IIRC, _Altispinax dunkleri_ is just teeth; _Becklespinax altispinax_

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_).
