Uropygi is an arachnid order comprising invertebrates commonly known as whip scorpions or vinegaroons. They are often called uropygids. The name "whip scorpion" refers to their resemblance to true scorpions and possession of a whiplike tail, and "vinegaroon" refers to their ability when attacked to discharge an offensive, vinegar-smelling liquid, which contains acetic acid. The order may also be called Thelyphonida. Both names, Uropygi and Thelyphonida, may be used either in a narrow sense for the order of whip scorpions, or in a broad sense which includes the order Schizomida.

Geralinura is an extinct genus in the family Thelyphonidae, commonly known as whip scorpions. Fossil evidence found in the midwestern United States and the United Kingdom indicates that this genus lived during the mid-to-late Carboniferous period. Unlike the subchelate pedipalps of modern whip scorpions, the pedipalps of Geralinura are spiked and non-chelate, suggesting that the modern trait evolved at a later point in time.
