A comparison of carbon/oxygen isotope ratios from the tooth enamel of two early proboscideans, Moeritherium and Barytherium to other animals of the same era (circa 37 mya) revealed to researchers the possibility of a ancient, semi-aquatic animal, linking the speculated split of dugong and elephant from a common ancestor. "The scientists" (as the article begins; that's some lead) said that they have:
...substantial evidence to suggest that modern elephants do have ancient relatives which lived primarily in water. The next steps are to conduct similar analyses on other elephant ancestors to determine when the switch from water to land occurred, and to determine exactly when the now fully-aquatic sirenians split from their semi-aquatic proboscidean relatives.
What a strange ancestry...

Definitely the best thing about the hyraxes (hyraces?) are their teeny, tiny tusks. In some photos it looks like the hyrax has a teeny, tiny cigarette dangling out of its mouth, like a small, furry Humphrey Bogart. "I ain't no rodent, lady. Now scram."
(Ooh. "Small, furry Humphrey Bogart." Check your search logs for that one. Bound to pick up some yiffy types with bait like that.)
