Where: Jalal-Abad, Kyrgyzstan (41.1° N, 73.5° E: paleocoordinates 41.1° N, 77.9° E)
• coordinate estimated from map
• small collection-level geographic resolution
When: Balabansai Formation, Bathonian to Bathonian (168.3 - 163.5 Ma)
• The mammal molar and ulna were found in the lowermost part of the red-colored interval of the Jurassic. The mammalian incisor or reptilian tooth came from the
•upper part of this interval and was found close to a distal fragment of a humerus of a frog and some other vertebrate remains. The locality where the incisor was found is situated 1 km west from the locality that yielded a molar and an ulna fragment.

Environment/lithology: marine; siliciclastic sediments
Size class: macrofossils
Collected by L. A. Nessov et al in 1992
