It's complicated.  :-)

I follow Rauhut in recognizing that _Altispinax_ is the valid name for the 
tall-spined Wealden theropod from England.  Rauhut's rationale is that Huene 
explicitly proposed the name _Altispinax_ for the distinctive vertebrae, not 
for the indeterminate tooth that was originally named _Megalosaurus 
dunkeri_.  I'm sure some people would disagree with this interpretation 
(e.g., the guy who proposed the name _Becklespinax_).
