It could be a coincidence that they look like them. They can be thin and hard though. 1 Link to comment Share on other sites More sharing options...

Fossildude19 Posted September 8, 2019 Share Posted September 8, 2019 Scrub a small area with a wire brush. If it comes off, it's lichen. If not, we will need more focused photos, preferably taken in daylight.

dinosaur man Posted September 8, 2019 Author Share Posted September 8, 2019 They didn’t come off fossildude19 here’s a better photo Link to comment Share on other sites More sharing options...
Fossildude19 Posted September 8, 2019 Share Posted September 8, 2019 Are they throughout the entire rock? What does the other side look like? Lighting is good, but I can't make out any details on the rings. Try to get a closeup of those. My guess at this point would be Oncolites, or puddingstone.

Kane Posted September 8, 2019 Share Posted September 8, 2019 Most likely lichen. I’ve seen similar along the southern Nova Scotia coast. 1 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
Mark Kmiecik Posted September 8, 2019 Share Posted September 8, 2019 Lichens create a mild acid which over time dissolves some of the rocks they cling to. When the lichens die or are otherwise removed from the stone -- wave action is one possibility -- they leave behind a pattern that matches their original form. I have seen lots of this in Canada and Minnesota, Northern Wisconsin and Michigan. It seems that lichens die off en masse occasionally for some reason and leave behind evidence of their existence. It could be argued that this is a very recent trace fossil. 3 Mark. Fossil hunting is easy -- they don't run away when you shoot at them! Link to comment Share on other sites More sharing options...

Fossildude19 Posted September 8, 2019 Share Posted September 8, 2019 It would appear the majority of people here are correct. This looks very similar to concentric boulder lichen, Porpidia crustulata. See below: Image from HERE. Maybe evidence of them having been there? 2 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Rockwood Posted September 8, 2019 Share Posted September 8, 2019 Would it be an adequate test to see if they are affected by peroxide ? Link to comment Share on other sites More sharing options...

Lichens are common as dirt everywhere on the planet, even in polar regions. They are one of the things that break rock down into sand particles. At my place in Minnesota, when I still had some land there, boulders the size of cars were completely covered with lichens. Living lichens in some cases are tougher than leather and cling to the rock surface so strongly that they are very difficult to remove even with a blade. They grow in shade or sunlight, wet or dry locations and there are more than 15,000 known species. There are species well-adapted to any environment. They attach to any surface they can find including the fur and hide of many animals. Really neat organisms once you begin to study them. 2 Mark.

That was my first thought, too. I guess oncolites and lichens are both cyanobacteria, so everyone is right. Link to comment Share on other sites More sharing options...
Plax Posted September 9, 2019 Share Posted September 9, 2019 I'd give it a wack and see if the shapes continue into the rock. 1 Link to comment Share on other sites More sharing options...

Definitely, there's only so much we can get from looking at the photos. Mark. Fossil hunting is easy -- they don't run away when you shoot at them!
