\uc1\pard\plain\deftab360 \f0\fs20\cf0 For those who asked it, French being my language, I will try to translate a few of the points common both to *S. altdorensis* and *E. oxionensis* ( forgive my poor knowledge of scientific words )\par
- in both genera, the ventral surface of the centrum of the first dorsal vertabrae bears two distinct hypapopyses anteriorly separated from each other. This character is said to be unique among theropods.\par
- the presence of a ventral careen on the centrum of dorsal vertebrae seems to be a synapomorphy of tetanurae ( Rauhut 2000 ). This character is thus found in all Allosauroidea and some Spinosauridea such as *Torvosaurus* and *Baryonyx*. This ventral careen is absent only in 2 tetanurae, *S.* and *Eus.*\par
- in most theropods, the length of the centrum of the posterior dorsal vertebrae is less than or equal to the height. In the Coelophysoidea and the 2 genera discussed, the centrum is significantly longer than high ( Rauhut 2000 ).\par
- the pubis morphology is similar to that of the Spinosauroidea and the distal end is poorly developped posteriorly and even less anteriorly in both genera as well as in *Afrovenator*, *Baryonyx* and *Torvosaurus*.\par

Hope this helps,\par

Haven't seen this mentioned on the list yet:\par
Allain, Ronan. 2001. Redescription de _Streptospondylus altdorfensis_, le\par
dinosaure theropode de Cuvier, du Jurassique de\par
Normadie. Geodiversitas. 23(3):349-367.\par
\par
Redescribes _S. altdorfensis_, and finds it to be a valid, diagnosable\par
taxon (I can't read French, so I don't know what features support\par
this.) All large theropod remains from the Callovo-Oxfordian of the Vaches\par
Noires are referred to this taxon, inlcuding the \par
following: Streptospondylus rostro-major sensu Owen, \par
1842; Streptospondylus cuvieri Owen, 1842 (Megalosaurus cuvieri); Laelaps\par
gallicus Cope,1867; Eustreptospondylus divesensis Walker, 1964\par
partim; and "crocodile fossils" Cope, 1800;1824. Some vertebral features\par
link _Streptospondylus_ with _Eustreptospondylus_, and both taxa are\par
assigned to the Spinosauroidea.\par
