A selection of crested non-avialan theropod and ornithischian dinosaurs. Diagrams by Dave Hone. Why were elaborate cranial ornaments so diverse and so widespread in pterosaurs and Mesozoic dinosaurs?
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 .
Diplodocid sauropods, artwork by Mark Witton. Sauropod dinosaurs are – in my somewhat biased opinion – among the most fascinating tetrapods that ever evolved.
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.
Whole cetacean cladogram, from Geisler et al. (2011). Click to enlarge (preferably: download the paper - it's open access). 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.
