Which dinosaurs are rumored to exist on Roraima?

Question

There are bird-like dinosaurs rumored to exist on Roraima. What are they and are there any more species?

Answer 1

Considering that birds are cladistically considered theropod dinosaurs, I would expect that a wide selection of Brazilian species do make their home there.

Answer 2

Roraima is a sparsely populated Brazilian state. There are no living dinosaurs there, because dinosaurs are extinct. It was at one time speculated that Roraima, consisting mainly of a large plateau, may have been sufficiently isolated from the rest of the world for supposedly extinct species to have endured into the modern age, but any application of this idea to dinosaurs would be unfounded; dinosaurs are large enough that modern technology would spot them easily. There could perhaps be relict species of insects or flowers there, though. Maybe even larger animals like birds or lizards. But no dinosaurs.

Answer 3

Only in fantasy: some expeditions inspired Sir Arthur Conan Doyle to write his classic adventure yarn, The Lost World, in 1912, with dinosaurus and hundred adventures.
