Another surprise, Daley said, was the sheer number of comb jellies found at the site. These carnivorous marine creatures are one of the most primitive on the tree of life, and studying them could help scientists retrace some of the first steps in animal evolution. In an article accompanying the study, she calls the new fossils â€œstunningâ€.
Apparently a massive underwater mud slide buried an entire ecosystem in the most complete detail. Not just the individual organisms but their ecological inter-connections.
