Shark Tooth?

Can anyone tell me what this might be? I found it at riverside country park in medway on the beach and think it might be a sharks tooth.

    Re: Shark Tooth?

    Hello and welcome to the forum. This is rather difficult without a 'hands on'  examination. It might be but I don't think it is. It's more likeley to be the partial internal cast of a burrow in flint worn out of the nearby chalk and 80 - 85 myo. However, it appears to be covered in come sort of mineral deposit. It migght help me if you were firstly to give it a good srub with a brush in water and then, leaving it wet, re photograph it, both sides and the profile with a scale (a ruler is best) in natural overcast light. Secondly, can you scratch the main arched area (to the right) with somethingl made of steel ?

    Regards

    Colin

    Agree with Colin's train of thought - certainly not a shark tooth.  Crustacean burrow preserved in flint with a chalk outer boundary and a tad of iron staining.
