Eric
The opalised skeleton of a small pliosaur (an extinct marine reptile) discovered in the Cretaceous rocks of Coober Pedy, South Australia in 1987. Saved for the Australian Museum by a national fund-raising appeal in 1993 by ABC's "Quantum" and a generous donation from Akubra, Eric is now on display in the National Opal Collection in Pitt St. Mall, Sydney.
