Hi, I found an object on a beach on the Isle of Wight a few years ago and was told that it was a dinosaur bone fossil. I would like an expert opinion on whether it actually is, please!? It measures 2.2 inches length ways, 1.2 inches width ways and is about 1 inch tall. It looks porous and has small white specks over most of it, and has tiny sparkling golden flecks covering it. Have attached photos below. Thanks!
