Updates ... and SVP Romer Prize

I've just noticed that it's been about four months since I posted my last blog entry...It is rather scary how time seems to fly even when you are not necessarily having fun...

Anyway, I thought I might as well advertise this. In the upcoming SVP at Bristol, I shall be giving a talk in the Romer Session:

Myology and functional morphology of biting in avian and non-avian dinosaurs.

It's mostly about non-avian theropods now but I have a couple of birds in there for comparison; I don't know now why I emphasised birds in the title, I could have just said dinosaurs... Perhaps it's because I made much of my myological observations in birds (but also a few crocs).

I shan't write too much about it here, but the work is basically a suped-up version of my Masters thesis from way back, almost six years now... I had to come up with a way to rescue the concept if not the work, after I'd realised I had some fatal flaws in the basic assumptions of the calculations in my Masters work, and it took nearly six years to perfect.

Thanks guys. I think my talk should be of interest to a number of people.

I hope you enjoy England, Zach!

The difference between Lion and Tiger skulls

A quick divergence from my usual dinosaurs, and I shall talk about big cats today. This is because to my greatest delight, I had discovered today a wonderful book. It is called The Felidæ of Rancho La Brea (Merriam and Stock 1932, Carnegie Institution of Washington publication, no. 422). As the title suggests it goes into details of felids from the Rancho La Brea, in particular Smilodon californicus (probably synonymous with S. fatalis ), but also the American Cave Lion, Panthera atrox . The book is full of detailed descriptions, numerous measurements and beautiful figures. However, what really got me excited was, in their description and comparative anatomy of P. atrox , Merriam and Stock (1932) provide identification criteria for the Lion and Tiger, a translation of the one devised by the French palaeontologist Marcelin Boule in 1906. I have forever been looking for a set of rules for identifying lions and tigers and ultimately had to come up with a set of my own with a lot of help...

Spinosaurus, the gigantic pangolin of the Cretaceous?

I was made aware of this not long ago - it kind of looks creepy, but it gave me an idea: Did Spinosaurus walk like a pangolin? That is, with it's hands low to the ground but not touching the ground - so no knuckle walking - and maintaining balance as a biped... This pangolin seems to maintain balance on its hind legs even though, on cursory glance, its centre of mass seems too far forward for that. Spinosaurus is supposed to have had a dense femur, so maybe its centre of gravity was farther back than you'd think from overall proportions. Maybe the sail helped tip the scale back? ...or maybe it was a giant ant-eater? Those giant claws look particularly suited to breaking open termite mounds? Who knows. This is me being silly, but thought it was hilarious enough to share...

Top 10 scientifically important theropod dinosaurs of all time (off the top of my head)

I thought I'd do a fun post for once. And since list based articles are the norm for fun on the internet, I thought I'd do one on dinosaurs, but given that I know most about theropods, I've decided to restrict my list to theropods (...maybe in a future post, I'll do other clades). My ranking is based mostly on scientific importance so it may not reflect awesomeness, and it is obviously subjective as to how I rank importance to science. For instance, interesting discoveries or unique palaeobiology are ranked relatively low compared to wealth of information and data or completely revolutionising our understanding of the evolution of theropods. So here are my top 10 scientifically important theropod dinosaurs of all time (off the top of my head) 10. Megalosaurus Being the first dinosaur to be named, Megalosaurus automatically deserves a spot on this list, but given the fragmentary nature of known fossil specimens, and being mostly useless as a meaningful source ...
