This is a piece of dinosaur bone I purchased a while ago when I was going a bit crazy with seeking out interesting patterns for my Stonescapes series of images. I was attracted to the unique pattern and colors, something I was completely unaware could happen with dinosaur bones.

As it turns out, as I understand it in a no-way-close-to-a-paleontologist-paleobiologist kind of way, the fossilization process with dinosaur bones is very much like the fossilization process with petrified wood (which I am also a big fan of.) The softer parts decay and the harder structural elements (I am guessing calcium?) remain to maintain the patterns. If exposed to the right minerals dissolved in water, the soft cavities get replaced with these minerals as water fills the spaces and ultimately evaporates. The colors come from the trace minerals that were present – and given the red, perhaps more than a bit of iron/hematite, the same source of the red color in the Marra Mamba stone I posted about earlier.

Prehistoric Planet

Coincidentally, I just started watching the new series Prehistoric Planet on Apple TV+ which is nothing short of AMAZING. It is narrated, appropriately, by David Attenborough. Already in the first episode, it has shown itself to be a brilliant piece of natural history filmmaking and digital technology. I will be quite disappointed if it doesn’t win quite a few awards for the realism it brings to exploring this fascinating period of our planet.

Science and Learning Influenced Art

I first approached this piece of dinosaur bone from a visual aesthetic perspective. It was the color and pattern that first caught my eye when I first came across it as I was largely unaware of the details of its formation. The labeling as dinosaur bone certainly added to the intrigue. But that initial attraction and curiosity prompted me to want to learn more in detail about the natural history involved in the creation of such fascinating things.

This approach fuels a lot of the photographs I’ve made. Quite often when out in the woods, even during my time underwater, I’ll have no clue as to what something is, but it is interesting to me visually. So I’ll make an image of it and later spend time learning more about it. It is widely recognized that you can become better at photography by being a better naturalist. Sometimes the opposite can be true also. You can learn more about nature, even dinosaurs, by simply following your eye. And already I am learning much more about dinosaurs simply because of the visual attraction to a natural history program made possible through technology.

Between Worlds

Between Worlds

In May, I spent some time in an expansive dunescape on Michigan's western shore. Silver Lake Dunes is an exciting place near the small town of Mears, Michigan. "Expansive" is quite a relative term, though. If you look for it on a map of Michigan, it is just this tiny...

On Delusion of the Senses

This is another aerial photograph, a nadir view, of the Silver Lake dunes in Michigan, taken at about 200 ft (61m) AGL. I admit I didn't see the shape of a human head when I first saw it from the air, but there was certainly enough intrigue about these patterns in the...

Royal Sahara Jasper

While doing some image organization in Lightroom, I came across a batch of photographs I had previously published to my site but somehow got "lost in the shuffle" when I migrated all of my image galleries many years ago. They've been omitted from my Stonescapes series...

    I am amazed with the trailer. And, I also thank you again for teaching me more about nature, history and photography. I also am captivated by your image and would also be captivated holding the dinosaur bone in my hand.

      We are only partly through episode 2 and it sure is impressive, sometimes you forget you are watching something not filmed in the wild.

      Thanks for the kind words Monte. If I can share what I learn, I guess it then makes it count double! 🙂

    Neat photo! It is mind-boggling when you think of how old it is and what the planet might have looked like when the bone was actually in the dinosaur!

    • Mark

      Indeed it is – I wouldn’t have a clue as how old exactly this piece is, but my understanding is that most dino bone samples are from the Jurassic Period – so – really old. 🙂

    Thanks for the tip on Prehistoric Planet, I’ll be sure to tune in! (well, we really don’t ‘tune in’ anymore do we). I’ll be streaming in tonight!

      I suppose we “click in” now? I’ll probably be watching more tonight also.
