Description
Martinssonia is a small (roughly 1.5 mm long) arthropod, with eight pairs of appendages and ten segments including the eyeless head. It has a pair of antennae, twelve biramous appendages on its head and front two body segments and a final pair of uniramous appendages on its third segment. Martinssonia also seems to have a pleotelson, similar to modern crustacean larvae.[1]
Ecology
Martinssonia was presumably a benthic detritivore, stirring up food particles from the seafloor.[1]
Etymology
Martinssonia is named for Anders Martinsson, a former Professor of Palaeobiology at Uppsala University in Sweden. The species name, elongata, is derived from its long trunk.[1]
Distribution
Martinssonia is known from twenty-one specimens of different larval forms, all from the Orsten Lagerstätte in Sweden, alongside thirteen specimens now referred to as Musacaris[2]
