This is a fossil of unknown origin, it was allegedly found burried in sand near the shore of the Chesapeake Bay in Virginia; or possibly on the banks of the James River. The previous owner believed it to be an intervertebral disc of some kind of whale. It is clearly fossilized and has some areas encrusted with a sand like mineral. It also has a few spots where a shiny black mineral has been deposited. Can anyone provide an identification and possible an estimated age?
Dear colleagues I found this strange small thin disk on the surface of the sand in the desert in Giza, Egypt (just outside Cairo). It's very thin and has concentric lines, each line being made up of small dots. I can't find anything like it on various fossil sites that I looked at. It's only 2.5cm (one inch) in diameter and very thin. Many thanks to anyone who has the time to reply, even if it's just speculation (it's fun guessing too !)
I got this as part of an estate. You might notice I've posted a few things from there. Anywhere, I have no idea what this is? Maybe a geologist could hazard a guess. It definitely is a metal of some sort. It has a diameter of 3 inches (7.6 cm). It's thickness is around ⅛" at its thickest point in the center. The edge is sharp enough that this could be used as a weapon in a pinch. I wish I could send you a sidewise photo, too. Notice the shell on the one side. I have another disk like this without the shell. Is this a modern-day man-made creation or was it made by natural forces. Yes, nature sometimes does make fantastic, regular patterns. Could this be one of them? I have no idea on where this came from or how it got to myself prior to the estate. Thank you for your help.
