Fossilz Posted December 9, 2017 Share Posted December 9, 2017 I found this today on the beach under a clay cliff, it is known for agate And chalcedony to be found on this beach, what would I call this, it looks like some sort of a bone maybe?

ynot Posted December 9, 2017 Share Posted December 9, 2017 Agate. Agate can form a botryoidal surface while growing. Sometimes there will be a separation along the layer lines. If convex, looking at the top side, if concave, then the underside. Agate can make "limb casts", but I do not think that is the case here. 1 Darwin said: " Man sprang from monkeys."

abyssunder Posted December 9, 2017 Share Posted December 9, 2017 It reminds me of Lithophysa . The conical radiating structures visible in the first picture look like biconoids / multiconoids. picture from here " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.

Rockwood Posted December 9, 2017 Share Posted December 9, 2017 I can imagine it being a geodized tabulate coral. Link to comment Share on other sites More sharing options...

If the conditions of the deposition change - larger quartz crystals can form. These crystals are intergrown and misshapen. That is what You have with the glassy fragments looking pieces. Where the individual quartz crystals have separated. 10 hours ago, Rockwood said: I can imagine it being a geodized tabulate coral. With no hollow inside? No septia? inconsistent size and shapes?
