The defining idea is that Black keeps the option to meet White’s c-pawn and e-pawn choices flexibly, which is what separates it from the standard Pterodactyl and other Dragon-like Sicilian lines.

You can spot the sicilian defense hyperaccelerated pterodactyl beginner when Black has already fianchettoed the king’s bishop and is still avoiding an early ...Nc6, often aiming for a fast ...d5 break if White allows it.
