Micro-CT Scan Reveals Diet of Opalized Australian Plesiosaur Fossil
Researchers from the Australian Museum and Australian National University used micro-CT scanning technology to analyze the stomach contents of 'Eric,' an opalized plesiosaur fossil discovered in 1987 at Coober Pedy. PhD candidate Joshua White led the study with collaborators Aleese Barron, Tim Denham, and Matt McCurry, examining the fossil without damaging it. The analysis identified fish vertebrae and gastroliths, providing insights into the marine reptile's diet. This non-invasive approach advances understanding of prehistoric ecosystems and could help predict how modern marine mammals might adapt to environmental changes.
