For the purpose of relevancy, I'm only including films with species related to the Mesozoic and, to a extent, the Paleozoic eras. So no films like
10,000 B.C.,
The Meg, or
Walking with Beasts are included.
With Nessie/Loch Ness Monster, I'm only counting films with references to a prehistoric species, so ones like
The Water Horse, which uses a mythical basis for the creature, are not included. Likewise, films with dragons are not counted.
Fantastic dinosaurs need to have some reference to prehistoric origins or dinosaur characteristics (besides some versions of Godzilla which are being included for completion reasons).
We don't mention Barney here.
