New trilobites

Amazing new trilobites have been found in Morocco with details of their anatomy preserved intact.

Fossils are usually flattened by the weight of deposited sediment above them as they lie on the sea floor after death or following burial, or by subsequent crushing of the rock formed from the sediment, during tectonic movement. In the case of these trilobites, however, the fossils show little or no distortion. As the delicate exoskeletons are complete, it is likely that this gentle burial followed an initial sudden engulfment that suffocated the trilobites.
