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
The words aurochs, urus, and wisent have all been used synonymously in English. But the extinct aurochs/urus is a completely separate species from the still-extant wisent, also known as European bison. The two were often confused, and some 16th-century illustrations of aurochs and wisents have hybrid features.
The word "urus" (; plural "uri") is a Latin word, but was borrowed into Latin from Germanic (cf. Old English/Old High German "ūr", Old Norse "úr"). In German, OHG "ūr" was compounded with "ohso" "ox", giving "ūrohso", which became early modern "Aurochs". The modern form is "Auerochse".
