An exceptionally well preserved new species of ostracod (Crustacea) with soft parts in Baltic amber

A well-preserved ostracod in Baltic amber has been analysed with noninvasive methods by synchrotron radiation. A micro-tomographic image stack was prepared. The appendages are visualised as images and drawings are based on photographs of different images planes provided. The result is a description of a new species, Cypria kempfi, from the Eocene of Northern Germany. The way the fossilisation of this aquatic animal may have occurred is discussed. The possible ecological preferences of the species are considered.
