Cone shaped bony structure

Observation - Cone shaped bony structure - UK and Ireland. Description: I found this object in the soil whilst digging the garden - thought it was an old clay pipe at first but then realized it was more like a horn. Would appreciate any suggestions regarding identification, thanks
