Dinosaurs rule this Fourth of July holiday weekend, but will they keep the crown when DC and Marvel enter the race later this month with some superpowered challengers?

The latest reboot of the killer dino franchise, starring Scarlett Johansson, collected a toothy $147 million in the U.S. and Canada.

Rebirth - the latest instalment in the blockbuster dinosaur saga - stomped the July 4th weekend competition at the North American box office, raking in a whopping US$91.5 million in its debut, industry estimates showed on Sunday.
