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 [...]..
Crocodiles, alligators and gharials are the modern members of a far grander, far more diverse clade of archosaurian reptiles termed Crocodylomorpha.
While on a family holiday recently I visited Dan yr Ogof, the famous National Show Cave for Wales. Besides being interesting for the expected geological and speleological reasons, Dan yr Ogof is set within landscaped gardens that, bizarrely, feature one of Europe's largest `dinosaur parks'...
Regular readers of Tet Zoo might know that I've published extensively on the theropod dinosaurs of a famous and much-studied Lower Cretaceous rock unit known as the Wealden Supergroup.
There have never been enough primates on Tet Zoo. That isn't because I'm not interested in primates, nor because I don't think about primates, or look at primates, that much… in fact, I probably think about, and look at, primates more than I do any other group of animals… it's simply because - as is [...]..
Ratites in trees: the evolution of ostriches and kin, and the repeated evolution of flightlessness (ratite evolution part II)
Regular Tet Zoo readers will recall the article from March on ratite and tinamou evolution. Ratites, just in case you don't know, are the flightless kiwi, ostriches, rheas, emus and so on, while tinamous are their diminutive, flight-capable, superficially pheasant-like close relatives...
This isn’t a normal scheduled blog post; instead, it concerns some announcements. Firstly, TetZooCon – the first ever Tetrapod Zoology Convention – is go.
In a further effort to relieve Turtle Guilt (see the previous turtle-themed Tet Zoo article), I give you the following article devoted wholly to kinosternids, an exclusively American group of about 25 species of seemingly mundane and unspectacular turtles...
There's been a bit of a monitor lizard thing going on here for the past few months: articles have covered Australian goannas, the Komodo dragon Varanus komodoensis, Dumeril's monitor and Timor and Peachthroat monitors, and the `prasinoid' tree monitors...
