T. Rex Research and Pack Hunting

Those Jurassic Park/World movies took many liberties which included the speed of Tyrannosaurus rex and the increased size of the velociraptors. In their defense, the movies are money-making ventures to provide entertainment, not education. Also, new research on the critters came later. I have another rescuing device to offer.


Research on T. Rex indicates that they were not fast runners, and they may have hunted in packs. Some relevant evidence was ignored in the research.

When we go to movies, watch television, or even when reading novels, we have to suspend our disbelief and accept that reality. The dinosaurs in the Jurassic flicks were modified dinosaurs, so T. rex was fast and velociraptors not only taught their young, but were much larger than the turkey-sized versions that were fossilized. But that's just for fun and we have some interesting research to ponder.

Calculating body mass, bone density, comparison to living animals, and other factors, Tyrannosaurus rex was probably not entering foot races and jumping contests. A fall would probably be fatal, so it wouldn't be chasing after the other dinosaurs who taunted it by singing, "If you're happy and you know it, clap your hands..."

We recently saw questions raised about velociraptors and whether or not they hunted alone. T. rex is portrayed as a solitary hunter, but questions have been raised about whether or not they were also pack hunters because evolution. Since naturalists presuppose evolution and "pressures", evidence was interpreted in only one way, and fossils that were used in the research could be explained by the Genesis Flood. There is no evidence of dinosaur evolution (because they were created, not evolved), but the narrative of naturalism controls how evidence in interpreted.
Noting that slow-moving sauropods (a large herbivorous quadrupedal dinosaur) were rare in those communities where tyrannosaurs existed, with only a single taxon from North America known—and it lived in the southernmost portion of Tyrannosaurus’ range—the researchers believe that T. rex had to target faster prey like hadrosaurs (duck-billed dinosaurs) and ceratopsians (like Triceratops). Because hadrosaurs and ceratopsians are smaller and not as calorie-dense as sauropods, they reasoned that T. rex had “pressure for obtaining more kills due to the fact that each kill provides less resources, thus necessitating minimizing energy expenditure per hunt and maximizing resource extraction per kill, especially if that kill is shared amongst a group, [and which therefore] influenced selection for longer limbs in Tyrannosauridae.”
