Chimaera swimming over the sediment at the Kermadec Trench in the Pacific Ocean (depth: 1544 m). In the new study, scientists studied the behaviour of modern deep-sea fishes to understand the formation mechanism of Cretaceous trace fossils. Results reveal the earliest evidence for deep-sea vertebrates.
