Spinosaurus

An aggressive and agile predator capable of taking on a Tyrannosaurus rex is largely an idealization of popular culture and does not reflect current science. Recent studies indicate that it was more of an aquatic generalist, with a more elongated body adapted for swimming and fishing, rather than a ferocious terrestrial fighter.
Personality in cinema and games
Aggressive and fierce:
In productions like Jurassic Park 3, the Spinosaurus is presented as a super predator, agile and determined, that overcomes a Tyrannosaurus Rex in confrontation.
Skilled in swimming:
Its swimming ability is highlighted, with the sail serving as a fin to aid swimming.
Personality based on scientific research
Aquatic generalist:
The most recent research indicates that Spinosaurus was a semiaquatic predator, better adapted to hunting in aquatic environments such as rivers and mangroves.
Adaptations for water:
Fossils show adaptations for the aquatic environment, such as dense leg bones and a body better adapted for swimming, but debate over the ability to swim actively continues.
Social behavior:
In games, spinosauruses display head gestures and interact socially, suggesting that the display of sail patterns was a form of communication and identification between them.
It wasn't as aggressive on land:
The idea that he was an agile and ferocious land fighter, who confronted Tyrannosaurus, is questioned by science, being a representation more linked to popular culture than to scientific reality.
