Ocular coal of the mine Westende in Duisburg-Meiderich (germany), seam La Girondelle .
Exhibit in the german mining museum of Bochum. Supposed cause: "Pressure phenomena in coal". This explanation is inadequate and does not explain the complexity of the structure. The piece contains a bigger one and a smaller algae seaweed ball with dry tears. These are embedded and outwardly penetrated with layered alga seaweed. As expected this coal also contains many chondrums, here on the right most clearly.
Photo date: 1992
In the piece of Duisburg-Meiderich the following phycodic signs can be proved:

Chondrums in accumulation, this are in coal and rocks signs for beginning phycodic growth

Layered surrounding areas, on the right in clearest ones
