Dinosaurs Alive features over 40 life-sized animatronic dinosaurs, which are scientifically accurate based on the latest paleontological knowledge. These fascinating specimens were created by the Canadian-based company, Dinosaurs Unearthed. Launched, in 2005, Dinosaurs Unearthed is an innovative traveling exhibition company that creates dynamic, multi-sensory experiences about the fascinating world of dinosaur discovery.




Name: Albertosaurus
(al-BER-tuh-SOR-us)

Size Length: 30ft/9.1m
Height: 15ft/4.6m
Weight: 6,000lbs/2,727kg



In the deltas and floodplains of the Horseshoe Canyon Formation of the Western Interior Seaway, Albertosaurus was the apex predator of its time.

Perhaps as evidence of pack-hunting, 22 Albertosaurus individuals ranging from six juveniles between the ages of 2 and 11 years of age, seven sub-adults between 12 and 16, eight adults between 17 and 23 and one very old adult estimated to be 28 years of age were found in one location. It has been theorized that the juveniles and adults occupied different niches on the feeding chain and that the fleeter footed juveniles and sub-adults may have driven prey towards the slower, but more powerful, adults.



Name: Baryonyx
(BEAR-ee-ON-ix)

Size Length: 30ft/9.1m
Height: 8ft/2.4m
Weight: 4,000lb/1,818kg



Plunging into the river in pursuit of food, much like a modern grizzly bear, Baryonyx used its 12” curved, hooked-like claw on its largest digit, or finger, to catch a fish before 96 teeth clamped down on the hapless victim. Or did it hunt stealthily from the bank like a heron or egret do today? Scientists hold differing views but either way we do know that Baryonyx was one of the few fishermen of the dinosaur world.



Name: Ruyangosaurus
(Roo-YAHNG-o-SOR-us)

Size Length: Over 99ft/30.1m
Height: Over 30ft/9.1m
Weight: Over 85 tons



Unearthed in 2007 and described in 2009, Ruyangosaurus replaced Huanghetitan (found in the same location in 2006) as the largest Cretaceous sauropod yet discovered in Asia.

A sauropod of the titanosaur group, Ruyangosaurus had a shorter neck and tail than earlier Jurassic sauropods like Omeisaurus and Mamenchisaurus. The broader chest and slimmer hip area meant that titanosaurs like Ruyangosaurus presented a much different physical appearance than earlier sauropods. The flexible spinal column also meant that the dinosaur could possibly rear on its hindlimbs. Like many titanosaurs, the skin of Ruyangosaurus was armoured – covered in small bead-like scales.



Name: Stegosaurus
(Steg –oh- SOR- us)

Size Length: 30ft/9.1m
Height: 14ft/4.3m
Weight: 15,000lb/6,818kg



Trackways of Stegosaurus show that it was a herd animal with all ages of animals living together. This herd mentality would have offered protection from predators to the vulnerable, smaller juveniles. While a juvenile Stegosaurus possessed all the same physical features of an adult in a smaller scale, it is not possible that it would have been able to defend itself from Allosaurus, the apex predator of its time.

The tail spikes of Stegosaurus were certainly used for defence against Allosaurus! Fossil evidence shows a punctured Allosaurus tail vertebra into which a Stegosaurus tail spike fitted perfectly.




Name: Triceratops
(try-SER-uh-TOPS)

Size Length: 25-30ft/7.6 - 9.1m
Height: 10ft/3m
Weight: 22,000lb/10,000kg


Triceratops was no gentle, plant-eating giant. Many fossil records show damage to Triceratops bones which could have occurred in combat with other Triceratops or predators. The horns of a Triceratops could be used as weapons, as displays of domination to other Triceratops, or as mating displays. The neck frill would have offered some protection against the bite of the Tyrannosaurus rex and perhaps would have regulated body temperature.



Name: Tyrannosaurus Rex
(tuh-RAN-uh-SOR-us)

Size Length: Over 40ft/12.2m
Height: 13ft/4m (at the hips)
Weight: 14,000lb/6,363.6kg



As the last great carnivore of the Cretaceous Period, Tyrannosaurus rex was an efficient killing machine stalking the North American landscape. With a specially strengthened nose structure that enabled it to deliver bone splintering, crushing bites to both captured prey and during combat with others of its species, a Tyrannosaurus rex lower jaw could deliver 10,000 newtons of force – the equivalent of being able to lift a semi-trailer.
