Does not appear to mention "the land that time forgot" (1974) with the inimitable Doug McClure, not his eponymous cartoon alternate Troy, who we all remember from his fine educational films such as "Dinosaurs: not a good addition to a shaving Foam cannister"

The screenplay was Michael Moorcock, the original is Edgar Rice Burroughs 1918. I watched this at least 3 times in a tiny one-man cinema (Jaggers) in pembroke on holiday

It's craptacular, but I loved it as a smallish child. Has everything: submarines, forgotten land, buxom heroine, grenades..

Stephen Baxter, Evolution (2002) hypothesises social intelligent carnivore Dinosaurs herding herbivores, but since they use only organics to make their whips and tools, no remains exist in deep time. Would make a whimsical film, if not a good one.

Raquel Welsh stared in one (1 million years bc, 1965) which is mostly memorable for her fur bikini. They had some scaling issues with their anachronistic creatures too. Typical Hollywood: it's a remake of one from the 1940s.

The best Dinosaur movie is the quest for fire (1981) which doesn't have any because it's about Neanderthals, not Dinosaurs and made by French-Canadians from a Belgian novel.
