Oil Shale Trilobites
Todays excursion took us, among many things and places to the oil shale deposits (Sv. Alunskiffer) at Andrarum in the south east of Skåne (Scania) in Sweden. These shales dates from the middle and late Cambrian periods (around 500 Ma)
These are my first trilobites ever! They are very small, Agnostus pisiformis, around 0.5 mm - 4 mm in size are seen in the first picture (size slightly increased in this photo). The two larger Olenus attenuatus in the last picture are around 1-3 cm in size when found complete (Ive only got fragmets). One headshot (the "UFO"), one topside back (the "ribs"). The observant viewer can of course see traces of several more Olenus in the image.
