Dinosaur in a Cliff II

After two weeks of sawing and jackhammering, the team has cleared the sandstone ledge from above the quarry face.  This is always the moment when the real excitement begins… what’s actually buried here?  Something amazing?  Just a few ribs or frags?  Our first exposed elements consist of a limb bone and several ribs.  The best parts are the patches of skin impressions scattered here and there among the bones.

Exposed skin impressions were one of the reasons we went after the specimen, despite the cliff.  Where there’s skin, there’s usually good preservation, and good preservation means there’s likely to be good scientific data.  Much remains to be learned about skin preservation in the fossil record, which is a line of research being pursued by several NCSU graduate students.  From a taxonomists perspective, the dinosaurs of this age and region are important.  Most of them no doubt represent new species.

As the summer excavations draw to a close, we hope to learn more about which bones were recovered.  The fruits of this summer will be prepared in the CNCC lab over the coming year.  We’ll keep you posted on the research.  In the meantime, the team is happy to be done with the jackhammer until next time!
