Keira thinks it would be cool to have a little pterosaur as a pet, but not all pterosaurs are small and cute. And what on Earth is one doing flying around on their island anyway?

When Dr Kang, a palaeontologist from the museum, comes to visit the Beehive she brings a young pterosaur with her. She explains that she expected the pterosaur eggs that she'd gone to look at would be either fossils or fakes - but when one hatchd, she knew she'd made a big mistake and that something strange was going on.

Pterosaurs have been extinct for millions of years, so where did the eggs come from?

The Heroes guess they've been brought through a time gate from the past - but who would do that, and why?

There's only one way to find out. They'll have to find the time gate and see who is using it.
