The New World crocodile assemblage: crocodiles part VII – last in series!

American-crocodile

A momentous thing is about to happen. Take a deep breath and prepare yourself. Today is the day when… I finish my series of articles on the crocodiles of the world. As you’ll recall if you read the previous six parts of this series (all of which are linked to below), I’ve managed so far [...]

Quetzalcoatlus: the evil, pin-headed, toothy nightmare monster that wants to eat your soul

Giovanni Caselli's 1975 Demon Quetz, the image that started the meme.

Regular readers of Tet Zoo will be familiar with two topics I’ve covered on and off over the years: azhdarchid pterosaurs, and palaeoart memes. Azhdarchids were mostly large to gigantic, long-skulled Cretaceous pterosaurs, noted for their enormous wingspans (up to 10 m or so in the case of Quetzalcoatlus from the USA and Hatzegopteryx from [...]

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 [...]

Daisy’s Isle of Wight Dragon and why China has what Europe does not

We’ve named another new pterosaur! Once again, the open-access online journal PLOS ONE hosts a paper that I and colleagues (Martin Simpson and Gareth Dyke, both of the University of Southampton) have published on a new taxon (Naish et al. 2013). This is the third paper I’ve published in PLOS ONE so far this year, and [...]

Crocodiles of Africa, crocodiles of the Mediterranean, crocodiles of the Atlantic (crocodiles part VI)

The Tet Zoo crocodile series is not yet finished, and here we embark on part VI in the series (see below for links to previous parts). This time, we come to the Nile crocodile lineage, and I refer here to a ‘lineage’ rather than to a species since there’s now good evidence that C. niloticus [...]

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 [...]

Awesome sea-going crocodyliforms of the Mesozoic

The Mesozoic was not a ‘dinosaurs-only theme park’. Numerous other tetrapod lineages were around as well, and there was enough ‘ecospace’ for members of at least some of these groups to evolve giant size and macropredatory lifestyles, and even to dominate certain sections of the Mesozoic world. It’s well known in particular that this was [...]

In pursuit of Early Cretaceous crocodyliforms in southern England (part II): of Vectisuchus and Leiokarinosuchus, Bernissartia and the hylaeochampsids

In the previous article we looked at Wealden goniopholidids, focusing in particular on the new taxa named by Steve Salisbury and myself in the review of Wealden crocodyliforms we published last year (Salisbury & Naish 2011). Having gotten some of the relevant taxa out of the way, we now need to crack on and get [...]

In pursuit of Early Cretaceous crocodyliforms in southern England: ode to Goniopholididae

Regular readers of Tet Zoo might know that much of my specialised technical research centers around the dinosaurs, pterosaurs and other fossil reptiles of the Wealden Supergroup. What is the Wealden Supergroup? It’s the name given to a series of mudstones, siltstones and sandstones, deposited across the floodplains, lagoons and estuaries of south-eastern England during [...]

The Crocopocalypse is upon us

I’ve been drawing crocodylomorphs. Lots of them. Crocodylomorpha, as if you need reminding, is the archosaur clade that essentially includes all archosaurs traditionally dubbed ‘crocodilians’: the living crocodiles, alligators and gharials and all their fossil relatives. These animals were hugely diverse in the past, and hopefully you can get some idea of that diversity (by [...]
