Tetrapod Zoology

Archives for May, 2010

It’s just too good not to mention. Yesterday I re-posted an old article about manatee dispersal across the Atlantic. And on the same day came news that a living Grey whale Eschrichtius robustus has been seen off Herzliya Marina, Israel, meaning that at least one living, breathing Grey whale is currently swimming around in the…

No time for anything new (working on a book chapter and putting the finishing touches to the Tet Zoo book), so here’s this, from the archives. NOT properly updated, so please be aware that it’s more than four years old…

My dinosaur colouring book # 2

Another one. Identify the creatures (all from the Barremian Wessex Formation of the Isle of Wight, England) – possibly more difficult this time! Remember that some of the animals are in ‘historic guise’, so are portrayed very much inaccurately. And no cheating, as labelled versions of this picture have been published before (in the Japanese…

Back to gekkotans: time to look at digits. Geckos are well known for the ability of many species to cling to vertical surfaces, and even to ceilings. In fact, this is usually the one thing about geckos that everyone knows. The powers of gecko adhesion are such that geckos can support their entire weight while…

But before you get too excited I should point out that the taxon concerned is not exactly new. It was first named in 1908 and has previously been regarded (without exception) as a ‘subspecies’.

Giraffe-necked giant tortoises

Until recently the Mascarenes were home to an endemic radiation of giant tortoises, the Cylindraspis species. These were entirely separate from the better known, more ‘typical’ Mascarene giant tortoises grouped together in Dipsochelys or Aldabrachelys (Austin & Arnold 2001). Easily the most remarkable Cylindraspis tortoise was C. vosmaeri from Rodrigues, sometimes called the Rodrigues saddle-backed…
