Triassic Osteoderm ID - Aetosaurs or Phytosaur?

Recommended Posts

GeschWhat

This osteoderm was in a box of Bull Canyon Formation (Triassic - Norian) coprolites that I have been going through for the past year. The fun thing is, I one of the coprolites in this batch appears to have osteoderm inclusions that look very similar. I have looked at well over a thousand coprolites from this formation, and this is the first time I have found inclusions such as these. Needless to say, I am super, super excited!!!! Best I can figure it is from an aetosaur or phytosaur, neither of which are familiar to me.

 

I did send an email to the person that found them to see if she is able to identify it, but thought I would throw it out to the forum at the same time. Any assistance you provide would be greatly appreciated.

 

@Carl check it out!

Chronosuchia,Rauisuchia,aetosaurs,phytosaurs....

The paramedian osteoderm from the Typothorax coccinarum (Figure 1C) in the first paper looks like a close match.

I would be. I don't know what I can tell from the coprolite inclusions since it might be fragmented, but based on the thickness of the osteoderm in the coprolite as compared to the fragment, I was thinking those in the coprolite might be from a juvenile.
