Traditional and computed tomographic (CT) techniques link modern and Cenozoic fruits of Pleiogynium (Anacardiaceae) from Australia

Computed tomography (CT) and traditional techniques were used to study the internal morphology of modern fruits of Pleiogynium timoriense (DC.) Leenh., and phosphatized and silicified fruits that were considered to belong to the genus. The results demonstrate that phosphatized fruits from the Oligocene–Miocene Dunsinane site at Riversleigh and silicified fruits from the Oligocene Glencoe Site, which are both in Queensland, are referable to Pleiogynium. The Riversleigh material (Pleiogynium wannanii Rozefelds, Dettmann & Clifford sp. nov.) is very similar to extant P. timoriense (DC.) Leenh. Both possess locules that, in the vertical axial plane, are asymmetrically reniform and enclosed by a two-layered endocarp, the inner layer woody and resistant to decay, the outer of fibres and parenchyma, surrounded by a mesocarp of fibres and sclereids and a parenchymatous exocarp. The outer mesocarp is sculpted by meridionally arranged, elongate depressions (germination apertures) situated at the dorsal surface of each locule; erosion of the mesocarp and outer endocarp provides passage for emergence of the embryo’s radicle on germination. The silicified material from Glencoe (P. parvum Rozefelds, Dettmann & Clifford sp. nov.) is smaller in all its parts and has locules that are ovate in the vertical axial plane. Discrete, cap-like, opercula are not evident in the fruit wall of the fossil and extant fruits studied. The presence of Pleiogynium, and associated taxa, indicates the existence of rainforest communities at Glencoe, and mixed open forest/rainforest at Riversleigh during Oligocene–Miocene times. The multilocular, fossil fruit described as Pleiogynium mitchellii Collinson, Manchester and Wilde from the Eocene deposits at Messel Quarry, Germany, is not considered to belong in the genus, as evidence of elongate depressions on the dorsal surface of the fruit stones has not been demonstrated conclusively, and its internal morphology/anatomy differs significantly from that of Pleiogynium.

Mapping Submerged Landscapes Using Multibeam Bathymetric Data: a case study from the north coast of Ireland

This paper outlines work currently being undertaken to reconstruct submerged archaeological landscapes off the north coast of Ireland. This research uses the recently‐completed Joint Irish Bathymetric Survey (JIBS), which has provided full‐coverage high‐resolution multibeam bathymetric data for the sea‐bed off the north coast. This data has been examined for evidence of past sea‐level change and been used to produce palaeo‐geographic reconstructions of the past landscape, which in turn have facilitated the identification of ten areas of high archaeological potential. The results presented here will form the basis of a future programme of archaeological survey and prospection. © 2010 The Authors

Abstract

The existence of sacred places is a widespread phenomenon throughout Palestine, one which is reflected in various types of local sites, such as water sources, graves, caves, trees and constructed shrines (maqams). In Islamic Palestine, the construction of maqams originated with the Fatimid (a Shiite group), in order to memorialise and 'greet' distinguished figures descended from the family of the prophet Muhammad. Thereafter, the Sunni faith actively adopted this concept and dedicated more than 2,500 sites to prophets, holy people, the righteous and martyrs. The sacred place of Sheikh Shihab ed-Din, like several hundred other Islamic maqams throughout Mandate Palestine, is located on top of a natural hill commanding a panoramic view. This place has held religious importance during the Byzantine and Ayyubid-Mamluk periods, right through to the present day. This paper studies the construction of the maqam as well as its related archaeological remains. It is based on a field study, a survey of the literature, and archaeological explorations conducted during a brief excavation season.
