Wrangellian Posted August 19, 2017 Share Posted August 19, 2017 Anyone know Mt Isa stuff? I received this trilobite from @Jesuslover340 and noticed this other kind of 'starburst' item on the plate with it. No idea what it could be, but it looks like something.

Miocene_Mason Posted August 20, 2017 Share Posted August 20, 2017 Thinking about buying one of these myself, they are very pretty. as for the starburst, it just looks like it may have been hit with something, doesn't look much like a fossil to me, but if @Foozil knows someone, better ask them. “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...
Haravex Posted August 20, 2017 Share Posted August 20, 2017 The starburst impression looks like an impact, as the surrounding of it is sharp and not smooth like an impression. Link to comment Share on other sites More sharing options...
