Spinosaurus was a genus of large theropod dinosaur which lived during the Cretaceous period.

At a length of 17 metres and a weight of 11 tonnes, it was the largest terrestrial predator of all time.

Lost World

A Spinosaurus spooks a herd of Ouranosaurus which mistake it as a threat.  The Spinosaurus, fortunately, is not interested in the dinosaurs as they are not its usual prey.

The Spinosaurus arrived at a river and scared off some crocodiles. The reason why the Spinosaurus came to the river was to feed on sawfish called Onchopristis.  The Spinosaurus went into the river and waited for the Onchopristis to come close. It was able to snatch one out of the water and kill it on the river bank where it fed on the fleshier parts of the carcass. This was wasteful, letting a smaller Rugops to scavenge on the remains.  It returned to river and killed another Onchopristis and ate that one too. Later, it swam down the river.

During a drought, a Spinosaurus confronted a small crocodile but was then repelled by a Sarcosuchus which was disturbed during its hibernation. The spinosaurus was at great risk of being dragged in by the 40 foot sarcosuchus, where in this case, the spinosaurus was full aware and had been forced to move on. It later attacked a feeding flock of the pterosaur Alanqa, killing one in the process.  It then moved on due to its hunger.

It later came across a Carcharodontosaurus feeding on a Ouranosaurus carcass. The Spinosaurus confronted it and the two predators fought over the carcass. The Carcharodontosaurus managed to bite the Spinosaurus' sail during the battle. The Spinosaurus won the fight and fed well however, its sail was broken by the bites. These injuries were fatal and the Spinosaurus died days later.


  • Spinosaurus is the largest theropod dinosaur in the show.
  • Alongside Rugops, Spinosaurus is the only African species that didn't appear in the fifth episode, New Giants, as well as Lost World.


  • In 2014, Spinosaurus was discovered to have a sail that was different from how this program showed.
  • The Spinosaurus, according to the 2014 article, had shorter back legs than previously thought & how this program showed it.
  • The shorter back legs (and the already known 'crocodilian' snout) suggest that Spinosaurus could swim. This feature however has clearly shown in the episode of the Lost world; lately the capability of swimming spinosaurus is on doubt however.
  • Spinosaurus theorized to be capable of walking on all fours, according to the 2014 speculations, although it was later debunked.
  • Latest 2018 research shows that the Spinosaurus did not have the ability to swim well; and most likely spent most of its time on land and/or shallow water; this has shown in the program accurately.
  • In 2020, a research suggested that the tail of Spinosaurus was paddle-like, and this; considered as, that it had the ability to swim, however several paleontologists have counter thesis against that conlusion; but it was bipedal.
  • In 2021 a new research has indicated that the degree of aquatic attributions for Spinosaurus is not consistent. Spinosaurus was most likely a terrestrial generalist carnivorous theropod that wade through the waterways and shores; akin to herons, pelicans, shoebills, giant petrels and skuas.
