Tetrapod Zoology

One of the most interesting of anuran groups – in my humble opinion – is Hyloidea, also known as Hyloides….

Frogs and toads – collectively, the anurans – have been covered on numerous occasion across the history of Tetrapod Zoology though….

One of my favourite bird groups are the hornbills (or bucerotids), a spectacular, tropical group related to hoopoes, sadly in trouble due to the loss and deterioration of their habitats.

Among the most familiar of creatures in the entire pantheon of legend and mythology is the unicorn, an animal so ubiquitous that you won’t need me to provide a description of what it’s meant to look like.

Ever aiming to republish my squamate-themed articles from years back (specifically, from Tet Zoo ver 2), I here reproduce part of the multi-part series I released on geckos.

The enormous two-day event that was DinoCon 2026 – the second of our dinosaur-focused comic con-style meetings – is over, and wow.

Regular readers of Tet Zoo will – I hope – be familiar with taxonomic vandalism… Put simply, this is the phenomenon whereby rebellious individuals, typically working outside of institutional academia, seek to formally name or rename the organisms they’re…

Among the most handsome and striking of seabirds is the Razorbill.

Salamanders have been covered at Tet Zoo on numerous occasions, there being articles on newts and other salamandrids, plethodontids (lungless salamanders) of numerous sorts, and also ambystomatids (the group that includes the Axolotl and other mole salama…

Long-time readers of Tet Zoo will perhaps be aware of my efforts, beginning in 2012 or something like that, to depict in a montage the diversity of crocodylomorphs extinct and extant.

I feel the need to publish something new on rodents, and with no time to produce anything lengthy or all that complex, here are brief thoughts on one of my favourite rodent groups: voles!

I am extremely pleased to announce that my Dinosaurs: How They Lived & Evolved – the Natural History Museum, London’s flagship dinosaur book, co-authored with Professor Paul Barrett – is once again in print, once again as a new edition… Yes, this is the f…

It’s time for another article in my Tet Zoo Reviews Zoos series, and this time we look at a zoo in that troubled and terrifying nation known as the USA, specifically in the north-western state of Oregon… Caption: an Oregon Zoo montage, featuring animals s…

Inspired by the recent publication here of thoughts on the new Koumpiodontosuchus paper… and by other work, in prep… I felt it appropriate to rescue another article from the archives, specifically from ver 3.

Yes, the time is right to discuss the possibility of an expanded, ten-year-anniversary edition of my 2016/2017 Arcturus book Hunting Monsters… Prologue.

A very long article on a very small croc… Caption: a Koumpi montage, showing images by Mark Witton and from Barker et al. (2026).

Alien animals of any sort, by definition, cannot (in the phylogenetic sense) be tetrapods.

It’s time again to rescue another squamate-themed article from the Tet Zoo articles.

Last year saw the appearance of the long-awaited second edition of Dougal Dixon’s The New Dinosaurs (Dixon 2025).

It’s probably impossible to write about the history of fossil hominin discoveries in Africa and not discuss, or at least mention, the Leakeys… Caption: Mary Leakey’s 1984 book, the topic of the article here, with a few other relevant works in the backgrou…

Foot deformities are ubiquitous in urban pigeons.

Once again it’s that time of year, by which I mean… spawnwatch season, of course.

With – as of January 2026 – an impressive and respectable two decades of history behind it, Tetrapod Zoology surely has a notable footprint in terms of academic achievement and pop culture influence, right?
