What Can Opalised Fossils Tell Us About Ancient Environments

Fossils play an important part in how we interact with and understand our environment - including those environments long past. 

There's a wealth of fossils in Lightning Ridge, which can teach us much about the mid-Cretaceous, and that's exactly what today's guest, Sherri Donaldson, is working on.

We caught up with Sherri for World Environment Day to talk about how these ancient creatures can teach us not just about the past, but also our future.
