"Discovery of 'Dune'-like Selkirkia Worm Species Alters Ancient History"
Originally Published 1 year ago — by NPR
Scientists have discovered new evidence of a species of predatory worms called Selkirkia that lived 25 million years after they were previously thought to have vanished from Earth, challenging previous assumptions about the history of life on our planet. These inch-long creatures with spiny throats lived during the Cambrian period around 500 million years ago and were believed to have been wiped out by a mass extinction event. The discovery suggests that the boundaries between different periods of Earth's ancient history may be more blurred than previously thought, prompting a reevaluation of our understanding of ancient life.
