Wonderful collection of sea shells

Замечательная коллекция морских раковин

The shell (related to the word "cancer") is an external protective skeletal formation that covers the body of some invertebrate animals and microorganisms. Conchiology studies invertebrate shells. The most interesting from the point of view of practical use and collecting are the shells of mollusks.

Accumulations of shells of various groups of organisms play an important role in the formation of some types of bottom sediments and sedimentary rocks.

Skeletons of diatoms, accumulating on the seabed, form diatomaceous ooze, which later turn into diatomite, trefoil and flask.

The accumulation of shells of planktonic foraminifera leads to the formation of globigerin ooze, named for one of the genera (Globigerina). Shells of large foraminifers - fusulinide and nummulitide - can play a significant role in the formation of limestones.

Shells of mollusks participate in the formation of shell limestone, and congestions of shells of the pterygopod mollusks form pteropods.
