Foraminifers

Although they were protozoans, Nummulites (diminutive form of the Latin nummulus 'little coin') are still known to have left behind comparatively large fossils. As they always added further chambers to their calcareous housings, shells up to 10 cm in size were found. The animal itself sat in the anterior chambers and stretched out pseudopodia to feed on other small creatures.The last picture shows the backside. There are more nummulites there.Age: Middle Eocene, Lutetian;Locality: Magyarpolány, Ajka district, Bakony Mountains, HungarySize of several nummulites: up to 3 cm each; matrix: 5 x 9 x 2.5 cmDue to technical reasons, colors on photos may differ slightly from those of the original specimen.

In spite of actually being unicellular animals, Nummulites (diminutive form of Latin nummulus, "little coin") produced comparatively large fossils. By adding more and more chambers to their calcareous shells, they could leave behind fossils up to 10 cm in size. The animal itself sat in the anterior chambers and stretched out pseudopodia to feed on other small creatures.Age: Middle Eocene, Lutetian;Locality: Magyarpolány, Ajka county, Bakony forest/mountains, HungarySize of several nummulites: up to 3 cm each; matrix: 8 x 8 x 3 cmDue to technical reasons, colors on photos may differ slightly from those of the original specimen.
