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. **

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. **

It is difficult to definitively say whether the Mosasaurus could defeat the T-Rex as they lived in different time periods and environments. The T-Rex was a land-dwelling dinosaur known for its strength and size, while the Mosasaurus was a marine reptile that lived in the oceans. In a hypothetical scenario where they were to face off, the T-Rex's powerful bite force and agility on land might give it an advantage, but the Mosasaurus' size, speed, and ability to swim could also make it a formidable opponent. Ultimately, it would depend on the specific circumstances of the encounter. **

Not all dinosaurs necessarily feared the T-Rex. While the T-Rex was one of the largest and most powerful predators of its time, there were other dinosaurs that were also formidable and may not have been afraid of the T-Rex. Some dinosaurs may have been able to defend themselves or escape from a T-Rex, depending on their size, speed, and defensive capabilities. Additionally, some dinosaurs may have lived in different habitats or had different behaviors that minimized their interactions with the T-Rex. **
