Cambronatus is a genus of Devonian arthropod from the Hunsrück Slate of Germany. It contains one species, Cambronatus brasseli.[1]
Cambronatus was roughly 7 cm long and somewhat resembled modern shrimp. The head was covered by a simple head shield longer than wide, with a raised margin. The first pair of head limbs were biramous antennae, with around 400 annulations on the longer ramus. The next four pairs were all relatively similar, with around 15 short podomeres, each with a stout spine. These appendages appear to have been uniramous, and what seems to be the fifth pair shows bunches of smaller, inward-facing spines. Eyes appear to be absent. The trunk consists of 11 segments, with overlapping tergites diminishing in length towards the posterior. The first ten trunk somites have uniramous limbs much like the head, however in this case the flap-like exopod is present. The most unusual feature of Cambronatus, however, is the eleventh trunk appendage. This appendage was triramous, with a flagella-like first ramus, alongside two paddle-shaped ones which formed a tail fan together with the telson. This telson was at least partially fringed with spines, with flagelliform structures on its tip forming a caudal furca.[1]
