A mélange of rock textures from the fault zone at Clarke Head, near Parrsboro in Nova Scotia, Canada. The geology here is extremely complex and I have only just begun to unravel what is going on. Key research papers with precise details are not easily accessible. Others are a bit too generalised to enable me to identify exactly each rock type that I photographed….for the moment. I will update when I can be sure I have accurate identifications. The variety was wide and included igneous, sedimentary and metamorphic rocks. It is the same place that I photographed the satin spar gypsum. The colours, textures, and patterns are amazing.

I wonder if you can see crinoid “stems” in the limestone layer between the shale layers that I see in photos number 5 and 19 (numbered in the e-mail version). We see them in the limestone layer between shale layers in the cliffs at Ohio’s Vermilion River. Never have seen the top parts of the crinoids there, though.

Hello Linda,
The sequence in which you would have viewed the images would not necessarily be in the designated numerical order because the image gallery pictures are displayed in random order. Each image is numbered and given a description which can be seen when you view the photographs in the gallery on the actual blog site. Images 7 through to 14 are all Carboniferous limestone strata from the Windsor Group. I have reviewed all of them in high resolution and I am not able to see any evidence of crinoid stems but fossils, including crinoids, are common in this type of sedimentary rock and would not be unexpected. I think you must have better eyesight than me. [The other images on this post show igneous or metamorphosed rocks and these would not be fossiliferous.]
I have often seen crinoid stems, or fragments of them, in Carboniferous limestone on the Gower Peninsula in South Wales, and pictures of them can be seen in….

I have only once seen a crinoid stem with the crown of arms in place and that was on the Worms Head Causeway in Gower: pictures 013 and 014 in

I love receiving these images (one beach fanatic to another) Is this set from an earlier set in Canada or have you been back again?
I hope to get to see the rocks at Worms head that you posted for myself at some point. Might not get to Canada.

These pictures from Clarke Head were taken on a trip I made to Nova Scotia in late May to early June this year. I had previously travelled around several of the Maritime provinces in Canada in 2014. The two trips generated something like 15,000 photographs. I still have a lot to write about from both visits. Great beaches and fascinatingly complex geology in Canada but also in the U.K. Lots still to explore at home.

I’m sorry, Jessica. I didn’t mean to imply that I saw the crinoid parts in your photographs; was just wondering whether you had ever found them in that sort of limestone layer (between layers of shale). I’m sure my eyes are no better than yours! Thanks for the links. How exciting it must have been to see these fossils in person.

Sometimes when I take a photograph, I am concentrating on only one aspect of what I see, only to discover something entirely new when I look at the image later. I just thought maybe I had missed something.

I’m frequently pleased by a photograph that has elements—interesting, appropriate ones—that I didn’t notice when I took the photograph. But then there are those shadows falling in just the wrong place that I didn’t notice at all at the time . . .
