Bolca Location: Northern Italy Age: Eocene
Not much work has been conducted on the taphonomy
of Monte Bolca fossils.
The fish are often fully articulated.
There is good soft part preservation in these fish with organs,
skin and scales being preserved in some cases.
Pigmentation patterns of the skin may even be preserved in
The Lagerstautte layers in the Monte Bolca deposits
are well laminated (i.e. lacking any bioturbation) and commonly
contain pyrite and bitumen. These two features are indicative
of anoxic or subanoxic conditions, which would have inhibited
decay and precluded many scavengers.
