Yes, it probably should be. I intended it to show, for example, everything between Allosaurus and Mapusaurus as being progressively more derived. Ths is really how it should have been:Am I to assume your cladogram should be indented? So it would actually be like this?
|--Ornithischia `--+--Sauropodomorpha ...`--+--Guaibasaurus ......`--+--Eoraptor .........`--+--+--Herrerasaurus ............|..`--Staurikosaurus ............`--+--Segisaurus etc.
Dubreuillosaurus is very similar to Afrovenator (Holtz et al., 2004).
Shuvosaurus is a crurotarsan, as shown by the discovery of Effigia (Nesbitt and Norell, 2005).
Nope, no lacrimal is known for Piatnitzkysaurus.
I guess that leaves only the frontal then...
Tykoski (2005) found Liliensternus and Zupaysaurus to share the following characters with other coelophysids- alveolar ridge on maxilla; deep ventral fossa on ectopterygoid; low post-axial cervical neural spines; ischiopubic ratio <66%; proximal end of metatarsal III with ventral boss; anterior ramus of maxilla <10% maxillary length; more than 19 maxillary teeth; anterior margin of antorbital fossa squared; anterior lacrimal process longer than ventral process; cervical ribs fused to vertebrae in adults.Some of those could be primitive characters that were later lost. Are any of these known for Eoraptor or the herrerasaurids?
What characters do Ceratosaurus and abelisaurs share that Spinostropheus doesn't?You're right. I honestly should have checked more carefully. Spinostropheus probably is closer to the abelisaurs.
I look forward to seeing your coelurosaur cladogram.I'll have it up this afternoon.
