Here we offer an interesting slab containing a
trace of some kind of millipede (probably Arthropleura).
It is (!!!)carboniferous in age (Stephan B/C) and was found in Puertollano, Spain.
One can clearly recognize a longer trace, several smaller prints and a
bigger sized wood. The longer trace goes strait across the plant.
The slab is unbroken, it measures about 28 x 27 x 2 cm.
Very old aged and rarely offered material, don´t miss this one!
