Auspex Posted November 23, 2008 Share Posted November 23, 2008 Nice! Is this a different shale than most of your other specimens, or will it turn red in time?

Guest Nicholas Posted November 23, 2008 Share Posted November 23, 2008 I have many fossils... like.. possibly 100 pounds of impressions that look like sigillaria. However they are lacking the uniform circle structures. Is that common during preservation or is it a different species. Link to comment Share on other sites More sharing options...

Hi Nicholas ,you say : they are lacking the uniform circle structures , leaf cushions ,sometimes in the basal part of sigillaria leaf cushions are lacking ,or they are distant between 2 circle structures , perhaps it is too much small to see ,do you try macrophoto ???? ,that is a possibily about preservation factory ,I don't think sigillaria trunks from nova scotica are so different !!!!!

RomanK Posted November 23, 2008 Share Posted November 23, 2008 Nice!Is this a different shale than most of your other specimens, or will it turn red in time? Shale become red due to oxidizing, mainly sulphur ox. You can see the burning tip I visited this weekend.
