The Holocene occurrence of the European catfish (<i>Silurus glanis</i>) in Belgium: the archaeozoological evidence

An overview is given of the skeletal remains of the European catfish Silurus glanis found thus far in Belgian archaeological sites. These finds demonstrate that the species is autochthonous and allow documenting its occurrence and disappearance during the Holocene in the Scheldt and Meuse basins. Possible causes for the local extinction of this catfish are discussed

Guide for the identification of archaeological sea sturgeon (<i>Acipenser sturio</i> and <i>A. oxyrinchus</i>) remains

Remains of sturgeons (Acipenser sturio and A. oxyrinchus) are regularly found on western European archaeological sites. The identification of these isolated bones should ideally be carried out with the aid of a comparative skeletal collection, consisting of modern specimens of different sizes. Because such reference material of sea sturgeons (A. sturio and A. oxyrinchus) is relatively rare and dispersed over many different museums and institutes, a practical guide is presented here as an aid to the identification of the most commonly found archaeological sturgeon remains. This guide, which is based on observations made on 64 individuals housed in 13 different natural history collections, should allow identifying most archaeological sturgeon remains from western European sites. Presented are the morphological characteristics of the bones of the skull roof and circumorbital region (posttemporal, dermopterotic, parietal, frontal, dermosphenotic, postorbital, jugal and supraorbital), bones of the braincase (parasphenoid), opercular series (subopercle and branchiostegals), the palatoquadrate and associated bones and lower jaw (palatopterygoid, dermopalatine and dentary), the hyoid and gill arches with the hyomandibula, the isolated skeletal elements from the pectoral girdle (clavicle, cleithrum and supracleithrum), the bones of the fin and fin supports (pectoral fin spine, fin rays and fulcra) and the dorsal, ventral, lateral and accessory scutes. For each element, descriptions and pictures are provided of modern and archaeological specimens. Regression equations allowing fish length reconstructions on the basis of single bone measurements are given for 14 elements and the scutes. Finally, criteria for species identification are provided. In the case of the dentary, dermopalatine and palatopterygoid, these are differences in shape of the skeletal elements, whereas for the dermal bones the external surface pattern is diagnostic when reconstructed fish length is over one meter

Late 17^th century AD faunal remains from the Dutch 'Fort Frederik Hendrik' at Mauritius (Indian Ocean)

The fauna is described from a refuse layer, excavated at Fort Frederik Hendrik on the island of Mauritius and dating to the last quarter of the 17(th) century AD. The animal remains enable the reconstruction of the food procurement strategies of the Dutch inhabitants of the fort and document the fauna at a time when the island's original fauna had apparently already suffered heavily from human interference and from the negative impact of introduced species. The animal remains do not include any bones from the dodo, or other endemic birds, and neither is there evidence for the exploitation of the large, endemic terrestrial tortoises, also now extinct. Dugong, which are locally extinct nowadays, and marine turtles were also exploited as food, but the major meat providers were the introduced mammals: cattle, pigs, and especially, goat and Java deer. Fish was also a regular food resource and must have been caught in the local lagoon and estuaries. The absence of parrotfish and the relatively small size of the groupers suggest avoidance of these food items, probably out of fear of fish poisoning

Consumption patterns and living conditions inside Het Steen, the late medieval prison of Malines (Mechelen, Belgium)

Excavations at the Main Square (Grote Markt) of Malines (Mechelen, Belgium) have unearthed the building remains of a tower, arguably identifiable as the former town prison: Het Steen. When this assumption is followed, the contents of the fills of two cesspits dug out in the cellars of the building illustrate aspects of daily life within the early 14th-century prison. An integrated approach of all find categories, together with the historical context available, illuminates aspects of the material culture of the users of the cesspits, their consumption patterns and the living conditions within the building
