[MM] Kulbeckia sp.
DESCRIBER Nessov, 1993
TIME Cretaceous Late
FOSSILSITE Bissekt Formation, Dzharakuduk, Uzbekistan
Kulbeckia kulbecke (Nessov, 1993 ) > Kulbeckia rara (Nessov, 1993 ) > Kulbeckia kansaica (Nessov, 1993 ) > Kulbeckia sp. (Nessov, 1993 )
A dentary of Kulbeckia (URBAC 02−17, Kulbeckia new smaller sp. was recovered during the 2002 field season that is only 65–75% the size of most other specimens referred to K.
kulbecke (Archibald and Averianov 2003). Although this specimen groups with the larger specimens based on the isolated petrosals, it demonstrates that the full taxonomic and size range of “zalambdalestids” has yet to be recovered or recognized at Dzharakuduk. As noted under materials,one petrosal, ZIN C. 85045, was recovered from locality CBI−117 in the Aitym Forma tion. Based on the morphology of this specimen and the fact that dental remains of Kulbeckia sp. also have been recov ered from locality CBI−117 (Averianov and Archibald 2003), there is little doubt that this petrosal is referable to Kulbeckia.
