I was just watching a trailer for the new Jurassic movie and was thinking to myself that the special effects industry really has grown since the old Godzilla movies. But I'm sure at the time that it was a good special effects. It got me wondering about times earlier than that. Which leads to my question, What is the first movie/show that introduced dinosaurs as a "real" creature? As in, not a cartoon, but ones interacting with a set. I think it would be fun to watch and compare.
The first movie dinosaur was a cartoon, Gertie the Dinosaur, in 1914.

The Sid & Marty Kroft series "Land of the Lost" from the mid/late 70s had moving dinosaurs. One smaller dino named Dopey got close enough to be touched. The dinosaurs were some form of model, obviously and added in post production.
The Last Dinosaur was a 1977 film about the present-day discovery of an isolated valley where a few dinosaurs still live. The film features a Tyrannosaurus Rex, a Triceratops, a third creature which isn't actually a dinosaur, and Richard Boone as Maston Thrust, a wealthy industrialist and big game hunter.
The film was a joint production of Rankin/Bass and Tsuburaya Productions, the Japanese company that produced shows like Ultraman. The dinosaur scenes were filmed using the "man in suit" method, like the Godzilla films of the time. A man-sized Dinosaur prop, with a man inside providing movement, was filmed on a scale model set.
The movie was apparently intended as a theatrical release, but it eventually ran as a TV movie on the USA network.
The trailer is on youtube:
Searching for the movie title will turn up other clips.
I'm pretty sure it was the first Jurassic Park. All of the dinosaurs on there were animatronic but they all look and act realistic.
