End of Oak Street movie Dinossaurs

So I just watched the movie The End of Oak Street, and it really really sucked…

I was wondering something, I’m a very Dinosaur-loving person, and this movie really sucked for me, but my main question is: if the plant at the beggining of the movie was from 200m years ago, then the movie should happen through the Triassic Age, then it shows a Stegosaur, and then an Allosaur, then a Spinosaur? I’d understand if I was watching Jurassic Park because there they are bringing them back, but in this movie, they go back 200M years ago…

Anyone else that shares my thoughts?
