Austrolimulidae

Extinct family of arthropods

Austrolimulidae is an extinct family of horseshoe crabs belonging to the infraorder Limulina. Members of the family are known from the Permian to the beginning of the Jurassic, though one species has been reported from the end of the Cretaceous. Austrolimulids are known for amongst the most extreme morphologies among Xiphosurids, including large elongated genal spines. Unlike living Limulids, Austrolimulids were likely adapted for freshwater and brackish environments.[1] They are considered to be the sister group to Limulidae, the group that contains all modern horseshoe crabs.[2]
