The Sprigg lecture series provides visitors with access to the latest research and thinking around scientific and cultural discoveries at a local and global level and to engage with scientific ideas that affect them and their world, now and in the future.

These free lectures commemorate the life of Dr Reg Sprigg AO, a remarkable South Australian geologist who discovered the world’s oldest fossilised animals in the Flinders Ranges in 1946, now internationally recognised as the Ediacara fossils.

Online bookings for Sprigg lectures will open one month before the event. 

The 2016 Sprigg lecture program will be available from this page in the near future.

Queens (and kings) of decay: Osedax boneworms and whalefalls 

Osedax is a recently discovered group of annelid worms where the females (mainly), with a little help from endosymbiotic bacteria called Oceanospirillales, feed on the bones of whales and other mammals in the deep sea. Osedax males are normally dwarfs that are thousands of time smaller than females. Females may therefore have large 'harems' of hundreds of males in their tubes. The known diversity of Osedax species is rapidly increasing, as is the evidence for Osedax on fossils bones. Professor Rouse will discuss what we know about the biology, life history and phylogeny of this extraordinary group of worms.

The Sprigg Lecture Series is supported by Arkaroola Wilderness Sanctuary and Bundaleer Wines.
