Cheers jramauri, that link is definately useful and helped me think about searching for other reference material including generalised carnivore jaw muscles. The main reason I'm having a go this way is because I like the idea of learning about the inner workings while doing the modelling (crazy I know )

Hehe, yep Dave quite a bit of it is done on the train (the morning one doesnt bounce around too badly (40mins) but the evening one is a nightmare (1hr). Gonna try and get some done in the evenings this week so I dont get left behind by everybody else.
Looking forward to see another winner by yourself!

Thanks Pyrus, though I have a limited amount of head muscle information at present so it might end up being a bit of a guess job in some areas

More (minor) updates tonight
