Greg.Wood Posted February 8, 2018 Share Posted February 8, 2018 Here is my collection of small/micro fossils from the Arkona formation in Southern Ontario.

Manticocerasman Posted February 8, 2018 Share Posted February 8, 2018 Oh, fantastic post Greg, nice pictures Do you have the exact age of the fossils. looks like a late devonian fauna to me. growing old is mandatory but growing up is optional.

Thx Kane 380MYA, thats about the same age as the Frasnian - Fammenian border where I collect fossils in my area growing old is mandatory but growing up is optional.

That is certainly an exciting time as it marks the Kellwasser extinction event. The Givetian was still pretty pleasant times, at least where these fossils were once situated. In the Arkona proper, there is a great deal of turbidity, caused by storms, accounting for all the mud, which was constantly being reworked. ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

Jeffrey P Posted February 8, 2018 Share Posted February 8, 2018 Magnificent collection there Greg. I'm really impressed by both the specimens and the photography. I'm not used to see such biodiversity of micro fossils from the Devonian. Congratulations and thanks for sharing. 1 Link to comment Share on other sites More sharing options...

Tidgy's Dad Posted February 8, 2018 Share Posted February 8, 2018 Incredibly good photos of a fascinating micro fauna. One of those crinoid stems is simply astonishingly beautiful and I love the tentaculites and the hyoliths in particular Life's Good! Tortoise Friend.

Ludwigia Posted February 8, 2018 Share Posted February 8, 2018 Nice collection! And the great thing about it is that it doesn't take up much space I think you've done just fine with the ids. Is that all from one dig or did you take several loads? Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...

I took two trips, one bucket to start and see if it was worthwhile then I went back and filled 3 more when we had a bit of a thaw. I'll have to look for some gravel beds next year where the river has done some of the work for me...a 5 gallon bucket of clay only yields about 1-2 cups of matrix.

IsaacTheFossilMan Posted October 24, 2021 Share Posted October 24, 2021 I know this is an old thread, but the photography is absolutely crazy here! If you wouldn't mind me asking, what did you take them with, and what microscope? I'm looking to upgrade my gear! ~ Isaac; www.isaactfm.com "Don't move!
