Seeing Andy's Victorian dinosaur reminded me of this cool sail-back monster in the old 50's movie Journey to the Centre of the Earth.
I've read that the actual lizard was a rhinocerus iguana as seen below. It had its sail glued on, poor sod.
There are other dinosaurs in the film, notably this red beast at the film's volcanic finale. I remember it making a startling trumpet like sound. How did they do that? A tuba?
The beast itself was actually a Tegu lizard like this but painted red.
Ultimately the red beast perishes under the lava of the Atlantean eruption at the film's close [I do hope the lizard didn't actually perish].
IMdB informs us that the lava in this scene was most likely oatmeal.
It suggests that it was used in the Time Machine's movie eruption as well.
I've no idea how they turned oatmeal into lava other than perhaps colouring it red. Do you?
