The Allosaurus was a large dinosaur that lived during the Late Jurassic period, approximately 160 to 140 million years ago. It was a theropod dinosaur, in specific a carnivorous, bipedal predator.

Allosaurus was one of the largest theropod dinosaurs, with an average length of about 8 to 9 meters and weight 1.5 to 2 tonnes. Some individuals could grow even larger, reaching lengths of up to 12 meters and 5 tonnes.

It had a slender, agile body with strong hind limbs and shorter forelimbs. Its body was balanced by a long tail, which helped with stability and agility. Its head was large and its mouth counted with serrated teeth.

Allosaurus had three-fingered hands with sharp claws. While its arms were relatively short compared to its body size, they were still functional for grasping and manipulating prey.


It is believed that Allosaurus may have been both solitary hunters and social animals, with evidence suggesting that they may have hunted in groups or scavenged together at times. Allosaurus was an apex predator of its time, preying on herbivorous dinosaurs like sauropods and stegosaurs. It likely used its speed and agility to pursue and capture prey.

After tranquility

Although several semi-successful attempts at lazurogenesis were made during the Interplanetary Age by organizations like Dinoworld and Jurassic Enterprises, the creatures' large size and aggressive nature made them difficult to keep. In addition, the artificial conditions and enclosed pens meant they suffered a high mortality rate through stress-related ailments. The creatures were not successful reconstructed in their original habitat until the Jurassica Institute of Lazurogenetics established a viable breeding colony on Owen, where the largest population is still to be found today.

During the Age of Separate Empires, the hyperturing GEvidian provolved a number of wild Allosaurs. While a few Allosaurus sapiens live even today in several of the large orbital habitats around Owen, others accompanied GEvidan and the Dino Kids, purportedly to Ruprect 108, although the ultimate destination was never known.

Heavily derived Allosaurii (Allosaurus cosmoi, Allosaurus spatialis) bearing GEvidan's characteristic signature can occasionally be seen in their giant relativistic and trader ships throughout much of the outer Hinteregion polities.
