"… was lacking in so many features of the Old World―elastic weapons, for example, such as bows and catapults…"
What does " Old World―elastic" mean?
You are joining two separate things: "the Old World" and "elastic weapons".
The "Old World", in this context, is the Africa/Asia world from which the early migrating people came to Australia.
… "elastic weapons" are weapons like bows and catapults that derive their propulsion from the flexible and stretchable material used to make them.
