I once read a science fiction novel called The Lost World. What is the name of this novel?

The plot went like this: A group of modern people entered an isolated world (one of them was a painter).
The plot of the story was similar to other dinosaur novels. A group of modern people entered an isolated world (one of them was a painter). There were dinosaurs and indigenous primitive people. The indigenous people were red-skinned dwarves and would throw people down the cliff. There were sharp bamboos (like bamboos) at the bottom of the cliff. There was a lake, and by the lake lived the nest of pterosaurs. The smelly mud by the lake produced diamonds, a lot of them. Later, those people went out and made some money with diamonds. That was all he remembered. Thank you big brother and big sister for reading it patiently, please tell me if you know:) Thank you
The team didn't see the dinosaurs at first, but only the artist's painting. The artist seemed to have gone there earlier than them…Aiya, I'm so dizzy~I really can't remember.
