Unusual find of putative Placoderm Fossil at Penn Dixie


Recommended Posts

Biotalker

At the “Dig with the Experts” earlier this month at Penn Dixie, I found this interesting surface fossil on a block that the on location experts seemed to agree was a placoderm fossil. Approximately 5 inches (12.5cm), it is thin, pigmented and has intermittent perforations or pustules. In an adjacent pile, another more extensive and remarkable set of fossil strips like this presumptive placoderm were found by another rock buster. Anecdotally, it was remarked by staff that these two putative placoderm blocks were excavated from the “same region” of the pit as the apparent Dunkleosteus jaw discovery.

 

 

 

Perhaps just a coincidence, but nonetheless an interesting mystery.

Not sure the place itself is getting better, (It has always produced great finds!)  or that people just are recognizing the fossils better.  ;)

A friend of mine was there last week. They are actually digging a bit lower than the classic trilobite layer now, but they may need to dig a relief trench for drainage as it is now well below the water line. The deeper cut is likely resulting in some more placo finds now.
