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

TLDR
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

TLDR
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.

TLDR
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.

A New Docodont (Docodonta, Mammalia) from the Middle Jurassic of Siberia

TLDR
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.

NEW DOCODONTANS FROM THE MIDDLE JURASSIC OF SIBERIA AND REANALYSIS OF DOCODONTA INTERRELATIONSHIPS

TLDR
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.

New teeth of allotherian mammals from the English Bathonian, including the earliest multituberculates

TLDR
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.
