Populations in Chile were thought extinct by 1953, but the animal was found to inhabit an area in the Antofagasta Region in the late 1900s and early 2000s. The animal may be extinct in Bolivia and Peru, though one specimen found (in a restaurant in Cerro de Pasco ) may hail from a native population.
The supply of chinchillas slowly diminished, with the last short-tailed chinchilla being seen in 1953, causing skin prices to increase drastically.

Archaeologists have discovered evidence of red fox breeding in the late Iron Age on Orkney, off the northern coast of Scotland. After the attack of the Vikings in Scotland around 800 CE, the breeding is said to have stopped. [30] The earliest records of breeding mink for fur in North America were in the 1860s.
Armadillos are small mammals with a bony armored shell. There are 21 extant species in the Americas, 19 of which are only found in South America, where they originated. Their much larger relatives, the pampatheres and glyptodonts, once lived in North and South America but became extinct following the appearance of humans.
