This striking fossil block showcases four beautifully preserved specimens of Ductina vietnamica, arranged naturally across a matrix of fine grey stone. The trilobites themselves stand out with a warm yellowish hue that contrasts vividly against the cool grey background, highlighting every detail of their smooth, iconic form. Largest genal soine is almost 4 cm on this specimen. Specimens of Ductina are already prized for their distinctive eyeless morphology and streamlined shape — a fascinating adaptation to life in deeper or darker marine environments. But finding multiple complete individuals on a single slab, in such aesthetic and well-balanced composition, is exceptionally rare. This piece is not only a scientific treasure, but also a visual masterpiece — a frozen moment from the ancient Devonian seas of what is now Vietnam, offering both beauty and insight into the evolutionary history of trilobites. Slab is 12 x 7 cm.
