Perfect Pteranodon Bones!

Recommended Posts

I've been heavily hunting numerous localities in both Gove and Logan counties. Here is one of those hunts:

April 4th Fossil Hunt

I was finally able (after several years) to gain landowner permission to hunt an exposure of upper Smoky Hill Chalk. The fauna and aspects of preservation are significantly different that those of the lower chalk. After a few hours I came across the familiar light-blueish bones that could only be those of a Pteranodon.

I began to follow the bone back into the rock. Pteranodon bone is some of the most fragile and thin bone to be found in this formation. I tried to keep as much of the bone buried as possible (while trying to discern the extent). This was so the delicate work close to the bone could be done in the lab not in the field with a hammer.

At this point I was unsure wether I wanted to take the specimen out in one block or in a plaster jacket. The chalk seemed reasonably stable. Then, near disaster! Thinking I was a sufficient distance from the main piece I suddenly struck another bone. This was totally unexpected as I thought I was only dealing with a single metacarpal. Luckily, I only grazed the tiniest of fragments from the piece.

Here is the extent of the discovery showing the unexpected bone (on the right side). I later learned this was the scapulocoracoid, which is in the shoulder area (basically where the wing attaches).

Once in the prep lab I took extra care with the bones as they were some of the best quality I've ever seen. After some time, I also found out that the pteroid bone was present! This was exciting for me as this is a rather rare bone. I'll show a diagram here in bit.

Very cool. Definitely not something you see everyday. I'm doing the landowner dance myself right now... Congrats!

If you show them a transitional, they'll ask for two more. ;)

During the prep, I made the decision to remove the scapulocoracoid:

Those fragments to the left are those that had fallen down hill and the pieces in weak surface chalk.

Here is the final product of hours of prep and preservation:

Those are really super finds and excellent prep. Congrats!.

Flying critters of all kinds are fascinating. Back in Sept Dr. Brian Andres talked about pterosaurs of all kinds at the Tampa Bay Fossil club mtg and it was wild to hear about the variety....

Continued hunting success!

Regards, Chris
