Dinosaurs are alive and well at the box office as Universal’s “Jurassic World Rebirth” trampled competitors, grossing $147 million domestically over five days of the Fourth of July weekend.

Dinosaurs are ruling the box office again. “Jurassic World Rebirth,” the seventh installment in Universal’s long-running prehistoric series, stomped to $147.3 million over its first five days in 4,308 North American theaters.

As Jurassic World movies tend to do, Rebirth features callbacks to a number of films in the franchise. However, it pays particular homage to the original—and greatest dinosaur movie to ever do it— Jurassic Park. Here are six of the best nods to Steven Spielberg's 1993 classic.
