An international team of scientists say they have new insight into how the very earliest animals survived after traces of what they described as the world’s oldest meal were found in a 550 million-year-old fossil.
The palaeontologists suggested that Kimberella was likely one of the most advanced creatures of the Ediacaran era with a mouth and a gut and digested food the same way modern animals do. “Scientists already knew Kimberella left feeding marks by scraping off algae covering the sea floor, which suggested the animal had a gut,” Brocks explained.
