Species Profile - Spinosaurus

I know this dinosaur... it’s a Spinosaurus. So named because of the spines running down its back. Seriously, who needs a PhD for this one?

Spinosaurus is a large genus of spinosaurid dinosaur that originated in Early Cretaceous Africa. Spinosaurus is first encountered as a wild animal on Isla Sorna, and can subsequently be bred by extracting its DNA from fossils discovered in the Chenini and Bahariya Formations.


After the San Diego Incident in 1997, which brought the existence of dinosaurs on Isla Sorna to public knowledge, the failing InGen, which had all but collapsed in the wake of the disaster, was purchased by Masrani Global.[1] Only one hundred days after the deal was finalized, and in violation of the Gene Guard Act, which banned access to Isla Sorna and the cloning of prehistoric species, an InGen team incubated several new species of dinosaur, including Ankylosaurus, Ceratosaurus, Corythosaurus and, most notably, Spinosaurus.[1]

Bred covertly in 1999 under hybrid "Amalgam Testing", which paved the way for genetically modified creations such as the Indominus rex, the Spinosaurus was experimented on over a period of nine months before being abandoned on the island.[1][2]

Spino versus Rex

A Spinosaurus faces off against a Tyrannosaurus.

In 2001, the only Spinosaurus known to have been cloned by InGen was encountered on numerous occasions by the survivors of a plane crash on Isla Sorna and was responsible for the deaths of numerous individuals, as well as a Tyrannosaurus which had entered its territory.[3] Reports of the Spinosaurus was later reported to the authorities by the survivors, but it was covered up by "bribed officials" and went undisclosed until 2015.[1]

The introduction of the Spinosaurus, and to a lesser extent the other illegal species, had a profound impact on the ecosystem of Isla Sorna, resulting in a considerable population drop which mystified the scientific community until 2015. In 2004, the surviving dinosaurs on Sorna were transported to Jurassic World on Isla Nublar, though it remains unconfirmed if the Spinosaurus was among them.[1] Regardless, in 2018, the animal was reported as extinct.[4]

Heavily built and fearsome, the base genome of the Spinosaurus is primarily grey with distinctive patterns of red across the body, and blue circular patterns across its impressive sail. As a large and territorial predator, Spinosaurus has been known to challenge similarly sized carnivores such as Tyrannosaurus, and can effortlessly lift a hadrosaur, such as Maiasaura, off its feet with its jaws and slam it into the ground.[5]

Paleontology Edit

Spinosaurus remains have been found in Egypt, Tunisia, and Morocco. The first remains were found in Egypt by a German palaeontological team led by Ernst Stromer in 1915 and brought to a museum in Munich. Other fossils found were those of a small sauropod Aegyptosaurus, a myriad of crocodiles and fish and another massive carnivore, the fearsome Carcharodontosaurus. Unfortunately, these fossils were destroyed during a bombing raid in World War II. Since then, Spinosaurus was referenced in books as a moderately sized dinosaur with a sail and the posture of a generic theropod, but was overshadowed by the likes of Tyrannosaurus and Allosaurus.

In the 1990s, with new discoveries in Tunisia and Morocco, it was revealed not only the crocodile-like snout shared by all known spinosaurids, but the sheer size of the animal, among the largest theropods ever found. From the 1990s to the early 2010s, Spinosaurus was shown as a massive bipedal super predator, hunting anything it wished and challenging other large carnivores. However, subsequent discoveries overshadowed this depiction of the animal, and Spinosaurus was reconstructed as a quadrupedal fish eater, which could occasionally rear on its hind legs. While the quadrupedal movement has since been disproven, the narrow jaws weren't suitable for tangling with large prey and so it had to catch fish; however, evidence suggests spinosaurids did hunt terrestrial prey as well.

The sail of Spinosaurus has also been a point of discussion, like that of Ouranosaurus from Niger, with some claiming it is a large sail for display or thermoregulation like Dimetrodon, and others arguing it is a fatty hump like that of a camel for dry periods.


  • Spinosaurus was the seventeenth dinosaur to receive a Species Profile.
  • The appearance of the Spinosaurus in Jurassic World Evolution is directly based on the animal's depiction in Jurassic Park III, although the colours of its sail are more distinctive. The scaling of the creature differs from its film counterpart, which was marginally larger than the Tyrannosaurus. In-game, the Spinosaurus is noticeably smaller than the T. rex. In response to community feedback, the size of the Spinosaurus will be increased from 13.7 metres to 15 metres in a future game update.[6]
  • Spinosaurus previously appeared in Jurassic Park: Operation Genesis, considered by many to be Jurassic World Evolution's spiritual predecessor.
  • According to recent reconstructions, Spinosaurus had a single crest on top of its head, shorter legs, an M-shaped sail, and was likely semi-aquatic.[7]
  • The only species of Spinosaurus was S. aegyptiacus. However, a potential second species was uncovered in Morocco in 1996, called S. moroccanus.
  • Like with Torosaurus, there is a slight dating error in the InGen file for Spinosaurus where the date of discovery is said to be 1922 rather than 1912.
