Not exactly the Golden Ration but very similar to the Fibonacci Spiral.
I found this and photographed with the Nikon F2 camera on Fomapan 200 film in my garden during the test of the very old developer ilford ID-11 that I got some time ago. This developer is from the year 2000, the film expired in 2006 and the camera created in 1972 and the Fibonacci Spiral composition is from 12th century A.D - not a Golden Ratio? :-)))
some more frames from the same roll of Fomapan film :
