Continuation of the Table<br />
One of the problems of Palaeozoic biota reconstruction is determining whether<br />
fossil remains fo<strong>un</strong>d in the oryctocoenosis are autochthonous or allochthonous. This is<br />
usually estimated by use of transportation traces on the skeletal elements, more precisely<br />
the degree of post mortem wear. If this wear is considerable, it almost certainly indicates<br />
long transportation <strong>and</strong> possible introduction of alien animal remains to the<br />
taphocoenosis. The most accurate approach towards this problem is to regard as<br />
autochthonous only articulated or at least semi-articulated skeletal parts. In Table I this<br />
regards only the East Greenl<strong>and</strong> <strong>and</strong> Andreyevka localities. However disarticulated,<br />
the Red Hill remains were also regarded as autochthonous by Daeschler (2000). All the<br />
rest are formally regarded as allochtonous despite the possibility of long pebbling within<br />
the same basin <strong>and</strong> biotope which was the original dwelling place. This indeterminate
