  Yes, and I noted a week or so ago that beyond a limited range in southern 
Germany, Archie is otherwise unknown. This suggests it was limited in extent, 
and possibly in ability to extend its range. The range may be analogous to the 
range of the solitaires and dodos in the near-Madagascan islands of the Indian 
Ocean, which arrived there when flighted, then lost the ability fairly rapidly. 
It may also be the largest non-fully terrestrial carnivore in the Solnhofen 
limestone, given that crocs were confined to the water for the most part, 
*Compsognathus*/*Juravenator* were probably the arch terrestrial predator, but 
that may not leave much more to its habitat. I don't think its diet is even 
fairly grounded at this point.

  Recurved, compressed, small, relatively even teeth imply some possible 
insectivory, and I am sure the teeth of *Compsognathus* imply more 
flesh-processing capability.
