I recently got started sculpting digitally, and with this new hammer I am now excitedly looking for nails! My thoughts turned to some of my microfossils, specifically some of my really old shark teeth. Microfossils in general are difficult to appreciate without a microscope, so I figured it would be fun to sculpt a few. My first subject is a Devonian Phoebodont shark tooth that I thought looked neat enough. Besides being some of the oldest teeth I know of (380-390 Ma), they look very different from the teeth of modern sharks (except for those of the frilled shark).

These shark teeth are very brittle and fragile - finding a complete one seems very unlikely. From the Genundewa Limestone.-

A Phoebodont shark tooth dwarfed by the head of a pin - they are very tiny and difficult to manipulate. From the Genundewa Limestone.-

Most teeth are fragmentary, with the Phoebodus-type teeth being the most common. -

One of the most complete teeth of this kind I've found so far (intact root, just missing two of the cusps). It's remarkably similar to Orhacanth shark teeth from the Permian, being tri-cuspid with the little "button." -

Yes, sharks used to have spines! Xenacanth sharks in the Permian and Hybodont sharks did as well. This is the only shark spine I've seen from the Devonian - if you've got one, would love to see it. -
