Hi,
Carrying out a spring clean and I found this from an old school geology field trip I took in about 1984.
This would have been from the Birmingham Ridge (UK) of Keuper bed Sandstone which dates to the Triassic. Unfortunately I cant be more precise on the location as my memory has faded and I have lost my old notes but it would have been somewhere in the proximity of Barr Beacon. According to the literature this would have been a river delta - to my eye these look more like ripples you'd find on a shallow beach. Or maybe they are nothing - I thought I'd share to see what the experts think.
What I love about these - if they truly are fossilised ripples - is their fragility. A true snapshot in time frozen forever.
Thanks for looking,
Carl
