If I read Liepzig's 'Gondwana' plans correctly the entrance and exit exhibits are entitled 'Living Fossils'. This looks interesting and I think it's an appropriate theme to set the stage for the main display.
I immediately thought of horseshoe crabs and tuataras, but there must be others. Any suggestions as to what they might be? Or perhaps I ought to keep on topic for this thread by asking which of the animals that you'll never see in a zoo would you call living fossils?

Could be lungfish.
any forest elephants in captivity?
Whipsnade had a forest elephant which died in 1988. I made my first visit in 1989 so I only just missed seeing him.
