problematical fossil. Almost certainly brown algae. These have yet to be formally named.
Square 'tile' of lithographic Limestone. From a really old German collection. In the centre is a mass of 3D string like fossils. These have been interpreted as algae of some description. First time in over 40 years I have even seen one of these fossils
Jurassic, Uppermost Kimmeridgian, Tithonian, Solnhofener Plattenkalk.
Eichstatt, near Solnhofen, Bavaria, Germany.
Fossil : 4.5 x 3.5 cm.
