Geology & Paleontology of the Kem Kem Group


Recommended Posts

Excellent paper that examines the geology and paleontology of what they call the Kem Kem Group that includes the lower Gara Sbaa and upper Douira formations .  I will add that the authors view of the dinosaur assemblage in this fauna does not agree with recent publications from other paleontologists.   Great images of croc teeth, dinosaur teeth and claws.

 

It even discusses  "that some geographic names are simple errors that gain traction in secondary citations. In  a  prominent  compilation  of  dinosaur  localities,  for  example,  the  term  “Tegana  Formation” was cited for the “Kem Kem beds” (Weishampel et al. 1990). This may have arisen as a misspelling of the “Tegama Group”, a name for Cretaceous age beds in Niger. Although the error was noted (Sereno et al. 1996), it has reappeared in subsequent publications (e.g., Bailey 1997, Kellner and Mader 1997,  Taverne and Masey 1999, Weishampel et al. 2004)"

Still browsing through it. There's a lot of good reference material in here.

 

Also finally some Deltadromeus photos that aren't paywalled.

so whats the deal with sigilmassasaurus now then?

No change, like I said the authors here have a very different view than most other paleontologists.  Hey what else is new when you have so little to go on.  With new discoveries everything will become clear :heartylaugh:

Seems like both Sigilmassasaurus and Sauroniops are being lumped into Spinosaurus and Carcharodontosaurus respectively.

Impressive paper, but for me as a scientific noob I have to ask the one question:

 

For our everyday teeth ID regarding teeth from KemKem, do we have anything new that helps us?

NO nothing has changed regarding teeth.  We basically cannot identify any theropod teeth to a genus/species only to a family level.
