Brilliant Brazilian spinosaurids

Rio-May-2013-DNPM-Angaturama-skeleton-head-end-right-lateral-600-px-tiny-May-2013-Darren-Naish-Tetrapod-Zoology

You liked the photo of the brilliant Angaturama skeletal mount, right? Photographed at the Museu Nacional, Rio de Janeiro, the mount shows Angaturama limai – a spinosaurine spinosaurid – carrying the skeleton of an anhangeurid pterosaur. Here are some more views of the same display… The behavioural interaction you see here was not just invented in [...]

In Rio for the 2013 International Symposium on Pterosaurs

I love academic conferences, I love pterosaurs, and I love South America. So, as predicted, I very much enjoyed the International Symposium on Pterosaurs I just attended: it was the sixth symposium devoted specifically to pterosaurs, and was held at the Museu Nacional/UFRJ (= Universidade Federal do Rio de Janeiro), Rio de Janeiro. Yes, an [...]

Malawania from Iraq and the Cretaceous Ichthyosaur Revolution (part II)

Bob Nicholls's excellent life restoration of Malawania, coloured by C. M. Kosemen. Thanks to both artists for their excellent and speedy work.

Tet Zoo readers with supernatural memories will doubtless recall the January 2012 article ‘Rigid swimmer’ and the Cretaceous Ichthyosaur Revolution (part I) [link below]. I’ll refresh your memory by telling you that the article was all about the PLoS ONE paper on Acamptonectes, a Cretaceous ophthalmosaurid ichthyosaur from the UK and Germany described by Valentin [...]

Crocopocalypse exposed in public for the first time!

Tet Zoo regulars will remember the detailed montage I’ve produced that hopefully gives some idea of crocodylomorph diversity (Crocodylomorpha = the archosaur clade that includes modern crocodylians and all taxa closer to them than to croc-branch members of Archosauria like the aetosaurs and rauisuchians. Crocodylomorpha is basically equivalent to ‘Crocodilia’ of tradition; most members of [...]

Scenes from the Lyme Regis Fossil Festival

Over the last few days, I and my friends and colleagues from the University of Southampton’s vertebrate palaeontology research group visited Lyme Regis for the 2013 Fossil Festival, a big, fun event attended by 1000s of people and by most palaeontologically- and geologically-oriented people in the southern half of the UK. There are stalls and [...]

Trematosauroids, those gharial-snouted, marine temnospondyls

Long-time Tet Zoo readers will know of my various efforts to get through all the temnospondyl lineages. Alas, I just haven’t been able to finish this grand project due to my getting stuck somewhere round about dissorophoids (see below for links to previous Tet Zoo temnospondyl articles). In frustration, here’s a section from late in [...]

A new azhdarchid pterosaur: the view from Europe becomes ever more interesting

Another day, another new paper out in PLOS ONE. Today sees the publication of the new azhdarchid pterosaur Eurazhdarcho langendorfensis Vremir et al., 2013, a new species from the Upper Cretaceous Sebeş Formation of the Transylvanian Basin in Romania (Vremir et al. 2013). ‘Vremir’ is my good friend Mátyás Vremir; he worked together with Alex [...]

Plesiosaurs and the repeated invasion of freshwater habitats: late-surviving relicts or evolutionary novelties?

There are quite a few life restorations of leptocleidids. This shows the Australian taxon Leptocleidus clemai, by John Long. From Cruickshank & Long (1997). I don't think the flippers are depicted well.

Time to talk about another recently published paper I was involved in: this time, the looooong awaited Journal of Systematic Palaeontology paper ‘A new leptocleidid (Sauropterygia, Plesiosauria) from the Vectis Formation (Early Barremian-early Aptian; Early Cretaceous) of the Isle of Wight and the evolution of Leptocleididae, a controversial clade’ (Benson et al. 2012a). Wow, what [...]

Tet Zoo Christmassy wishes, 2012

I knocked this up in a hurry yesterday but I think it’s good enough to share publicly. The pristichampsine is meant to be trotting along at speed, and that explains why its hat is falling off. Have a great Christmas and New Year – here’s to 2013. 2012 was a crazy year for me (annual [...]
