Bohemia
Bohemia ( ; ; ) is the westernmost and largest historical region of the Czech Republic. In a narrow, geographic sense, it roughly encompasses the territories of present-day Czechia that fall within the Elbe River's drainage basin, but historically it could also refer to a wider area consisting of the Lands of the Bohemian Crown ruled by the List of Bohemian monarchs, Bohemian kings, including Moravia and Czech Silesia, in which case the smaller region is referred to as Bohemia Proper as a means of distinction. Bohemia became a part of Great Moravia, and then an independent principality, which became a Kingdom of Bohemia, kingdom in the Holy Roman Empire. This subsequently became a part of the Habsburg monarchy and the Austrian Empire. After World War I and the establishment of an History of Czechoslovakia (1918–1938), independent Czechoslovak state, the whole of Bohemia became a part of Czechoslovakia, defying claims of the German-speaking inhabitants that regions with German ...

Trilobite
Trilobites (; meaning "three-lobed entities") are extinction, extinct marine arthropods that form the class (biology), class Trilobita. One of the earliest groups of arthropods to appear in the fossil record, trilobites were among the most successful of all early animals, existing in oceans for almost 270million years, with over 22,000 species having been described. Because trilobites had wide diversity and an easily fossilized mineralised exoskeleton made of calcite, they left an extensive fossil record. The study of their fossils has facilitated important contributions to biostratigraphy, paleontology, evolution, evolutionary biology, and plate tectonics. Trilobites are placed within the clade Artiopoda, which includes many organisms that are morphologically similar to trilobites, but are largely unmineralised. The relationship of Artiopoda to other arthropods is uncertain. Trilobites evolved into many ecological niches; some moved over the seabed as predators, scavengers, or ...

Asaphida
Asaphida is a large, morphologically diverse order of trilobites found in marine strata dated from the Middle Cambrian until their extinction during the Silurian. Asaphida contains six superfamilies (Anomocaroidea, Asaphoidea, Cyclopygoidea, Dikelocephaloidea, Remopleuridoidea and Trinucleioidea), but no suborders. Asaphids comprise some 20% of described fossil trilobites. In 2020, the superfamily Trinucleioidea was proposed to be raised to an order ( Trinucleida) and removed from Asaphida. Morphology The Asaphids generally have cephalon (head) and pygidium (tail) parts similar in size, and most species have a prominent median ventral suture. Heads are often flat, and carapace furrows in the head area are often faint or not visible. Thoracic segments typically number 5 - 12, though some species have as few as two and some as many as 30. They also generally have a wide doublure, or rim, that surrounds the cephalon. This causes some specimens to be described as having a chara ...

Ordovician
The Ordovician ( ) is a geologic period and System (geology), system, the second of six periods of the Paleozoic Era (geology), Era, and the second of twelve periods of the Phanerozoic Eon (geology), Eon. The Ordovician spans 41.6 million years from the end of the Cambrian Period Megaannum, Ma (million years ago) to the start of the Silurian Period Ma. The Ordovician, named after the Celtic Britons, Welsh tribe of the Ordovices, was defined by Charles Lapworth in 1879 to resolve a dispute between followers of Adam Sedgwick and Roderick Murchison, who were placing the same Rock (geology), rock beds in North Wales in the Cambrian and Silurian systems, respectively. Lapworth recognized that the fossil fauna in the disputed Stratum, strata were different from those of either the Cambrian or the Silurian systems, and placed them in a system of their own. The Ordovician received international approval in 1960 (forty years after Lapworth's death), when it was adopted as an official per ...

Otomar Pravoslav Novák
Otomar Pravoslav Novák (16 November 1851 – 28 July 1892) was a Czech paleontologist. A student of Joachim Barrande, he worked at the University of Prague and specialized in the trilobites. Novák was born in Königgrätz (Hradec Králové), son of government officer Johann and Aloisia née Piperger. He became interested in paleontology early in life thanks to the influence of his uncle Karel Feistmantel (1819–1885). He studied at the grammar school in Prague followed by medical studies at the university until 1875. He did not complete his studies and in 1873 he became an assistant in paleontology under Antonín Frič at the museum. He then studied at the University of Prague and in 1879 his dissertation was on the bryozoa of the Bohemian cretaceous. In 1879 he became an assistant to Jan Krejčí. Around 1874 he studied the Silurian fauna along with Joachim Barrande and began to work along with Wilhelm Heinrich Waagen. He worked at the University of Vienna for two years under ...
