CindyLoo68 Posted June 28, 2019 Share Posted June 28, 2019 I am wondering if anybody else has ever come across a fossilized Seabiscuit that is showing some form of crystallization Link to comment Share on other sites More sharing options...
Al Dente Posted June 28, 2019 Share Posted June 28, 2019 That is a common occurrence. The part where it isn't translucent is filled with sediment. The rest was hollow until groundwater deposited calcite, filling the void. 1 Link to comment Share on other sites More sharing options...
CindyLoo68 Posted June 28, 2019 Author Share Posted June 28, 2019 So would this be a crystalized fossil of a seabiscuit or is this a fossilized Crystal of a Seabiscuit? Link to comment Share on other sites More sharing options...
Manticocerasman Posted June 28, 2019 Share Posted June 28, 2019 crystalization is a form of fossilisation. the organnic and hollow parts are replaced by minerals over time thus creating the fossil. those minerals can create crystals in the hollow spaces and keep growing until everything is filled up. It is common to see that small geodes form inside of fossils In your specimen this gives a spectacular result resulting in a partialy translucent fossil. growing old is mandatory but growing up is optional.

aplomado Posted July 1, 2019 Share Posted July 1, 2019 Yes, the fossil urchins in my neck of the woods are filled with yellow crystals! Link to comment Share on other sites More sharing options...
