Verified January 2016   


Tinnunculite Mineral collectors recently discovered several new carbon minerals in guano deposits. The organic mineral tinnunculite is composed of uric acid and forms when droppings from a European kestrel, Falco tinnunculus, interact with the air and Earth materials. The mineral is named after the bird responsible for its existence. Type material is deposited in the collections of the Fersman Mineralogical Museum of the Russian Academy of Sciences, Moscow, Russia, registration number 4695/1.
