An interesting find from Avalus.
I found this little piece of (oil) shale next to roadway currently under maintenance/construction. It is the imprint of a fern and something else. The stone might have come from the near Saar-region, where coal was dug up from the ground. The ‘waste-rocks’ are used as road-gravel.
‘We are walking on history’ gets a deeper meaning here, I guess.
(I need to take a picture of the fossil fern next to a living fern in spring :) )
