Aspects of the sugar-refining industry from the 16th to the 19th century

This paper considers some aspects of the sugar-refining industry in Britain from the 16th to the 19th century. The pottery types involved are defined, and illustrated by examples from different parts of the country. The method of manufacturing sugar loaves is discussed, and the technology is placed in a wider context, drawing upon archaeological and historical evidence from the Old and New Worlds.

A short-snouted trematosauroid (Tetrapoda,Temnospondyli) from the Early Triassic of Australia: the oldest known trematosaurine

The trematosauroid temnospondyl Tirraturhinus smisseni gen. et sp. nov. from the Arcadia Formation of central Queensland, Australia, is described on the basis of its rostrum. This is the first trematosaurine (short-snouted) trematosauroid from Australia, and is considered to be most closely related to Tertrema acuta from Spitzbergen. Tirraturhinus smisseni occurs alongside lonchorhynchine (long-snouted) trematosauroids in the Arcadia Formation; the co-occurrence of both trematosauroid morphotypes in that fauna is repeated in a number of non-marine Early Triassic faunas elsewhere in Pangaea. The Arcadia Formation is probably Griesbachian (earliest Triassic), so that T. smisseni is the oldest known trematosaurine.
