JOURNEY INTO TIME. 1960 Animated Classroom Film on Dinosaurs & Evolution. 

This was one of many classroom films a generation of kids sat through in science class.
The difference is that this this one is quite good. Some very nice period animation of dinosaurs and the earth formation. Please note that opening credits were missing from the original film, other that that it''s complete. This film fell into the public domain in 1988 from lack of copyright renewal.
