Hey everyone, hope you're all doing well
I'm aware that many marine fossils come from animals that lived in not-very-deep seas. For instance, the Late Cretaceous European chalk was deposited in a sea that was around 300 meters deep.
However, are there any fossils that are thought to be of organisms from very deep water? (e.g. from bathyal, abyssal and hadal zones, deeper than 2000 meters)
Thanks for any info I'd find it cool to read about "abyssal fossils" if they exist!
