Averianov, A.O., and Krasnolutskii. 2009. Stegosaur remains from the Middle 
Jurassic of west Siberia. Proceedings of the Zoological Institute of the 
Russian Academy of Sciences 313(2):153-167.

ABSTRACT: The Middle Jurassic (Bathonian) Itat Formation at Berezovsk Quarry, 
Krasnoyarsk Territory (West Siberia, Russia) has produced abundant remains of 
stegosaurs. Numerous isolated teeth are found at various microvertebrate sites, 
and associated skeletal remains, mostly vertebrae, ribs, and ilio-sacral block 
fragments were excavated at the Stegosaur Quarry. These remains likely belong 
to one taxon which is characterized by numerous secondary ridges on one crown 
side in cheek dentition, six vertebrae in the synsacrum, four sacral and one 
dorsosacral ribs, lack of dorsal process on the transverse process in anterior 
caudals, moderately expanded tops of the neural spines in anterior caudals, and 
large triangular transversely thin dorsal dermal plates. The combination of 
these and other features is not characteristic for any other known stegosaur 
taxon and the Berezovsk stegosaur likely represents a new taxon. Among known 
stegosaurs it is most similar with Stegosaurus from the Late Jurassic and Early 
Cretaceous of North America and Asia by having numerous secondary ridges on 
teeth, a right angle between the supraacetabular flange and the anterior iliac 
process of ilium and in the structure of the dorsal dermal plates. It differs 
from Stegosaurus by plesiomorphically unexpanded tops of the neural spines and 
lack of dorsal process on the transverse processes in the anterior caudal 
vertebrae. The Berezovsk stegosaur is among the oldest stegosaurs in the fossil 

Danilov, I.G., and Syromyatnikova, E.V. 2009. New material on turtles of the 
family Nanhsiungchelyidae from the Cretaceous of Uzbekistan and Mongolia, with 
a review of the nanhsiungchelyid record in Asia. Proceedings of the Zoological 
Institute of the Russian Academy of Sciences 312(1/2):3-25.

ABSTRACT: This paper presents a review of all known records of turtles of the 
family Nanhsiungchelyidae in Asia, includingdata from 37 localities. Among new 
materials described herein are remains of nanhsiungchelyids (Hanbogdemys sp. 1 
and 2 and Nanhsiungchelyidae indet. 1–10) from 12 Early and Late Cretaceous 
localities of Mongolia and Uzbekistan. Nanhsiungchelyidae from the Early 
Cretaceous (Aptian–Albian) of Mongolia are reported for the first time. 
Reassessment of the published data on Asian nanhsiungchelyids allows us to 
change taxonomic status of many previous findings from Basilemys sp. or 
Zangerlia sp. to Nanhsiungchelyidae indet. In addition, we refer Bulganemys 
jaganchobili to Hanbogdemys. The latter genus thus has the widest temporal 
distribution (from Cenomanian to Campanian) among nanhsiungchelyids in Asia. 
Our analysis of the nanhsiungchelyid record in Asia shows that the record is 
richest in the Cenomanian–Campanian of Mongolia, whereas the Maastrichtian 
record from Mongolia should be considered questionable. These facts emphasize 
the particular importance of the Mongolian record of nanhsiungchelyids for 
understanding the diversification and evolution of this group.

Syromyatnikova, E.V., and Danilov, I.G. 2009. New material and a revision of 
turtles of the genus Adocus (Adocidae) from the Late Cretaceous of middle Asia 
and Kazakhstan. Proceedings of the Zoological Institute of the Russian Academy 
of Sciences 313(1):74-94.

ABSTRACT: This paper reviews shell material of the turtle genus Adocus 
(Adocidae) from the Late Cretaceous of Middle Asia and Kazakhstan. Three 
previously recognized species of Adocus from this area are described in detail 
based on published and new material. The previously recognized species are A. 
aksary (Dzharakuduk, Uzbekistan; late Turonian), A. foveatus (Kansai, 
Tajikistan; early Santonian), and A. kizylkumensis (Khodzhakul, Khodzhakulsay 
and Sheikhdzheili, Uzbekistan; early Cenomanian). Material of additional forms 
of Adocus are described, two of these are named as new species: Adocus 
dzhurtasensis, sp. nov. (Dzhurtas, Kazakhstan; Santonian – early Campanian), 
Adocus bostobensis, sp. nov. (Akkurgan, Baybishe, Buroinak, and Shakh-Shakh, 
Kazakhstan; Santonian – early Campanian), and Adocus sp. indet. (Itemir, 
Uzbekistan; Cenomanian).

Skutschas, P.P., Martin, T., and Sun, G. 2009. The co-occurrence of 
non-lissamphibian temnospondyls and salamanders in the Late Jurassic of the 
southern Junggar Basin (Xinjiang Autonomous Region, NW China). Proceedings of 
the Zoological Institute of the Russian Academy of Sciences 313(2):143-148.

ABSTRACT: So far, the Jurassic co-occurrence of non-lissamphibian temnospondyls 
and early temnospondyl lissamphibians was known only for the Middle Jurassic 
Balabansai Svita in the Fergana Depression, Kyrgyzstan and the Peski Quarry 
near Moscow, Russia. Here we report the co-occurrence of non-lissamphibian 
temnospondyls and lissamphibians (salamanders) from the Late Jurassic 
(Oxfordian) Qigu Formation of the Liuhuanggou locality in the southern Junggar 
Basin, China. This represents a considerable temporal and geographical range 
extension for the nonlissamphibian temnospondyl-early lissamphibian faunal
