I’m Sam Penrice, I recently completed my PhD at the University of Lincoln.


My current research is on the evolution of form and function, over long periods of time. To do this, I use stereospondyls as a model. No, it isn’t a strange kind of speaker from radioshack, Stereospondyls are ancient amphibians. They are some of the most well known early tetrapods, at my last count there were 262 described species, from every continent. Have a look at my other pages if you want to find out more. I’ve got a lovely collection of nearly 20,000 photographs of these super-giant-newt-monsters.

I can’t put my research experience in to a single box. In my past lives I’ve done a lot of different things, both academic and not. I used to lecture in Equine Science, I researched physiology and psychology (not the same project). I have even written a book chapter on the bite mechanics of dog jaws. Before this I was an assistant trainer and business manager at a start up ranch in Texas, and I’ve been lucky enough to explore a lot of the world.

Teaching is important to me, I always want to share what I know, in lots of different formats, with lots of different people.


On this site you will find everything from my research highlights to tutorials and photographs.
