PRK Posted May 26, 2014 Share Posted May 26, 2014 With all the mazon posts lately, it made me look closer at my material. What, if anything, are these little nodes? Link to comment Share on other sites More sharing options...
Rob Russell Posted May 26, 2014 Share Posted May 26, 2014 My guess is they're pieces of the opposing half that stuck to that one. But that's a guess. Hopefully Rob or Jack will catch up with your thread and give you a conclusive answer. Nice specimen! Rob Finding my way through life; one fossil at a time.

Plantguy Posted May 26, 2014 Share Posted May 26, 2014 Hey Paul, neat find/specimen. Kind of looks like some very small pyrite crystals at least to me. Will wait to see if Rob or Jack have seen that kind of stuff. Seems l have a sample somewhere with some small circular depressions that might be similar....will go look when I get the chance and post if worthwhile.

fiddlehead Posted June 2, 2014 Share Posted June 2, 2014 The dots on leaves like these are referred to in the literature as Excipulites. They are presently thought to be fungal growths in the leaves when they were alive. And can they be distinguished from pyrite or other later inclusions by the fact they often display the leaf venation on over their tops. Also they should be visible only on the fossil leaf and not on the matrix to be considered Excipulites. Hope this helps some, Jack 1 Link to comment Share on other sites More sharing options...
PRK Posted June 2, 2014 Author Share Posted June 2, 2014 (edited) Perfect! Just what I wanted to know, I thought it looked possibly organic. Thanks fiddlehead! Edited June 2, 2014 by PRK Link to comment Share on other sites More sharing options...
