Last year our best discovery came in a little package—Fortunate Son, the site of a new species of dinosaur. When a new dinosaur locality is found, our permits allow us to explore the extent of the bone preserved at the site over only a small area—about one square meter. We collect what we can from the surface and try to figure out just how much of the skeleton may be preserved and over how big an area. But the truth is, there is no real way to know until you cut a quarry into the hill. Luckily for us the bones of Fortunate Son were densely packed in the hillside and we collected over thirty bones from that single meter area under our surface collecting permit last year.
A year later, armed with an excavation permit, we are finally able to put our wonderings to rest. Yesterday, three of us we spent the day picking and shoveling out a quarry face at Fortunate Son. This involves quickly removing all the overburden (rock layers that overly the bone layer), so we can get closer to the bones before we break into fine tools. It is a bit unfortunate that a large sandstone boulder is resting atop the main bone-bearing horizon at this site. We will likely need to find a way to move that boulder, and soon.
At any rate, now the fine work can begin here. It may be that very little bone is preserved at Fortunate Son and all that work was for naught. It may be that treasures await just under the quarry face we carved out yesterday. Only time, patience, and chisels will tell.
