Final answer:
The 1993 movie featuring a hatching dinosaur is 'Jurassic Park.' Although titled after the Jurassic Period, many of the dinosaurs depicted in the film lived in the Cretaceous Period, a testament to Hollywood's creative liberties.
Step-by-step explanation:
The hatching dinosaur shown in the 1993 movie trailer is from Jurassic Park. The movie, directed by Steven Spielberg, featured a fictional theme park with cloned dinosaurs.The term Jurassic is derived from the Jurassic Period, a geologic time span that lasted from 201.3 million years ago to 145 million years ago.
Dinosaurs were a diverse group of animals that became the most significant land vertebrates during the Mesozoic Era, known as the Age of Dinosaurs. While the Jurassic Period was a time where dinosaurs flourished, it's important to note that dinosaurs spanned a longer timeframe beyond just the Jurassic, thriving until a catastrophic event led to their extinction and ultimately allowing mammals to take over.
