    I found a PDF of the paper and I think I was right about Pachydiscus — check for yourself.

    I can’t download the paper, but the species listed includes <span style=”text-decoration: underline;”>Pachydiscus</span> which is my bet.

    It looks like a river-worn quartz pebble.

    It looks modern, because it looks mostly made of bone, with little of no mineralization.  If it was from a fossil fish, you might expect it to have more of the bone replaced with rock minerals like silicates.

    I agree with the bullfish predentary bone from a modern fish. It is definitely NOT from a sea urchin. That must’ve been a good size fish!

    My best guess is a badly worn shark tooth

    I think you need to post a picture with a little more detail, especially of the head region in order to attempt an ID.  Did the specimen come with a note telling where it was from by any chance?
