Close Evolutionary experts recently identified how South African dinosaurs breathed using the European Synchrotron Radiation Facility ESRF's X-ray technology. The dinosaur, better known as the Heterodontosaurus tucki, had a breathing system that had been a puzzle for scientists up until today.

Using the brightest and most powerful synchrotron light source, the fossil of the 200 million-year-old herbivore giant Heterodontosaurus tucki was observed for additional details regarding its previous body formation. Albany Museum's expert and co-author of the study William de Klerk was the first to encounter the fossil way back in 2019 in South Africa's Eastern Cape, reports Science Daily reports.
