Abstract Two female woolly mammoth neonates from permafrost in the Siberian Arctic are the most complete mammoth specimens known. Lyuba, found on the Yamal Peninsula, and Khroma, from northernmost Yakutia, died at ages of approximately one and two months, respectively. Both specimens were CT-scanned, yielding detailed information on the stage of development of their dentition and skeleton and insight into conditions associated with death. Both mammoths died after aspirating mud. Khroma's body… 
Virtual paleontology: computer-aided analysis of fossil form and function
Three-dimensional imaging techniques allow poorly understood or previously unknown anatomies of fossil plants, invertebrates, and vertebrates, as well as microfossils and trace fossils, to be described in much greater detail than formerly possible, and are applicable to a wide range of preservation types and specimen sizes.
Brain evolution in Proboscidea (Mammalia, Afrotheria) across the Cenozoic
The authors' analyses support that, in general, brain size and body mass co-evolved in proboscideans across the Cenozoic; however, this pattern appears disrupted by two instances of specific increases in relative brain size in the late Oligocene and early Miocene.
A New Method of Estimating Brain Mass Through Cranial Capacity in Extinct Proboscideans to Account for the Non-Neural Tissues Surrounding Their Brain
This data set suggests that a comparatively small brain is likely primitive for Proboscidea and that the representatives of the clade Elephantimorpha have inherited their large brain from their last common ancestor.
Comparative brain morphology of Neotropical parrots (Aves, Psittaciformes) inferred from virtual 3D endocasts
The results indicate that there are two conspicuously distinct brain morphologies, one considered walnut type (quadrangular and wider than long) and the other rounded (narrower and rostrally tapered), and the endocranial morphology of the Psittaciformes as a whole is distinctive relative to other birds.
Nonpyrogenic charring of Late Pleistocene large mammal remains in northeastern Russia
Mammal remains preserved in the permafrost zone often bear traces of postmortem transformations, reflecting aspects of the palaeoenvironment and the processes that took place during the accumulation
The Volchia Griva mineral oasis as unique locus for research of the mammoth fauna and the late Pleistocene environment in Northern Eurasia
This paper describes the results of research at Volchia Griva, the largest site in Asia containing mammoth fauna in situ. It is situated in the south of the West Siberian Plain in the Baraba


Early tooth development, gestation, and season of birth in mammoths
The intestinal contents of a baby Woolly mammoth (Mammuthus primigenius Blumenbach, 1799) from the Yuribey River (Yamal Peninsula)
Examination showed that the baby mammoth had no internal lesions and had a well developed subcutane ous fat, and a sample of the large intes tine contents was taken and comprehensively analysed to reconstruct the natural conditions exist ing during the lifespan of thebaby mammoth and determine the cause of its death.
Holocene dwarf mammoths from Wrangel Island in the Siberian Arctic
The dwarfing of the Wrangel mammoths is interpreted as a result of the insularity effect, combined with a response to the general trend towards unfavourable environment in the Holocene.

The significance of vivianite in archaeological settings
Vivianite is a bluish mineral sometimes encountered in archaeological deposits. It is notable for its tendency to change color from white or grayish to blue on exposure to air. Vivianite requires
Complete Columbian mammoth mitogenome suggests interbreeding with woolly mammoths
Though limited, the data suggest that the two species interbred at some point in their evolutionary histories, and the use of next-generation sequencing technologies holds promise in obtaining such data, even from non-cave, non-permafrost Pleistocene depositional contexts.
