of dinosaur footprint from Lugeng of Yunnan Province, China. Memoir of the
Fukui Prefectural Museum 5:35-39.
ABSTRACT: Lufengopus dongi, a new ichnogenus and ichnospecies of theropod
dinosaur footprint is erected. The holotype is from the Upper Lufeng
Formation of the Middle Jurassic, Lufeng County, Yunnan Province of southern
China. Lufengopus dongi gen. et sp. nov. is characterized by its large size
(the maximum length is approximately 40 cm), and relatively wider width
between the second and fourth toes, the ratio of the maximum length to width
of the footprint is 1.25. The discovery of the large-sized theropod dinosaur
footprint provides a strong evidence for the potential findings of large
theropod dinosaur bones

Dinosaur footprints from the Lower Cretaceous of Inner Mongolia, China.
Memoir of the Fukui Prefectural Dinosaur Museum 5:1-14.
ABSTRACT: More than a thousand dinosaur footprints, ranging in size from 2
cm to more than 20 cm, have been discovered in the Lower Cretaceous of the
Ordos Plateau, Inner Mongolia. Each was measured and mapped, and enough
specimens were excavated to fill 180 crates. The majority of footprints
represent tridactyl, bipedal dinosaurs, and represent six different types,
comprising a "footprint fauna" remarkably similar to those from Early
Cretaceous sites in Korea, Japan and Canada. Numerous localities in the
Ordos have produced Early Cretaceous dinosaur skeletons, but depositional
environments favoring preservation of footprints were significantly
different from those preserving body fossils.

Bulanov, V.V., and Sennikov, A.G. 2006. The first gliding reptiles from the
Upper Permian of Russia. Paleontological Journal 40(suppl. 5):S567-S570.
ABSTRACT: Two new gliding reptiles from the Late Permian Kul'chumovo-A
locality (Orenburg Region), Rautiania alexandri gen. et sp. nov. and R.
minichi sp. nov., are described and assigned to the family Weigeltisauridae.
These finds substantially expand the knowledge of the morphology of this
group and suggest the climax state of terrestrial tetrapod communities of
eastern Europe in the pre-Triassic Time, which resulted in the development
of ecological niches not typical of earlier terrestrial vertebrate faunas.
Averianov, A.O., and Lopatin, A.V. 2006. Itatodon tatarinovi (Tegotheriidae,
Mammalia), a docodont from the Middle Jurassic of western Siberia and
phylogenetic analysis of Docodonta. Paleontological Journal 40(6):668-677.
ABSTRACT: Itatodon tatarinovi Lopatin et Averianov, 2005 is represented by
two lower molars and a lower molar fragment from the upper part of the Itat
Formation (Bathonian Stage) of the Berezovskii quarry (southern Krasnoyarsk
Region). Based on the presence of a pseudotalonid, bordered by the crests
a-b, b-e, e-g, and a-g, Itatodon is assigned to the endemic Asian family
Tegotheriidae. In this genus, the crest a-b is reduced and the thick lingual
cingulid is better developed than that of other docodonts. Phylogenetic
analysis of Docodonta shows paraphyly of Morganucodonta relative to
docodonts and independent development of the pseudotalonid in the
Tegotheriidae and the clade comprising Krusatodon, Castorocauda,
Cyrtlatherium, and Dsungarodon.

long-bodied lizard from the Lower Cretaceous of Japan. Palaeontology
49(6):1143-. doi: 10.1111/j.1475-4983.2006.00598.x.
ABSTRACT: Platynotan lizards underwent a dramatic Late Cretaceous radiation
into marine habitats. Beginning with small-bodied forms, the lineage
culminated with the mosasaurs, large predatory lizards with a world-wide
distribution in the Santonian-Campanian. Moreover, the marine squamate
radiations of the Cenomanian-Turonian are remarkable in having produced a
range of long-bodied, reduced-limbed swimmers (dolichosaurs, adriosaurs,
coniasaurs and limbed snakes) that seem to have thrived in the shallow
coastal environments of the Western Tethys region. Until now, none of these
long-bodied aquatic squamates has been recorded prior to the Cenomanian,
none has been recovered from a non-marine locality and none is known from
Asia. Here we describe a small, gracile, long-bodied mosasauroid lizard from
a swampy continental deposit in the Lower Cretaceous of Japan.
Nice name for the last one -- _Kaganaias_.
