Eureka, California
"Eureka" received its name from a Greek word meaning "I have found it!" This exuberant statement of successful (or hopeful) gold rush miners is also the official motto of the State of California. Eureka is the only U.S. location to use the same seal as the state for its seal.
Aurochs
In Central Europe, the aurochs features in toponyms and heraldic coats of arms. For example, the names Ursenbach and Aurach am Hongar are derived from the aurochs. An aurochs head, the traditional arms of the German region Mecklenburg, figures in the coat of arms of Mecklenburg-Vorpommern. The aurochs (Romanian "bour", from Latin "būbalus") was also the symbol of Moldavia; nowadays, they can be found in the coat of arms of both Romania and Moldova. An aurochs head is featured on an 1858 series of Moldavian stamps, the so-called Bull's Heads ("cap de bour" in Romanian), renowned for their rarity and price among collectors. In Romania there are still villages named Boureni, after the Romanian word for the auroch. The horn of the aurochs is a charge of the coat of arms of Tauragė, Lithuania, (the name of Tauragė is a compound of "taũras" "auroch" and "ragas" "horn"). It is also present in the emblem of Kaunas, Lithuania, and was part of the emblem of Bukovina during its time as an Austro-Hungarian "Kronland". The Swiss Canton of Uri is named after the aurochs; its yellow flag shows a black aurochs head. East Slavic surnames Turenin, Turishchev, Turov, and Turovsky originate from the Slavic name of the species "tur". In Slovakia, toponyms such as Turany, Turíčky, Turie, Turie Pole, Turík, Turová (villages), Turiec (river and region), Turská dolina (valley) and others are used. Turopolje, a large lowland floodplain south of the Sava River in Croatia, got its name from the once-abundant aurochs (Croatian: ). The ancient name of the Estonian town of Rakvere, "Tarwanpe" or "Tarvanpea", probably derives from "Aurochs head" ("Tarvan pea") in ancient Estonian.
