This hadrosaur (duck-billed dinosaur) has appeared in every film in the franchise so far, including this latest instalment. Parasaurolophus, with its recognizable crest, can be seen in several scenes, fleeing from volcanoes or predators or struggling to escape its enclosure.
Parasaurolophus was a herbivore that existed during the Late Cretaceous period, roughly 75 million years ago. There are several hypotheses regarding the function of the dinosaur's crest, ranging from sound amplification to use as a sort of snorkel. Very little is known about Parasaurolophus, but it is generally accepted that-- like other hadrosaurs-- it could walk on both four legs and two. Experts also generally postulate that the dinosaur travelled in herds, just like they do in Jurassic Park.
As we've seen it do in almost every Jurassic Park film, the Gallimimus appears in Fallen Kingdom running at breakneck speeds away from both predators and a major cataclysmic event. It too escapes at the end of the film and can be seen fleeing into the woods, free to race across the continent alongside other peaceful dinosaurs.
Gallimimus is believed to have been among the fastest dinosaurs. With its powerful legs, it is estimated to have reached speeds of up to 50km/p. Its large eyes also suggest that it was a nocturnal creature and experts believe that it's entirely possible that Gallimimus could have been an omnivorous creature, feeding on both plants and small animals. It grew to about 20ft in length and grew to about 6ft at the hip. It existed around 70 million years ago, during the Late Cretaceous period.
These little lizards have appeared before, famously feasting on a little girl on Isla Sorna in The Lost World: Jurassic Park (directed by Steven Spielberg). They return in Fallen Kingdom but are small enough in the film that you'd be forgiven for missing them completely. You might have caught a glimpse of one rushing past Franklin during the chaotic stampede on Isla Nublar and you may have seen it again during the final escape from the Lockwood estate.
Compsognathus, just as it is in the film, was tiny. It was estimated to have been about 3ft in length and just 10 inches tall at the hip. For a long time, it was thought to have been the smallest dinosaur, before the discovery of others such as Microraptor. Compsognathus was a carnivorous therapod that existed during the Late Jurassic period, 150 million years ago.
