Maslin Beach and Port Willunga: Sediments, fossils & unconformity

Sunday 24th September

Maslin Beach Pt Willunga beaches show a sequence of Tertiary sedimentary formations laid down in the Willunga embayment. As the rocks are gently dipping we will encounter each formation in turn as we walk along the beach. We will see clear evidence of the gradual uplift of the area in Eocene times, a variety of fossils and an unconformity in the top section of the cliff face.

Extinct megafauna at Lake Callabonna

Thursday 5th October  2023     Time: 7:45 pm

Lake Callabonna, where thousands of megafaunal animals became stuck in the mud, has a central place in the discovery of the Australian megafauna. In expeditions in 2014, 2018 and 2019 we rediscovered the 1893 campsite, relocated the 1970s fossil sites, and documented fossil deposits across a 12 by 5 km area of the lake. We documented 468 skeletons of Diprotodon, found the first Genyornis skull, found two new species of megafaunal kangaroo and found that all sites are of the same late Pleistocene age.
