Gallimimus is a genus of ornithomimid type theropod dinosaur that lived in what is now Mongolia during the Late Cretaceous period, about 70 million years ago. Key to the survival strategy of Gallimimus, and other ornithomimids, was speed. The legs especially the lower portions were long and capable of covering a lot of ground with each stride. The bones like in all theropods were hollow in order to reduce the overall weight of the body so that less energy was required to move and faster running speeds could be maintained. The main body however was proportionately longer than other related genera, and this may have had an impact upon how tight Gallimimus could turn. This may not have been so much of a hindrance however as much of Mongolia during the Cretaceous was open arid plain and realistically all Gallimimus would have to do to survive would be to outpace their potential predators. Like with all ornithomimids, there is no universal agreement upon what Gallimimus actually ate. The overall size of the skull is small in proportion to the body, but the snout is still longer than most other ornithomimids. The jaws were fashioned into a toothless keratinous beak, and without teeth of a certain kind, it is impossible to establish what Gallimimus ate without the evidence of stomach remains to give further clues. One thing that can be established is that the ‘beak’ could have been used to either pick out plant parts, or even pick up small animals. The size of the skull while small was still large enough to pick up small lizards, snakes and even mammals that realistically would have had to be swallowed whole since there were no teeth to process the bodies. Additionally the point of articulation in the jaws was so rigid that Gallimimus could do little more than open and close its mouth. If Gallimimus and other ornithomimids did indeed hunt small animals then they may have killed them by picking them up and throwing them hard against the ground in a similar way to how South American seriema birds do today (which are also seen to being analogous to the phorusrachid terror birds that lived after the dinosaurs). A final dietary option for Gallimimus would be to raid the nests of other dinosaurs for eggs.

Jurassic Park: Island Survival is the movie that take place in between Jurassic Park III, and Jurassic World. Isla Nublar, 2005. Approx. 120 miles off the coast of Costa Rica, 87 miles away from Isla Sorna. "There are several paleontologists missing on Isla Nublar. They had an expedition to explore and excavate the island for bone samples from several dinosaurs for extracting DNA sequences. The other important mission is to find the missing embryos from the Barbasol Cryogenics Can. On behalf of Simon Masrani, the science research team had to find out where those specimen are and check some important documents at the abandoned foliaged InGen Reseach Compound, which is decaying and overrun with vines deep in the dense afforestation now. Prof. Lytton and his research team have to survive the island for wildlife roaming the Restricted Area. Masrani Global Corporation sends special ops security forces to find them and bring them back home. The InGen Mercs and Asset Containment Unit try to handle the situation when there is an unexpected asset out of containment, causing havoc roaming the island."
