Tetrapod Zoology

"It is - still - the best zoological blog out there, period"

Profile

Naish_profile_70_px.jpg With six years of phd work on theropod dinosaurs behind him, Darren Naish mostly spends long hours in the library, hunched over his laptop. But he gets out sometimes, and picks up litter and pursues exotic lizards across the British countryside, aiming all the while to publish his technical work on obscure Cretaceous dinosaurs. He also messes around with pterosaurs, swimming giraffes, British big cats and stuff like that. He has given up on the stupid idea of being a dedicated academic and ekes out a living as a technical consultant, editor and author. He can be contacted intermittently at eotyrannus (at) gmail dot com. For more biographical info go here.

Welcome, Dr M. P. Taylor

Category: community

As you'll know if you've already seen the announcement over at SV-POW!, my friend and co-author Mike P. Taylor successfully defended his Ph. D. yesterday: congratulations again, Mike. Mike's thesis was titled Aspects of the History, Anatomy, Taxonomy and Palaeobiology...

Ridiculous super-elongate, coiled windpipes allow some birds to function like trombones - - or is it violins?

Category: ornithology

Inspired by comments made following the emu dissection article from Monday, I got thinking about elongate tracheae in birds. As we'll see, this subject is fertile ground if you like serious weirdness and spectacular extremes [Trumpet manucodes shown here,...

Dissecting an emu

Category: ornithology

Back in 2006 my good friend Matt Wedel - who you may know better as one of the three SV-POWsketeers or as plain old Dr Vector - produced a short article on an emu dissection he participated in at...

Greek-nosed first-horned face and the 'bagaceratopids'

Category: Mesozoic dinosaurs

I never planned to do a whole week on ceratopsians: the initial idea was just to recycle some of those field guide texts in order to save a bit of time. But, oh well, Ceratopsian Week took on a...

Ceratopsian dinosaurs: cheeky or beaky?

Category: Mesozoic dinosaurs

What with yesterday's article on an 'alternative look' for ceratopsians, here's another one. The image used here (again, a powerpoint slide from one of my talks) is pretty self-explanatory, and I use it here because Witmer and colleagues (Papp 1997,...

A very alternative view of horned dinosaur anatomy

Category: Mesozoic dinosaurs

One of the most distinctive features of ceratopsian dinosaurs is the conspicuous bony frill, formed from the parietal and squamosal bones, that projected backwards (and sometimes upwards too) from the rear margin of the skull. Typically decorated around their edges...

Zuniceratops and the early acquisition and alleged dimorphism of ceratopsian brow horns

Category: Mesozoic dinosaurs

So far we've looked at leptoceratopsids and chasmosaurine ceratopsids. This time, it's the turn of the basal ceratopsoid Zuniceratops. If these terms are giving you grief, a cladogram showing a few of them is below......

No-one talks about Anchiceratops, boo hoo

Category: Mesozoic dinosaurs

Another obscure ceratopsian from the defunct field guide project: for the back story go here and here. A distinctive chasmosaurine similar in size to a large rhino (total length approximately 3.5 m), Anchiceratops ornatus was a heavily built species with...

Udanoceratops tschizhovi, the basics

Category: Mesozoic dinosaurs

Once more, I'm going to start recycling some of those dinosaur texts written for the defunct field guide (for the back-story on that project see the ornithomimosaur article here). This time round, I'll get through some of the ceratopsians...

Mosasaurs might have used the same microscopic streamlining tricks as sharks and dolphins

Category: herpetology

Thanks to Monday's article on the unusual African mosasaur Goronyosaurus, I will admit that I was - quite seriously - considering doing a 'mosasaur week', perhaps even a 'weird mosasaur week'. Alas, I have not had the time. However:...
