Hello all - this is my first post here. I am posting a possible bone fragment my son and I found while beach combing here in Texas. It is from McFadden Beach near Galveston on the Texas coast after a recent storm. It is about 5 cm in length, 2 cm in with and ranges from 2mm to 5mm in thickness. It feels more like stone than bone - but I am not an expert in this field.
