The Evolution of the Mollusc Shell

Molluscs'' calcareous shell makes them very different from other animals, various as they may be. The assumption, the first molluscs of the early Carian period (about 550 to 580 Million years ago) had been creatures crawling on the ocean floor, explains the division of a mollusc''s body into a soft ventral side crawling on the floor and a dorsal side exposed to the environment, which …

What is concrete shell architecture - InnovaConcrete

A concrete shell, also called “thin shell” concrete structure, is composed of a thin shell of concrete formed in such a way as to be self-supporting, often with no interior columns or exterior buttresses.The shells are most commonly flat plates and domes. They can also take the form of ellipsoids or cylindrical sections. The first concrete shell dates back to the 2nd century.
