Mowry Shale exposed in a road cut, Uintah Basin, Utah. The Mowry Shale or Fish-scale Beds because of the abundance of fish scales, is a dark-gray, siliceous shale that weathers silver gray; it is 10-70 m thick. 40Ar/39Ar of sanidine from a bentonite yielded an age of 97.17 +/-0.69 Ma, [3] thus is Cenomanian in age.
A fish scale is a small rigid plate that grows out of the skin of a fish. The skin of most jawed fishes is covered with these protective scales, which can also provide effective camouflage through the use of reflection and colouration, as well as possible hydrodynamic advantages.
The pearlescent substance used to coat various cores may contain essence d'orient, isinglass, fish scales, oyster scales, or mother-of-pearl powder, along with binders or dyes.

Keeled scales of a colubrid snake (banded water snake; Nerodia fasciata). In zoology, a scale (Ancient Greek: λεπίς, romanized: lepís; Latin: squāma) is a small rigid plate that grows out of an animal's skin to provide protection.
Ganoine or ganoin is a glassy, often multi-layered mineralized tissue that covers the scales, cranial bones and fin rays in some non-teleost ray-finned fishes, [1] such as gars and bichirs, as well as lobe-finned coelacanths. [2] It is composed of rod-like, pseudoprismatic apatite crystallites, with less than 5% of organic matter. [3]
These scale types are distinguished by their mechanical properties, geometric shape, and macroscopic alignments. Elasmoids are the typical oval shaped scales found on ray-finned fish. [27] These scales are known for their ultra lightweight, puncture resistant, and flexibility which allows for the propulsion movements required for swimming. [27]
