Other dinos in the quarry are _Iliosuchus incognitus_ and indeterminate
hypsilophodont-grade ornithopod.
A tyrannosauroid?

As the existence of _Megalosaurus_ as a valid group (of bones) is
questionable, I think you can see why the next step up is even more
tentative. I have a contribution forthcoming that does support a
grouping f _Meg._, _Torvo._, _Poekilo._, _Eustrep._, _Piatnitzky._,
_Afrovenator_, and someone else (heh, heh, heh...), to the exclusion of all
other theropods. One the other hand, if you do NOT consider the
non-dentary _M. bucklandi_ material as belonging to a single taxon, the
monophyly of Megalosauridae falls apart relative to other basal
tetanurines. As for what supports it: wait for the paper... :-)
Will do.

See above.
Whoops, I mean to ask if they should be sunk into Megalosaurus.
