A new Xiphosuran from the Triassic sediments at Brookvale, New South Wales
Amongst the many interesting fossils obtained from the shale beds at Brookvale is an almost complete specimen of a Xiphosuran. These Brookvale sediments are generally considered to be of freshwater origin. They contain insects as well as fish, Estheria and Leaia. As Xiphosura occur in both freshwater and marine sediments this specimen throws no light on the probable nature of the sediments.
The Xiphosuran shows many interesting features, the species being considered in a new genus for which a new family is erected.
