AcadianofNS Posted March 11, 2018 Share Posted March 11, 2018 Found two pieces of stone this weekend.. would like to know the timeframe and what they are ... if anything other than twigs. Found in Cape Jack, Nova Scotia A Beach on St George's Bay. Link to comment Share on other sites More sharing options...

caldigger Posted March 11, 2018 Share Posted March 11, 2018 Interesting whatever they might be. I like the way the long brownish one near the bottom of the plate fades in and out of the rock. Link to comment Share on other sites More sharing options...

Rockwood Posted March 12, 2018 Share Posted March 12, 2018 You are in an area where this is most likely Carboniferous plant material. The larger piece looks to be from the cortex of a lycopod, although flattened calamites is also possible. The strap like 'leaf' could be from a Cordiates. 1 Link to comment Share on other sites More sharing options...
Plax Posted March 12, 2018 Share Posted March 12, 2018 what Rockwood said, also reminds me of Triassic plant frags but no good if mapped carboniferous Link to comment Share on other sites More sharing options...

I usually avoid maps, and the area does have Mesozoic rocks so this should be investigated. If you can find anything that could be a clam I believe it would tend to indicate the earlier date.

"Silurian age rock outcrops in the Arisaig area are one of the best in the world" Arisaig beach only 30 mins shoreline from this beach. I'll see what I can find.

Rockwood Posted March 13, 2018 Share Posted March 13, 2018 The original post is not Silurian. The rock must not be from the same source as most of the beach fossils. Edit: I am assuming that these are larger than paper match stick scale items. Link to comment Share on other sites More sharing options...
KimTexan Posted March 13, 2018 Share Posted March 13, 2018 The chunk of rock on the left: the darker part definitely looks like fossilized plant material. Similar to petrified tree wood, but I don’t think it is tree wood. It looks very similar to some of the fossilized palm that I find in the North Sulfur River here in Texas. Palms and tree ferns are not composed of “wood” as wood is defined as “The secondary xylem of trees and shrubs, lying beneath the bark and consisting largely of cellulose and lignin.” Taken from my Farlex dictionary. As such, tree wood has the rings seen in cross sections, but ferns and palms don’t have typical rings. Tree ferns trunks are modified rhizomes and what we would call the bark on their trunks is actually a root mantle, if I’m not mistaken. I’m not sure about the lighter gray rock around it. That could be fossilized root mantle or it could be a concretion that formed around the woody material. I’m not familiar with fossils from your area though. May we have a pic from the end of the rock, which would be the truck cross section and something for scale? The other rock, it is hard to tell what they are. I have found similar things in shale/clay like material from the Austin Chalk, Cretaceous period here in Texas in a marine environment. Here are 2 pics of 4 examples. It is a repeating pattern, which I have seen many times that cannot be mere coincidence. I wish I knew what they were. Yours have some similarities. There is the oval leaf shape in juxtaposition with a straight stem shape, but these were all found in proximity to Inoceramus clams. Link to comment Share on other sites More sharing options...
KimTexan Posted March 13, 2018 Share Posted March 13, 2018 Sorry mine have no scale, but the largest oval is about 4 cm long. The smaller ovals are maybe 2 cm long. I never found a whole Inoceramus clam in the area, but the largest fragment of clam was 10 inches (25 cm). So the whole could easily have been 40-50 cm. I give that info in case my shapes in shale/clay are proportional to the clam size. Link to comment Share on other sites More sharing options...
Plax Posted March 13, 2018 Share Posted March 13, 2018 Cape Jack is mapped as carboniferous so we are looking at a coal aged plant assemblage. this is in reply to the initial inquiry. Link to comment Share on other sites More sharing options...

I've got a few pieces of Stigmaria imprint on same beach so makes sense. Link to comment Share on other sites More sharing options...
