This is a very interesting tool specimen ( a "slipper" axe) with what I interpret to be iconic properties, largely because of the 'feline' sense I get when I look at this side of the artifact under these lighting conditions and can see the possible human modification to the handaxe to feature an iconic image. It compares favorably to other crude cat representations I have come across over the years. The two incised lines terminating at their meeting at a position approximating the bridge of the feline nose is a visual trigger to us that this is indeed a cat and it has been given a required element of life, a nose.
Sri Lankan and Romanian examples. These figure stones from Eurasia have been featured earlier on this blog and demonstrate the artistic convention of incising two lines to create a V or ^ shaped nose to disambiguate or animate face icons.
I propose The Arkfeld Site example displaying the same artistic nose marking convention links it to Eurasian peoples through a symbol-making cultural tradition.
I wrote in the posting last year "I have suspected the common artificial application of nose and nostril details on many figure stones seen on this blog may have been a way for Stone Age peoples to add a symbolic 'breath of life' to the rocks."
