Tidgy's Dad Posted April 19, 2018 Share Posted April 19, 2018 Here are my agnostids. First up the Itagnostus interstrictus that several others have posted, all from the Wheeler Shale, Antelope Springs, House Range, Utah: These were teased out of rocks sent by Tony @ynot And a recent acquisition from the Wheeler Formation courtesy of Jay @DevonianDigger, this one's a little bigger at 7 mm.

MeargleSchmeargl Posted April 19, 2018 Author Share Posted April 19, 2018 Really nice stuff so far! Every single fossil you see is a miracle set in stone, and should be treated as such. Link to comment Share on other sites More sharing options...

No, just Wheeler Formation shale, Millard County, Utah. Here it is in its rock. It is beautiful isn't it? And my photography using the loop is improving a bit. 1 Life's Good! Tortoise Friend.
