D. John Barrie

David John Barrie (born 22 December 1947), often known as John Barrie or D. John Barrie, is an Australian natural historian and paleontologist known for his contributions to fossil excavations in South Australia. His work has been published in peer-reviewed journals and is represented in the collections of the South Australian Museum in Adelaide. An extinct species of primitive snake, Wonambi barriei, has been named after him.

Scientific Contributions Barrie participated in fossil excavations at Henschke's Quarry near the World Heritage-listed Naracoorte Caves National Park from 1981 to 1998. Specimens recovered during these excavations, including partial skeletons of a phylogenetically significant primitive snake, Wonambi naracoortensis, and over a thousand remains of Megalibgwilia ramsayi, part of the echidna family, are housed in the South Australian Museum. Barrie's work on Wonambi snakes has been credited by academic herpetology researchers. At the time of Barrie's discovery, and for some two decades thereafter, W. naracoortensis was the most completely known fossil snake discovered in the Australian continent. There are two known species of Wonambi snakes, one of them, W. barriei, was named in honour of Barrie, for collecting and preparing most of the material of W. naracoortensis.

Art and Illustration Barrie’s palaeoart has been commissioned by Flinders University and featured in scientific publications. In 2023, his illustration of Dynatoaetus gaffae, a Late Pleistocene raptor, was published in Alcheringa and used as the journal’s cover image.

His work was also featured in The Guardian Australia, accompanying coverage of prehistoric Australian birds. Barrie’s reconstructions have additionally been credited in independent science reporting, including The Conversation, Phys.org, and ScitechDaily, where his artwork accompanied coverage of extinct Australian raptors.

Public engagement In 2019, Barrie was interviewed on the Aussie Wildlife Show podcast, where he discussed his fossil excavation work and the significance of Australia’s prehistoric megafauna.
