Dr Van Nostrand Posted December 23, 2022 Share Posted December 23, 2022 Good morning, While beach walking yesterday, we found this mass. It is mineral, dense and hard. Perhaps you can offer a suggestion as to what it is. thank you regards. D location: Atlantic ocean Florida Brevard county Link to comment Share on other sites More sharing options...
FranzBernhard Posted December 23, 2022 Share Posted December 23, 2022 Welcome to TFF from Austria! Not a fossil, I think. Yes, mineral, rock, ore, industrial intermediate product or industrial waste product. How dense? Heavier than a usual rock (granite, limestone)? How hard? Scratch test? Whats the color of the powder? Streak test? Franz Bernhard Link to comment Share on other sites More sharing options...
Dr Van Nostrand Posted December 23, 2022 Author Share Posted December 23, 2022 Density roughly that of limestone. Lighter than granite. scratch leaves streak on paint black powder released on scratch or chiseled fairly hard material 1 Link to comment Share on other sites More sharing options...
Rockwood Posted December 23, 2022 Share Posted December 23, 2022 Some of those darker inclusions look suspiciously like fossils to me. Teeth maybe ? 1 Link to comment Share on other sites More sharing options...
digit Posted December 23, 2022 Share Posted December 23, 2022 Possibly a phosphate nodule with black manganese crystals precipitated on the surface (if the streak it's leaving is blackish). Cheers. -Ken 1 1 Link to comment Share on other sites More sharing options...
Dr Van Nostrand Posted December 23, 2022 Author Share Posted December 23, 2022 Yes there are a few flat smooth inclusions that look like teeth Link to comment Share on other sites More sharing options...

Dr Van Nostrand Posted December 23, 2022 Author Share Posted December 23, 2022 Well thanks for the ID. I feel like a dork thinking it was bone. What era? regards. D Link to comment Share on other sites More sharing options...

digit Posted December 23, 2022 Share Posted December 23, 2022 In Florida, depending on what formation it came from you are looking at the general rage of Miocene through Pleistocene. There is some tiny amounts of Oligocene and more Eocene Ocala limestone further north in the state but the lower half is generally Miocene or younger. If you are possibly spotting inclusions of something like teeth this could suggest a coprolite but gator poops are pretty much chalky dissolved carbonate material with zero detail of the original bones.

Harry Pristis Posted December 23, 2022 Share Posted December 23, 2022 Maybe it's something covered in goethite (bog iron). Or, maybe it's just a bit of scrap iron with a puffed out crust of iron oxide (rust). At any rate, "D", you're safe giving it a whack on the sidewalk to find out. That is, it's not a fossil. http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...
digit Posted December 24, 2022 Share Posted December 24, 2022 Yup. It's whack-worthy if you wish to investigate what it looks like inside. Cheers. -Ken Link to comment Share on other sites More sharing options...
