Fossil Hunting for Devonian fish at the Red Hill Fossil Site: April 2009
Red Hill is an interesting site. It contains remains of one of the Earth's earliest tetrapods,
one of the first true forests, and even one of the first forest fires. The main reason why many people come
to red hill is to find early Devonian fish. Namely lobe finned fish, placaderms, and primitive sharks. As stated
in all my trip reports pertaining to this site, the fossils are fragmentary in nature and very difficult to extract.
The DVPS led this trip. They came prepared with lots of heavy hammers, chisels, and shovels. The trick to this site is to create/clear off a shelf, and then to neatly split slabs off the shelf. Many of the DVPS crew are pros at doing this. Within minutes they will all be lined up clearing off a large shelf along a productive layer for extraction.
I, on the other hand, am not a pro. I spent most of my time looking for an area that could be turned into a shelf. Then I spent many futile attempts at trying to clear off a shelf. Finally when I cleared one off, it was the wrong layer. Needless to say, I did not get a large shelf cleared off where I could just pull up fossil laden slabs. By the end of the trip (when my arm was too sore to swing a sledge anymore) I had found a few Hyneria fish teeth, and some fragmented placaderm armor. On a sad note, one of the larger Hyneria teeth I found blew into dust in the wind before I could reach for glue to stabilize it. Al in all, I'm not disappointed, I have come to expect hardships from this site. However, it is such an interesting site, I will for sure return again to try my luck.
If you are interested the transition from fins to feet, and Tetrapod Evolution, I strongly suggest:
Gaining Ground, Second Edition: The Origin and Evolution of Tetrapods (Life of the Past)
by David R. Schwimmer, 2002
This book, full of comparative illustrations and photos, tells the story of tetrapod evolution, how it started 370 some million years ago, and goes through the different interpretations of the various early tetrapods. It is a must for anyone interested in Tetrapod evolution. If you have ever fossil collected at Red Hill, this book puts everything in perspective.
