Ekorus ekakeran
Overview
Ekorus ekakeran was a mustelid of Late Miocene Africa. Relatively long legs ended in short, sturdy feet. Its combination of limb features invites comparison even with familiar members of the weasel family.[1]

Key facts
The combination of long legs and short, sturdy feet is intriguing. Research on a skeleton from Lothagam, Kenya, describes these features. We can examine the overall impression of the limbs separately from the structure at their ends.[1]
Time and place
It is a Late Miocene animal known from Lothagam in present-day Kenya. The broad setting of this interval is approximately 11.6–5.3 million years ago. Evidence from limbs and feet helps reveal an ancient African mustelid.[1][2][3]
The time range describes source context, not the complete duration of this species.
Size, form and skeleton
Research describes relatively long limbs and short, sturdy feet. Its teeth have also been compared to those of cats. Limbs, feet, and teeth can be examined as separate body regions.[1]
One study estimated the body mass of Ekorus ekakeran specimen KNM-LT 23125 at approximately 40 kg. The calculation applied a predictive equation from earlier research, providing a sense of the size of this ancient mustelid with elongated legs.[4]

Habitat and reproduction
What functional questions arise from long legs combined with short, sturdy feet? Ekorus appears in a study comparing elbow and forelimb form in carnivorous mammals. It is an example of investigating how a body was used through the shapes of its bones.[1]
Fossil discovery
A study of skeleton KNM-LT 23125 from Lothagam described its limbs and feet. Ekorus was examined in the broader context of comparisons of elbow form among carnivorous mammals. The legs of one animal lead to several kinds of functional comparison.[1]

Research questions
How can similarities and differences be found in equivalent body regions? The limbs, feet, and teeth of Ekorus each raise different comparative questions. Examining features region by region makes the overall impression more specific.[1]
Observation
After looking at the length of the legs, examine the short, sturdy structure of the feet. Separating parts with different proportions helps explain why the skeleton of Ekorus draws attention.[1]
