Description
The cracks in the concretions are then filled in with minerals such as calcite (yellow), aragonite (brown), and sometimes pyrite, causing very interesting patterns. They have often been described as looking like dragon's skin. They are frequently found as geodes with hollow, calcite crystal-filled cavities. More rarely, the fossils that originally started the formation of the concretion are still preserved in the septarian.
Possibly there is a good chance it is hollow with quartz geodes, or as its heavy could have crystal formation inside.
Would have been fun to break/cut it open, but, would rather hand it on to a Geologist/Collector to take a further look.
Hard to date, but researching 'could' be 50-70million years old.
