Down to earth: therian mammals became more terrestrial towards the end of the Cretaceous

open access: yesPalaeontology, Volume 68, Issue 2, March/April 2025.
Abstract The end Cretaceous extinctions had a profound effect on mammalian diversity, especially on metatherians (marsupials and their extinct relatives). Could mammalian substrate preference have influenced differential survival patterns? The plant fossil record shows changing angiosperm leaf anatomy during the last ten million years of the Cretaceous

Threatened Mammals With Alien Populations: Distribution, Causes, and Conservation

open access: yesConservation Letters, Volume 18, Issue 1, January/February 2025.
ABSTRACT Many alien species are safe in their native ranges, but some are threatened. This creates a conundrum for conservation and invasion science. We analyzed the distributions, introduction pathways, threats, and conservation strategies of threatened mammals with alien populations globally.

A re-examination of the skeletal characters of Wynyardia bassiana, an extinct Tasmanian marsupial. [PDF]

open access: yes, 1930
Thirty years ago (P.Z.S. 1900, pp. 776-794) Sir Baldwin Spencer described and named the fossil Marsupial that had been brought to light by a fall of the cliff face at Table Cape, Tasmania.

Genome sequence of an Australian kangaroo, Macropus eugenii, provides insight into the evolution of mammalian reproduction and development. [PDF]

open access: yes, 2011
BACKGROUND: We present the genome sequence of the tammar wallaby, Macropus eugenii, which is a member of the kangaroo family and the first representative of the iconic hopping mammals that symbolize Australia to be sequenced.

Dental eruption in afrotherian mammals. [PDF]

open access: yes, 2011
BACKGROUND: Afrotheria comprises a newly recognized clade of mammals with strong molecular evidence for its monophyly. In contrast, morphological data uniting its diverse constituents, including elephants, sea cows, hyraxes, aardvarks, sengis, tenrecs ...

Of flippers and wings: The locomotor environment as a driver of the evolution of forelimb morphological diversity in mammals

open access: yesFunctional Ecology, Volume 38, Issue 10, Page 2231-2246, October 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The early diversification of tetrapods into terrestrial environments involved adaptations of their locomotor apparatus that allowed for weight support and propulsion on heterogeneous surfaces.

Cautionary tales on the use of proxies to estimate body size and form of extinct animals

open access: yesEcology and Evolution, Volume 14, Issue 9, September 2024.
Reconstructing the body size and form of extinct animals is of vital importance to our understanding of macroevolution and palaeontology. This is often done using anatomical proxies where extinct species are known only from fragmentary remains. However, there are many limitations influencing the selection of proxy taxa that are frequently overlooked ...

Modelling mammalian energetics: the heterothermy problem [PDF]

open access: yes, 2016
Global climate change is expected to have strong effects on the world’s flora and fauna. As a result, there has been a recent increase in the number of meta-analyses and mechanistic models that attempt to predict potential responses of mammals to ...

Proximal Humerus Morphology Indicates Divergent Patterns of Locomotion in Extinct Giant Kangaroos [PDF]

open access: yes, 2020
Sthenurine kangaroos, extinct “giant kangaroos” known predominantly from the Plio-Pleistocene, have been proposed to have used bipedal striding as a mode of locomotion, based on the morphology of their hind limbs.

Mammal coloration as a social signal

open access: yesJournal of Zoology, Volume 323, Issue 2, Page 114-128, June 2024.
Otherwise apparently cryptic mammals often have conspicuous patches of colour on distal regions of their body, possibly for signalling. To investigate ideas about communication within sociosexual contexts, we used a comparative dataset for 2726 terrestrial mammals to match the coloration and patterning of distal body areas (head, chest, rump, and tail)
