Goticaris

Goticaris is a genus of small (1 mm long) extinct Cambrian arthropods, known from the Orsten lagerstätten in southern Sweden. It appears to have several apomorphic features, notably including a single large compound eye.

The head of Goticaris has an unusual anterior projection of the head that bears a single large and what are possibly two smaller stalked compound eyes. There are four pairs of appendages on its head. The first pair of appendages are treated as antennae, and the other appendages on head are biramous. The mouth opens on the ventral surface in front of the second pair of appendages. The abdomen has four segments with two pairs of paddle-shaped appendages, and a telson.

Ecology
According to its close relative Cambropachycope's eye structure, Goticaris was probably a predator.

Classification
It is hesitantly presumed to be an early offshoot under the clade Pancrustacea in original description. It consists of the species Goticaris longispinosa. Other organisms, including Henningsmoenicaris and Martinssonia also discovered in Orsten, may exist at a similar place on the phylogenetic tree. Collectively, this may have implications for the origins of the crustaceans. However, later study placed this genus outside Pancrustacea, and just treated as stem-group Mandibulata.
