Seals, the early years

It’s the moment you’ve all been waiting for… stem-pinnipeds at Tet Zoo. Or, probable stem-pinnipeds anyway. This minimum-effort post is brought to you on the back of work showing that pinnipeds (seals, sea lions and walruses) are monophyletic, not diphyletic, and that the taxa shown here – Potamotherium, Puijila and so on – really are [...]

A brief history of muskrats

African Climbing Mice and the Congo Link Rat

There’s an unusual group of African rodents that we rarely get to hear much about. Termed dendromurines, they’re named for Dendromus, the climbing mice, and mostly inhabit sub-Saharan Africa.

Confrontational behaviour and bipedality in deer

Confrontational behaviour and bipedality in deer

Now That’s a Wee Little Infographic

  53 million years old, and it may be the smallest mammal that has ever lived. Batodonoides vanhouteni was a shrew-like mammal that scientific illustrator Jen Christiansen has deftly described in this illustration.

The remarkable life appearance of the Woolly rhino

One of the Pleistocene mammals depicted without fail in popular books – encyclopedias of prehistoric life and the like – is the Woolly rhinoceros Coelodonta antiquitatis (the species name is written antiquus in many sources).
