Found what l thought was bone in clay today at mappleton beach in East riding.
Can anyone help me out with this please. 
When you do the tongue test it's very sticky.

Sorry I can’t help, just curious about the tongue test. What is it and what does it tell you, please?

Hi Marion.
It's the tongue test lol
I thought I'd found bone  and did this test.
If it's sticky when your tongue touches it you've got a fossil. If it isn't it's rock. 
I'm only a newbie but have done it and the picture I put up looks like bone to me and is extremely sticky lol x

Basically if you put your tongue on a fossil it will be sticky. A rock will not be lol
I've given the one in my picture a good going over lol

Hello Lesley and welcome to the forum. You are nearly right with the tongue test - it only works with BONES - if a BONE sticks to your tongue , it if considered fossilised, if it is not fossilised, it will not stick - or said the first person Paleontology in the 1800's. Sir William Buckland. I have not tried it, but a) it could have harmful bacteria / fungi on it and b) it's not 100% imho.

Hi Colin.
It's very sticky and l won't do it againlol
What do you think it may be? Any ideas? It's definitely not rock it has an altogether different feeling.
I'm really pleased with it👍

Hi Lesley
your sticky bone seems to be full of small gritty/argillaceous inclusions which makes me think it could be a bit of impure chalk. Chalk is porous which may explain the stickiness on the tongue. Have you tried the acid test??

Hi Lesley
I'm assuming you don't have any 10% Hydrochloric acid. If you put some vinegar in a small glass and then add a small piece of your rock or whatever it is. If it contains calcite (CaCO3) it should give off small bubbles of CO2 gas. Vinegar is a very weak acid so you'll need to look very closely to spot the bubbles and it might help to heat the vinegar up in a microwave first. If you get no reaction then you can rule out calcite, chalk and limestone.
