In a cage match, T. rex has several adaptations that might give it an edge over Giganotosaurus. But don’t place your bets yet. The bigger dinosaur could leverage its skill at hunting massive sauropods to take down a smaller-than-usual foe. Narrator: It took a team of 20 sculptors to give the Giga its rough skin texture, with references ranging from historical evidence to crocodiles. Coria, Rodolfo A.; Salgado, Leonardo (June 1996).

David: We were kind of making a metal skeleton for the interior of the dinosaur to try and get as much believability and reality into the way it moved as possible. They’re not fighter jets,” she says. “You can’t say this one has this absolute top speed. They’re animals. And they’re animals that lived 30 million years apart on different continents. They’re separated by 150 million years of evolution [since their last shared ancestor].” But pitting the two against each other serves to highlight their differences, says Thomas Holtz, a principal lecturer in vertebrate paleontology at the University of Maryland who studies tyrannosaurs and their motion. This kind of thought experiment might lead to a better understanding of how these creatures followed their own evolutionary paths to become distinct, highly successful predators. In the past, Gigas used to gain rage from fall damage. However this mechanic has been removed. At the same time, changes were made to make rage buildup factor in raw damage as opposed to mitigated damage. This is to prevent high saddle quality from causing a Giga to not enrage since damage was minimal enough to prevent the mechanic from coming into effect. To set the skin, the foam needed to be baked into the mold, but the head was so large that it wouldn't even fit in John's oven. So instead of doing this step in one piece, they split it up into seven smaller sections, baking them in pieces in two ovens.

When the Giga closes its eye after Bryce Dallas Howard stuns it, the servos powering this eyeball and eyelid were preprogrammed as one movement. Paulina Carabajal, A.; Canale, J. I. (2010).

In 2021, the paleontologist Matías Reolid and colleagues compiled various mass estimates of theropods (including Giganotosaurus) to calculate the average, but did not include Therrien and Henderson's 2007 estimates of Carnotaurus and Giganotosaurus, considering them outliers. This resulted in a body mass range for Giganotosaurus between 5.5 and 8.5t (6.1 and 9.4 short tons), with an average of 6.75t (7.44 short tons). They also applied the skull length and body length ratio proposed by Therrien and Henderson and reconstructed various digital 3D models of theropods to measure body mass distribution and volume, resulting in the mass of a 13m (43ft) long Giganotosaurus up to 7.2t (7.9 short tons). These researchers found the estimates consistent with the values proposed by previous studies. [28] In 2022, Juan I. Canale and colleagues described the large carcharodontosaurid Meraxes, which has the most completely known Carcharodontosaurine skull, with an estimated length of 1.27m (4.2ft). Extrapolating from that skull, they estimated the skull of Giganotosaurus to have been 1.634m (5.36ft) long, making it one of the largest known theropod skulls. [29] Henderson suggested in 2023 that there was a close relation between the dimensions of the pelvic area and body size in theropods, allowing size estimates for incomplete specimens. Based on this idea, he found Giganotosaurus to have been 12.5m (41ft) long, identical to the estimate proposed in the 1995 description. [30] Description Size (green) compared to that of other large theropods Narrator: These precautions were just as important for the puppet's safety. Because it was built in pieces, the animatronic was incredibly fragile. That made some action-heavy scenes more suitable for CG, like this shot, where the Giga smashes its head through a giant window.
