So go and see them! Over the last year the University of Portsmouth (my uni) has been constructing life-size pterosaur models to go on display on London's South Bank as part of the Royal Society's Summer Exhibition. These models are huge! I've had the privilege of seeing one of them as a work in progress and they are a sight to behold. They have been modelled using up to date knowledge of pterosaurs and some of them are not in flying poses; they are the first to be shown standing and walking, of this size at least.
I sadly cannot embed the video, so follow this link, watch, and be amazed.
The image used is by Mark Witton, one of the palaeontologists who constructed the pterosaurs.
