Because, even looking at the bones, you can not know when it was born because there were no records or anything.
As far as my research has led me, I can only conclude that Allosaurus evolved into Tyrannosaurus.
Allosaurus was the largest predator in its habitat, so the only formidable enemy of an adult Allosaurus would be another adult Allosaurus. For young Allosaurus, however, threats included Torvosaurus and Ceratosaurus, and even larger Allosaurus.
Yes, Allosaurus only ate meat, and thus was carnivorous. Allosaurus probably hunted large, herbivorous dinosaurs such as Camptosaurus, Dryosaurus, and Stegosaurus, and young sauropods. If they hunted in packs on occasion, they may have even hunted huge adult sauropods such as Diplodocus, Brachiosaurus, Camarasaurus, and Apatosaurus.
"An average Allosaurus had a lifespan of about 25 years." However, that isn't entirely accurate. Only a very lucky few Allosaurus lived the full length of their 28 year lifespan. More accurately, you would say that the maximum lifespan of Allosaurus was 28 years.
I've found one estimate of the absolute magnitude of Mira: 0.93. However, Mira is a variable star, so perhaps that's an average value. Also, the distance to Mira is not known precisely, so any value for absolute magnitude can only be approximate.
It is unknown whether Allosaurus hunted prey animals far larger than itself, such as adult sauropods. If it did, it is believed that Allosaurus would have mobbed the prey animals and slashed them, causing them to eventually bleed to death. However, it may have only hunted young sauropods and other herbivorous dinosaurs such as Camptosaurus, Dryosaurus, and Stegosaurus, and simply scavenged on adult sauropods. To hunt these dinosaurs, Allosaurus probably would have hunted alone by ambushing them, then chasing them at a top speed of between 19 and 34 miles per hour. When Allosaurus caught up, it would grasp the prey with its hands and then dispatched it with bites to the throat.

Okey. I'll try to make Allosaurus sound very cool. -Allosaurus was 37 feet long, 14 feet tall and weighed 2-5 tons. -It lived 155-144 Mya, in North America. -Although smaller than Tyrannosaurus, Allosaurus may have been the most lethal carnivore on the planet. -Allosaurus could take on any prey item at it's time, like Camarasaurus, Stegosaurus or Camptosaurus. -Allosaurus was the largest carnivore in the movie '' The Lost World. " - The only thing brave enough to take on Allosaurus is a 24 ft long predator named Ceratosaurus. - Allosaurus was found in 1877, and it's name ment '' Different lizard".
Dinosaur weight is highly debatable, but most scientists estimate between two and three tons, with some experts postulating almost four or four and a half tons.
Young Allosaurus were either protected by their parents or simply ran to escape danger. Adult Allosaurus were 28 feet long and weighed somewhere between 2,200 and 8,800 lb depending on whose estimate you use. Because they were the largest predators in their habitat, the only significant threat to adult Allosaurus were other adult Allosaurus. They would have fought each other mostly by biting, but they may have also used their relatively strong arms and struck each other with their claws.
