Why were elaborate cranial ornaments so diverse and so widespread in pterosaurs and Mesozoic dinosaurs? These structures – grouped together here as ‘cranial crests’ – vary markedly in form and position: they range from the semi-circular blades and keels present at the snout-tips of ornithocheiroid pterosaurs to the hollow tubes, fans and plate-like crests of lambeosaurine hadrosaurs and the bony frills of ceratopsians...
You’re reading a blog. This almost guarantees the fact that you’re a staunch supporter, and fan, of open-access publishing. Many of us who publish technical research really do try to publish in open-access venues as often as possible...
I wanted to use this photo because it’s weird and interesting, not because I have anything particularly insightful to say about softshell turtles. The animal shown here is a Florida softshell Apalone ferox that I photographed in captivity earlier in 2011...
Demands of work and all that mean that I need to sign off for Christmas now, so no time to blog about sauropod biology, toads, tadpoles, Cretaceous crocodilians (Salisbury & Naish 2011), mutual sexual selection in ornithodirans (Hone et al ...
Sauropod dinosaurs are – in my somewhat biased opinion – among the most fascinating tetrapods that ever evolved. Exceeding all other terrestrial animals by an order of magnitude and famous for their extreme and often ridiculous necks, they were also remarkable in possessing an often elaborate degree of skeletal pneumatisation...
Welcome to part II of the Tet Zoo cetacean clearing house. With stem-cetaceans (‘archaeocetes’) and mysticetes out of the way (go here for part I), we come to odontocetes.
It’s apparently a good idea in scientific blogging to produce ‘clearing house’ blog articles every now and again: that is, articles that include links to all of your other articles on a given subject...
Finally, I have in my possession a copy of English Wealden Fossils , the massive, significant and long-awaited new volume published by the Palaeontological Association as part of its Field Guide to Fossils series (this is number 14 in the series)...
Ok, in keeping with what I said in the previous article (the review of Gerhard Maier’s African Dinosaurs Unearthed ), here’s the second of those reviews on “outstanding new volumes ...
Over the past few years, three really outstanding new volumes have been published on the history of Mesozoic dinosaur research and discovery. I’ve been able to read and review all of these works and have really enjoyed doing so...
