Welcome to the second part of the ‘What’s with all these new chameleon names?’ series. In the previous article, we looked at the fact that the ‘two genera system’ widely in use prior to the 1990s started to fall apart during the 1980s; we also looked specifically at the chameleon genera Rhampholeon and Rieppeleon. This time round—surprise surprise—we look at... more chameleons
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).
Time again to look at some recently published books relevant to the TetZooniverse - book on palaeoart, primates, bats, and crocodylians...
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.
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).
Crocodiles, alligators and gharials are the modern members of a far grander, far more diverse clade of archosaurian reptiles termed Crocodylomorpha.
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.
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.
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).
Sirens build nests, have beaks, eat plants and have a history of "size shuffling"--they're incredible!
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”...
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).
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.
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.
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.
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.
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.
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).
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.
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.
