Why did Lord John want to capture a Pterodactyl to take back to

England?​

Lord John wanted to capture a Pterodactyl and take it back to England to show the world that the claims made by Professor Challenger were true.

Explanation:

The question concerns the novel, The Lost World, written by Sir Arthur Conan Doyle. The novel is an adventure of four men into the lost world of South America where a world of dinosaurs was established.

In the book, Lord John Roxton wanted to capture a Pterodactyl and take it back to England because he wanted to show it as a proof to Professor George Challenger's claim that dinosaurs still exist in a remote part of the world.

The textual evidence is,

"‘Don’t you think other people besides Professors can

want to know things?’"
