Kate Trinajstic, the lead researcher from Curtin University's School of Molecular and Life Sciences and the Western Australian Museum, said the discovery was remarkable, given that soft tissues of ancient species were rarely preserved, and it was even rarer to find 3D preservation. "As a palaeontologist who has studied fossils for more than 20 years, I was truly amazed to find a 3D and beautifully preserved heart in a 380-million-year-old ancestor," Trinajstic said in a statement.
