Sauroniops is not Carcharodontosaurus

[Troodon]

Along with the debate on how many Spinosaurids are there in the Kem Kem we have a similar one on Carcharodontosaurids.   Attached find paleontologist Andrea Cau blog on this subject.  He analyzes the arguments brought by Ibrahim et al. (2020) and offers his rebuttal:

His Conclusions 

 

"1) The front of Sauroniops is not 60% of that of Carcharodontosaurus , but of comparable size (and proportionately more stocky and broad, and both extend over 19 cm above the skull).

2) The position of the prefrontal facet of Sauroniops is not homologous to that of Carcharodontosaurus (anteromedial in the first, posterolateral in the second).

3) Sauroniops does not present diagnostic characters of Carcharodontosaurus at the level of the temporal fossa and the interorbital septum.

4) Carcharodontosaurus does not show the diagnostic character of the expanded dome at the level of the preorbital area, nor the deep separation of the nasal branches, diagnostic of Sauroniops .

 

Therefore, there is no reason to consider the two taxa as synonyms ( contra Ibrahim et al. 2020)."

 

 

 

Hopefully we will see something similar on Sigilmassasaurus from the authors with papers on this genus.
