Rediscovered this after having it a few years. Found in Dorset. Looked rather bone-like and slightly porous in the centre so I picked it up off the beach. Just gave it the lick test, and it came out really quite sticky. Anyone got any thoughts as to what it might be?

Hi Jack,
Looks like a chert/flint nodule to me.

Hi Pete. That was my first thought (after a quick Google anyway). Does the 'lick test' have no bearing? I was under the impression flint was not porous and so couldn't have this effect.

Cheers

HI 
Weathered flint can become rotten i.e. partially de-silicified. In this state it appears to be porous. Your specimen has cavities that seem to contain recrystallized quartz (silica).

Hi, this is certainly Flint / Chert - 100%
