Abstract: | A reassessment of sanitheres Diamantohyus and Sanitherium based on important new material from Kenya, results in the view that the group warrants familial status separate from the Suidae with which it has been grouped until now. Analysis of distribution patterns and co-occurrences with other faunal elements in East Africa indicates that sanitheres probably preferred to live in or near wet habitats, notably swamps and lake margins. The geographic distribution and biostratigraphy of sanitheres is examined. |
