    Hi welcome!

     

    Sorry Guys, not coral, tooth or wood - This is a shard from a layer of "Beef Rock" from the "Shales with Beef" Member of the Charmouth Mudstone Formation which overlies the "Blue Lias Formation" between Monmouth Beach and Pinhay Bay.

     

    It is a mineral specimen composed mainly of calcium carbonate crystals.  Formally, it is called "cone-in-cone" structure (Google that).  I have tweaked one of your images.  It shows the fibrous texture well:-

    Below is an explanation provided by me to Charmouth Heritage Coast Centre
