Agamids are a widespread, diverse iguanian lizard group that I have a special fondness for and consequently have featured several times on Tet Zoo (see links below).
TURTLES! A section of the montage that's being prepared for the Tet Zoo Big Book (larger version viewable at my patreon). Image in-prep, by Darren Naish.
Time again to look at some recently published books relevant to the TetZooniverse - book on palaeoart, primates, bats, and crocodylians...
Crocodiles, alligators and gharials are the modern members of a far grander, far more diverse clade of archosaurian reptiles termed Crocodylomorpha.
What with all the monitor-themed goodness around these parts lately (see links below), it seems only fitting that I provide a re-vamped, substantially updated version of this Tet Zoo ver 2 classic (originally published in September 2007).
Diploglossines – popularly called galliwasps – are an extant group of anguid lizards that inhabit South and Central America as well as the Antilles (Anguidae is the group that includes alligator lizards, slow-worms, glass lizards and kin). Most galliwasps are robust-bodied lizards with normally proportioned, complete limbs. A reduced digit count and reduced limb size is, however, present in the obscure taxa Ophiodes, Sauresia and Wetmorena. The vast majority of species are included within Celestus (with about 30 species) and Diploglossus (with about 17 species).
In recent articles I've made an effort to review the skinks of the world and today - it's a momentous occasion - we see the last part of this series.
Time for more Australian agamids, or amphibolurines, or dragons, whichever you prefer. Last time round, we looked at the water dragons, Moloch and a few other taxa, meaning that all thats left to get through is the remainder.
Terror skinks, social skinks, crocodile skinks, monkey-tailed skinks… it's about skinks (skinks part II)
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.
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.
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.
I said in the previous Tet Zoo article on monitor lizards that I really wanted to cover the prasinoids; that is, the arboreal tree monitors of New Guinea, Cape York Peninsula and various of the islands surrounding these areas.
In the previous article, we looked at parsley frogs or pelodytids - a small and conservative lineage within the anuran clade Pelobatoidea (also known as Anomocoela, and commonly as the spadefoot toads).
As you'll know if you've been following Tet Zoo for any length of time, I've been slowly working my way through the toads of the world for the past few years - yes, all of them, more or less.
One of my favourite ichthyosaurs is the generally large, archaic, long-snouted Temnodontosaurus, and if you have an especially good memory youll recall it being mentioned here and there on Tet Zoo over the years (see links below).
I'm feeling the urge to blog about lizards. So, today I'd like to talk about the Aprasia species, a group of short-tailed, near-limbless gekkotans that belong to the Australian Pygopodidae family, the so-called flapfoots, flap-footed lizards or pygopods.
The presence in Europe of plethodontids is unusual enough (albeit well known), but a major surprise in plethodontid research was the discovery of an Asian member of the group, the Korean crevice salamander Karsenia koreana Min et al., 2005. Plethodontid expert David Wake described its finding as “the most stunning discovery in the field of herpetology during my lifetime”...
Thanks to that recent Tet Zoo article about American spadefoot toads and their tadpoles, I've had visions in my mind of drying ephemeral pools in hot, arid environments, crammed with crowded, gasping tadpoles.
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.
Today: LIZARDS. Even better: obscure Australian agamids, or dragon lizards, or dragons, if you prefer. Ive written about agamids a few times on Tet Zoo but have never gotten to say much (if anything) about the Australian radiation, grouped together into the clade Amphibolurinae.
