urban fossil Posted July 31, 2018 Share Posted July 31, 2018 Discovered this about 10 km upstream from the Mackenzie River bridge on the north bank while fishing. I was thinking it was covered in plant impressions, although I do not know what era it is so I will leave that for the experts to decide. I'm always grateful to hear everyone's thoughts and opinions, as well as learn something new. Thanks Link to comment Share on other sites More sharing options...
Rockwood Posted July 31, 2018 Share Posted July 31, 2018 They don't look like plant pieces to me. Something that has been metamorphosed beyond recognition is my best guess. It is just a guess though. Link to comment Share on other sites More sharing options...
minnbuckeye Posted July 31, 2018 Share Posted July 31, 2018 If I zoom in on the lighter areas, I see what look like crinoid bits attached?? Or is this some form of metamorphic creation? Link to comment Share on other sites More sharing options...
Fossildude19 Posted July 31, 2018 Share Posted July 31, 2018 The oval shape reminds me of a Platycrinites crinoid columnal.

jdp Posted August 1, 2018 Share Posted August 1, 2018 Weird. A lot of the rock up there is metamorphic, so it may be nothing, but there are some aspects of that which look vaguely vertebrate too. I'll look into this and get back to you. Link to comment Share on other sites More sharing options...
Wrangellian Posted August 1, 2018 Share Posted August 1, 2018 Looks like we need to get a look at a geologic map to narrow down the possible age of the rock (keeping in mind it may have been deposited there by the river or the glaciers...?) 1 Link to comment Share on other sites More sharing options...
Ludwigia Posted August 1, 2018 Share Posted August 1, 2018 Looks intriguing. Lots of possibilities there from impressions to burrows to conglomerate to metamorphic. I agree with Wrangellian. We need more precise info. Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
urban fossil Posted August 14, 2018 Author Share Posted August 14, 2018 I emailed the NWT Geological Survey asking for their input about my find and what age the rock might be. This was the response: "There isn’t too much I can say about these based on the photos and description. If they were collected in-situ from an outcrop, then they are probably Late Devonian age from the Paleozoic era. There are a few formations composed of carbonate and shale that outcrop in that region. If the samples were collected from rubble/beach rock, then they could’ve been transported in from elsewhere and age determination becomes more uncertain. As for the fossils, I cannot ID them, but it looks like various broken-up fragments in random orientations, indicating that they were part of sediment that was transported some distance before being deposited."
