Tables 2, 5, SOM: figs. S1, S2.
Material.—All from Buluk, east of Lake Turkana, Kenya; lower section of the Buluk Member, Bakate Formation, uppermost lower Miocene. Teeth ( SOM: fig. S1): KNMWS 12623, isolated incisor; KNMWS 12630, tooth fragments; KNMWS 12631, broken tooth cusp; KNMWS 12664, incisor fragment; KNMWS 65236, isolated incisor; KNMWS 65465, right p3?; KNMWS 65591, isolated left P2, possibly of a hyaenodont; KNMWS 65726, nasal and maxillary fragment with possible left I 3 in the size range of H. sulzeri or C. jitu sp. nov.; KNMWS 101012, isolated premolar.
Postcranial material ( SOM: fig. S2): KNMWS 31036 is a right astragalus fragment comparable in size with Crocuta . The articulation for the tibia is very narrow, much more so than that documented for species in Amphicyon and Panthera . The articulation is not deeply inflated like in Amphicyon , but resembles Panthera in this respect in being less inflated. KNMWS 65395, phalanx; KNMWS 65472, fragment of distal metapodial; KNMWS 65597, scapholunare of Cynelos or Hyainailouros ; KNMWS 65731, fragment of distal metapodial; KNMWS 65733, fragment of left proximal ulna. The latter presumably represents a carnivoran, as the anterior crest of olecranon runs straight proximally. KNMWS 101029 is also a left proximal ulna fragment. This specimen is slightly larger than KNMWS 65733, but is otherwise very similar in morphology. KNMWS 65766, fragment of a large right calcaneum; KNMWS 65797, large sacrum and last lumbar vertebra; KNMWS 101031, large right scapholunare, unlike Hyainailouros .
Remarks.—Several specimens from Buluk represent members of Hyaenodonta or Carnivora , but the remains are too fragmentary to be attributed to a specific taxon. None of these specimens indicate the presence of an additional taxon at Buluk.
