The extraordinary fossil Harpes trilobite, measuring eight four millimetres overall, is a wonderfully articulated and fine specimen. Exotic trilobites have influenced some of the most iconic sci-fi films and helped shape the structure of some of the most sophisticated architectural buildings in modern times. The Harpes trilobite, with its unique patterning and streamlined aesthetic, is a species that never fails to intrigue. Its wide, heavily pitted brim, fringe with a curled rim, and elegant taper to the point of both cephalon long spines make it a true enigma. The eyes set back high on the glabella, and the well-defined thoracic segments add to its allure for inquiring minds. With reference once more to the Martian-looking brim, this wide brim with innumerable pitting could have aided the invertebrate lift, much like a hydrofoil. Again, this is the theory at this time. Palaeontologists theorise the possible functions of these anatomical features, either being a wide sieve to filter bottom sediments for food or to detect movement, a sensory organ. Over the 250,000,000-year range of the trilobites, many different morphological adaptions developed from free swimmers to bottom sifters. The expanded and pitted cephalic fringe, a distinct anatomical development seen in harpetids and trinucleids types, including the Harpes trilobite, is a significant area of study in palaeontology. This species, featured in a beautifully designed lucite display case...
