Intrigued by the frequency of appearance, the finely preserved soft-tissue fossils of sponges, arthropods, annelid worms, and echinoderms took a closer look at such fossils and Dr Saleh formed a team and found that, while fossils of the hard parts of animals such as shells, sponge, and spicules were common in all sedimentary layers, soft-tissue fossils were restricted to the six layers deposited at intervals of 10,000 years.
