I believe I have found the fossils in the Mercia mudstone of Ancient Cleveland North East England . I have recently collected several ripple and bed samples from the river Leven , and after cleaning Ime sure there are fossils in the samples .
Above close up of what I believe is a fossil in the Mercia mudstone of Cleveland .
The image above shows what I believe to be the fossil remains of a Triassic life form to the bottom left of the two reduction spots , the image zooms quite well .
