Placodermi  is an extinct class of armoured prehistoric fish, known from fossils, which lived from the Silurian to the end of the Devonian Period. Their head and thorax were covered by articulated armoured plates and the rest of the body was scaled or naked, depending on the species. Placoderms were among the first jawed fish; their jaws likely evolved from the first of their gill arches.

The territory of what is now Latvia  was existed close to the equator during the Devonian period. Devonian rocks contain various fossils of brachiopods and

molluscs.  Placodermi Asterolepis ornata specie is the most common fossils found in the Devonian fish fossils in Latvia - mostly only small fragments of bone plates.
However, in 1970's some unique discovery of the fossilized remains of the prehistoric fish are made. Nowadays, this specie is considered to be the most detailed studied Latvian Placodermi. The Placodermi specie depicted on the stamp,  studied by Jelgava-born  naturalist-paleontologist Eduards Eihvalds (1795-1876) , who gave the  scientific name for it in 1840.

Karl Eduard von Eichwald (Eduards Eihvalds), borned on 4 July 1795 in Mitau, Courland Governorate and dead on 10 November 1876, Saint Petersburg; Russian was a Baltic German geologist, physician, and naturalist, who worked in Russia.  Eichwald was a Baltic German born at Mitau in Courland Governorate. He became doctor of medicine and professor of zoology in Kazan in 1823; four years later professor of zoology and comparative anatomy at Vilnius; in 1838 professor of zoology, mineralogy and medicine at St. Petersburg; and finally professor of palaeontology in the institute of mines in that city.  He travelled much in the Russian empire, and was a keen observer of its natural history and geology.
