Jurassic Lark

1st October 2013 at Waterloo, Broadford Bay, Isle of Skye. This is an area of Jurassic sandstone and we'd come to find fossils. A fossilized dinosaur leg bone has been found here but our sights were set slightly lower.

 These large pink pebbles may be granitic.



 Looking back south westwards towards Broadford, with the granite hills of Beinn na Caillich (right) and Beinn Dearg Bheag in the background. In the foreground is the weathered grey Jurassic sandstone (?).



 More plates of weathered sandstone.



 Looks like a bit of limestone and a seam of yellow mineral.




Limestone at an early stage of formation.



More grey sandstone slabs. There are a very few small grey sand beaches on Skye, so things haven't changed that much in the last 200 million years.



There were quite a few tiny ammonite fossils scattered around.







 And several of these crater like structures.






This cellular pattern; is it lichen?



 Quoting Jo: "Well I have looked at other similar images and to me it does look like a cone from the species of Araucaria. These are trees that form cones. However fossils have only been found in the southern hemisphere, although they are of the Jurassic period, and as this period goes back 200 million years, these rocks could well have been in the southern hemisphere. Maybe I am over interpreting it just a squdge or a squidge!!! We need expert advise. Remember it has been exposed to tremendous pressures over a long period; to remain intact would be rather remarkable and it could well be squashed. It does have seed like indentations around the outer edges and the shape is almost there".



 And there was this segmented, worm-like thing.



 And a rough scallop-shaped entity. 



 The hills to the east exhibit a wiggly surface terrain.



 Back to Broadford.
