Profile
With six years of tedious phd work on theropod dinosaurs behind him, Darren Naish stares longingly from his office window at the birds outside and wonders: why did I bother? He pursues exotic lizards and feral cats across the British countryside, occasionally prizes the skeletal jaws from hedgehog corpses, and aims to publish his technical work on obscure Cretaceous dinosaurs. He remains desperately in quest of an academic job that'll last more than a month, and - with a background in TV research, e-learning development, academic editing, popular writing, teaching, landscape gardening, parenting and the wonderful world of retail - he still holds out hope of becoming a dedicated academic. He can be contacted intermittently at eotyrannus (at) gmail dot com. For more biographical info go here.

There is no doubt among biologists that the world's 6000-odd amphibian species are in trouble: about 1600 are classified as 'threatened', around 430 are listed as 'critically endangered', and at least 100 species - probably more than 160 - appear to have become extinct within the last couple of decades. This isn't because amphibians are crap and hated by god, it's because the results of our actions are killing them. What can be done?

The fossil record convincingly demonstrates that pterosaurs became extinct at the end of the Maastrichtian in the Late Cretaceous (65 million years ago). However, sightings of unusual winged animals around the world have led some people to suggest that pterosaurs might have survived to the present. How realistic are these claims, and can they be taken seriously?

Thanks to everyone for their comments on the previous article about island-endemic otters and canids. I was going to add a brief response to the comments section, but eventually the comments reached the length you see here, hence my...

The affinities and origin of the Warrah have been the subject of much discussion. Its tameness, its presence on the Falkland Islands (a place devoid of other terrestrial mammals), and several of its morphological features (white tail-tip, enlarged frontal sinuses and wide muzzle) have led some workers to argue that it a domesticated form bought over to the islands by the Yahgan people.

Like the moose, the Eurasian lynx is not a prehistoric animal in wild Britain: we now know that it was still here until about 1500 years ago, so the argument that it has only been extirpated recently and really should still be here is a good one. A feasibility project led Hetherington & Gorman (2007) to conclude that Britain has enough space and wild animal prey to accommodate introduced lynxes, and there is much discussion as to whether such a project should go ahead.

Near-complete pliosaur skeletons indicate that the skull was about 17% of total body length, suggesting that the whole animal might have approached 18 m. As Naish et al. (2001) said: 'The caveat, however, is that this assumes that this skull-to-total-length ratio remains constant throughout growth, and it may well not do'. And, yes, it's specimens like this that led to the totally speculative 25 m given for Liopleurodon in the BBC's Walking With Dinosaurs...

Though imagined by some to have been a sort of cookie-cutter that took chunks out of ammonites or big vertebrates, Simolestes is interpreted by Leslie as a cephalopod specialist and indeed the Dogsthorpe specimen contained a large number of cephalopod hooklets...
