There sure were a lot of throwbacks to the original Jurassic Park in Jurassic World!
Here's a great video showing various direct visual allusions to Steven Spielberg's classic:
Jurassic World vs Jurassic Park Trilogy from whoispablo on Vimeo.
I loved how there were so many nods to the entire series, not just the first JP film. Like the Lost World (the Raptors herd running in the open wild, etc.) and Jurassic Park III (aside from the Spinosaur cameo, there were a few direct shots alluding to scenes like the "Raptors talking scene", the inner Dinos fight, the Pteranodon attacks and their giant dome, etc.). Yes, even though I don't like both the second and third film, I prefer they acknowledged them both as well unlike most people that were calling it a reboot.
