Wanna make a Jurassic Park parody called Cambrian Aquarium where it’s just the exact same plot but instead of dinosaurs it’s a bunch of marine invertebrates from the Cambrian
I want to point out that they don’t kill people. Instead you get scenes like:
“Sir, the security systems are all shutting down!”
[cut to a shot of a bunch of trilobites scuttling around on the floor]
Maybe the tension in the movie can come from them being an invasive species?
There was a tv show about going back in time and wrangling ancient animals.
All I remember is a british man picking up a eurypterid.
You’re thinking of Sea Monsters: A Walking with Dinosaurs Trilogy. Starring Nigel Marvin, the worlds worst time traveler. (http://www.kisamayatsu.com/video/nigel/)
Thanks! It’s a definite rewatch
