is currently no definitive evidence to suggest that T-Rex hunted in packs. Fossil evidence indicates that they were solitary hunters, relying on their size, strength, and speed to catch prey. However, some scientists believe that T-Rex may have exhibited some pack behavior, similar to modern-day crocodiles, where individuals may have occasionally cooperated during hunting or scavenging. More research is needed to determine the social behavior of T-Rex with certainty. **

Despite their small size in comparison to their massive bodies, the T-Rex's arms likely served a purpose in their evolutionary history. Some theories suggest that they may have been used for grasping onto mates during mating rituals, holding onto prey while feeding, or even for balance while standing up. While their arms may not have been as functional as their powerful jaws and legs, they still played a role in the T-Rex's survival and behavior. **

T-Rexes are believed to have lived to be around 20 to 30 years old in the wild. However, some researchers suggest that they could have lived up to 30 to 40 years old. Their lifespan was influenced by factors such as injuries, diseases, and competition for resources. **
