The Artful Amoeba

Alpine Toads and the Chytrids that Love Them

OLYMPUS DIGITAL CAMERA

When you read a story, you may occasionally wonder what the reporter went through to get it. About a month ago I arose at 5 a.m. to  accompany two wildlife biologists and three fisheries volunteers into the high country of Colorado in order to report a story that came out in High Country News this [...]

Road Kill So Perty You Can Bring It Home To Ma

13-037FEATURE

Most people swerve around road kill in hopes of avoiding the gore, or worse, the dreaded thwump that indicates you added your treadmarks to the list of said road kill’s insults. But a few crazy people will screech to a halt to see what got hit. Two of these folks just happen to be researchers, [...]

‘Shanklin croc’ and the dawn of the tethysuchian radiation

Hey, Darren, how’s it going with that plan to discuss all the fossil crocodylomorph groups? Huh? Well, ha ha, it ain’t going so well… goddam life getting in the way of my blogging. But the publication of a new technical paper, co-authored by myself and colleagues and led by marine crocodylomorph guru Mark Young, gives [...]

Terror skinks, social skinks, crocodile skinks, monkey-tailed skinks… it’s about skinks (skinks part II)

Criminally simplified depiction of lygosomine skink phylogeny (topology mostly based on Pyron et al. 2013). Photos (top to bottom) by Wolfgang Wuster, H. Zell, $Mathe94$, Benjamint444 (all CC BY-SA 3.0), Mark Stevens (CC BY 2.0), W.A. Djatmiko, S. Caut et al. (both CC BY-SA 3.0).

October 2014 continues – for no particular reason at all – to be Lizard Month here at Tet Zoo and right now it’s time for more skinks. The previous article is a sort of general introduction to the group as well as a review of the limbless acontiines/acontids and weird feylinines. This time, we move [...]

Skinks skinks skinks (part I)

A Tiliqua montage. At top: Blotched blue-tongue (T. nigrolutea) (photo by Benjamin444, CC BY-SA 3.0). Below: A Shingleback (T. rugosa) (photo by Jarrod, CC-BY-2.0).

Skinks (properly Scincidae… though read on) are one of the most successful of squamate groups, accounting for approximately 1500 species – in other words, for about 25% of all lizards. Skinks occur on all continents (except Antarctica) as well as on numerous island groups. Extant species range from less than 10 cm in total length [...]

Racerunner lizards of the world unite

Racerunners as geopolitical icons. Steppe-runners (E. arguta) on stamps produced by Kyrgyzstan and Moldova. Images in public domain.

Today we’re here because of the lacertid lizards, the Old World clade that includes Eurasian wall lizards, green lizards, fringe-toed lizards and a great number of less familiar species groups that rarely get much attention outside of the specialist literature. Yes, as you might have realised if you’re a long-term and/or regular reader, this is [...]

Neat news from the TetZoo-sphere

"Tapirs sometimes walk on the bottom of lakes and rivers". Oh really? Yes, really.

Here are some amazing things that me and my friends have been talking about lately. They all concern fascinating discoveries or insights into unusual aspects of tetrapod behaviour. We’ll start with my current obsession: the short bit of underwater footage (16 seconds long) that shows an adult Lowland tapir Tapirus terrestris ‘walking’ (at great speed) [...]

Simbirskiasaurus, Pervushovisaurus and their very, very strange nostrils: the Cretaceous Ichthyosaur Revolution (part III)

Life reconstruction of Platypterygius australis by Frank Knight; the species concerned is one of the best known of species included within Platypterygius. It was a large, robust-jawed, long-paddled ophthalmosaurid with numerous stout teeth. Stomach contents confirm a generalised diet of invertebrates and vertebrates.

The event you’ve all been waiting for is here: Simbirskiasaurus and Pervushovisaurus have been resurrected, and we’re all wondering what the hell’s going on with their absurd, complex nostrils. Yes, welcome to another instalment in the long-running, slow-burning series of Tet Zoo articles on Cretaceous ichthyosaur diversity. In previous articles we’ve looked at the 2012 [...]

For the love of crocodylomorphs

Brilliant life restoration of the recently described Cretaceous baurusuchid Aplestosuchus (with another crocodylomorph - a sphegesaurid - in its mouth), by Rodolfo Nogueira.

Crocodiles, alligators and gharials are the modern members of a far grander, far more diverse clade of archosaurian reptiles termed Crocodylomorpha. It’s gradually becoming better known that, in additional to including amphibious, long-skulled taxa like the living ones, the group encompasses an incredible array of terrestrial and semi-terrestrial omnivores, herbivores, carnivores and insectivores. Some had [...]

Model salamanders, in a cave

Life-sized Fire salamander model, encountered in one of the Dan yr Ogof caves, Brecon Beacons National Park, Wales.

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’. Great plastic models of tyrannosaurs, sauropods and all manner of [...]

Musk turtles and mud turtles: look boring, are secretly hyper-diverse

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. Kinosternidae includes turtles that go by two common names: musk turtles (Sternotherus) and mud turtles (Kinosternon)… [...]

Monitor musings, varanid variables, goannasaurian goings-on… it’s about monitor lizards

Current version of the monitor montage. Image by Darren Naish.

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. In ‘spare’ time, I’ve been working on the montage you see here, designed to depict a [...]
