big teeth of theropod

[THammann@t-online.de (T Hammann)]

Hi all,

if you've seen the picture on Fred's page: 
http://www.dinodata.net/germanyuk.htm 
what do you think of the skull so far? As I wrote to you earlier I'm no 
paleontologist at all so my following questions might sound a little bit naive 
for an expert:

VIOHL said that this animal was not fully grown up and that it probably could 
reach a length of 2 metres and more. Does that mean that its teeth would grow 
in 
the same proportions? A fully grown up dinosaur with such big teeth would have 
looked a little bit grotesque. And which animals of this region (I always 
thought that there were only small island in that region in the Jurrassic) 
could 
be the potential prey of an adult specimen? Even VIOHL couldn't answer this 
question so far.

Thanks for any information,

Greetings,
Thomas
