I gather Pam Cross's thesis on the woman and horse burial at Sedgeford
to to big to post online. She has had an article published, which she
says she will make available in PDF format to those interested:

of Deposition. European Journal of Archaeology 14(1-2): 190--209.
Burial of horses and horse-elements occurred throughout Europe during
the first millennium AD. These burials are prevalent in northwest Europe
and are perhaps more significant in Britain than previously realised.
This article explores the position and value of the horse within Britain
during this period, why the burials are likely to represent ritual
deposition and what they may indicate about the culture. Both horse
deposits and human-horse burials are linked to non-Christian burial and
sacrificial practices of the Iron Age and Early Medieval period and are
particularly associated with Anglo-Saxon and Viking Britain. Some of the
traditions appear to reflect the culture described in the Icelandic
Sagas, Beowulf and other legends and chronicles. Archaeologically, the
human-horse burials are also linked with high status individuals and
'warrior graves,' while complete-horse and horse-element burials may
represent ritual feasting and sacrificial rites probably linked with
fertility, luck and the ancestors.
