Skimmed it. Weird read. I'll come back for a proper read later. Intriguing. Nummulites are (were? Thought they were extinct?) single celled : "A nummulite is a large lenticular fossil, characterised by its numerous coils,[1] subdivided by septa into chambers. They are the shells of the fossil and present-day marine protozoan Nummulites, a type of foraminiferan. Nummulites commonly vary in diameter from 1.3 cm (0.5 inches) to 5 cm (2 inches)[2] ... Fossils up to six inches wide are found in the Middle Eocene rocks of Turkey" https://en.wikipedia.org/wiki/Nummulite https://en.wikipedia.org/wiki/Nummulite
