    Howdy!

    To start things off, I am new to the forum, so if this is in the wrong spot, could a moderator move to appropriate location!

    I am posting because I have found something over a year ago, and to this day have been unable to iD it. The certain something was found during a day of windsurfing out on Lake Ontario, in Kingston specifically. It was found on a pebble beach on one of the nearby islands. I have included pictures, and physical characteristics below.

    Characteristics:

    -Can't scratch glass, but is harder than fingernails
    -Hollow inside
    -Very dark brown color
    -Very smooth exterior
    -Comes to 4 distinct 'points'
    -Uniform left to right structure

    Haha... woah! Thanks for the quick reply; haha and I was hoping for something a little more exotic.... but it is good to know what it is. From the description it doesn't really seem like I should have found it in this region however, but I guess things do migrate!
