Tashtykia primaeva gen. et sp. nov. and Tagaria antiqua gen. et sp. nov. (Multituberculata incertae sedis) are described based on isolated teeth from the Middle Jurassic (Bathonian) Itat Formation from the Berezovsk coal mine in Krasnoyarsk Territory, Western Siberia, Russia. Tashtykia primaeva gen. et sp. nov. is characterized by a P5 with three rows of cusps (cusp formula 2B:4M:6L) and a high sectorial p4 with two triangular lobes, five serrations associated with labial and lingual ridges… 
New data on Barbatodon oardaensis Codrea, Solomon, Venczel & Smith, 2014, the smallest Late Cretaceous multituberculate mammal from Europe
Surprisingly, after the Early Cretaceous taxonomic diversity recorded in Europe, which probably is largely an artifact of inadequate taxonomy and inflation of taxa, multituberculate mammals became
A New Mammal Skull from the Late Cretaceous of Romania and Phylogenetic Affinities of Kogaionid Multituberculates
Despite their Maastrichtian age, the very simple and conservative dental morphology of these Romanian kogaionids suggests that they originated from an eobaatarid-like ancestor dispersing from Asia or possibly already existing in Europe between the Barremian and Albian, 40 to 55 Ma earlier.
Second specimen of Corriebaatar marywaltersae from the Lower Cretaceous of Australia confirms its multituberculate affinities
A second specimen of the Australian cimolodontan multituberculate Corriebaatar marywaltersae from the same locality (Flat Rocks) as the holotype and previously only known specimen, reveals far more

ABSTRACT The Kilmaluag Formation on the Isle of Skye, Scotland, provides one of the richest Mesozoic vertebrate fossil assemblages in the UK, and is among the richest globally for Middle Jurassic
Tip dating supports novel resolutions of controversial relationships among early mammals
This analysis supports an Early Cretaceous age for Juramaia, but similar analyses on 12 other mammaliaforms from the Yanliao Biota return the correct, Jurassic age, showing that analyses incorporating stratigraphic data can produce results very different from other methods.


Haramiyidan Mammals from the Middle Jurassic of Western Siberia, Russia. Part 1: Shenshouidae and Maiopatagium
Three new euharamiyidan taxa are described based on isolated teeth from the Middle Jurassic Itat Formation of the Berezovsk coal mine in Krasnoyarsk Territory, Western Siberia, Russia based on a premolariform p4, in which the main cusp and basined heel are surrounded by two rows of cusps.
Two new mammalian teeth (Multituberculata and Peramura) from the Lower Cretaceous (Barremian) of Spain
Two new mammalian taxa from Poca, Galve (Teruel) are described: Lavocatia alfambrensis gen. nov., sp.
The Oldest Dryolestid Mammal from the Middle Jurassic of Siberia
ABSTRACT Anthracolestes sergeii, gen. et sp. nov., based on three isolated lower molars and several edentulous dentary fragments from the Middle Jurassic (Bathonian) Itat Formation at Berezovsk
Late Jurassic multituberculate mammals from Langenberg Quarry (Lower Saxony, Germany) and palaeobiogeography of European Jurassic multituberculates
ABSTRACT The Late Jurassic (late Kimmeridgian) multituberculate assemblage from the Langenberg Quarry in Northern Germany includes Paulchoffatiidae indet., the pinheirodontid Teutonodon
A New Docodont (Docodonta, Mammalia) from the Middle Jurassic of Siberia
This locality was studied by joint expeditions of the Paleontological Institute of the Russian Academy of Sciences and Krasnoyarsk Regional Museum in 2001 and by St. Petersburg and Tomsk state universities in 2003 and yielded fragmentary mammal specimens, including a molar of a new docodont, which is described below.
A new phylogenetic analysis demonstrated that Itatodon is the most basal known docodontan, and the Middle Jurassic mammals of Laurasia are now known from three principal assemblages: Forest Marble in England, Balabansai in Kyrgyzstan, and Itat in West Siberia.
The first multituberculate mammal from India
The presence of a new multituberculate mammal, Indobaatar zofiae gen. et sp.
The first Haramiyid (Mammalia, Allotheria) from the Jurassic of Russia
A new haramiyid species from the Middle Jurassic of Siberia is described; it is represented by isolated upper and lower teeth.
New teeth of allotherian mammals from the English Bathonian, including the earliest multituberculates
New material and additional morphological details of a rare and phylogenetically significant large fossil snake, Wonambi naracoortensis Smith, 1976, are described from Pleistocene and Pliocene cave deposits in southern South Australia and show that differences between snakes and other squamates have sometimes been overstated.
