Spiny Brachiopod Fossils

I would not call this fossil rare while at the same time not say it is common either. What makes this particular find nice is the number of preserved spines. The brachiopod has to be found in matrix as to protect those spines from breaking away from the shell.  These brachiopods appear to be a Productella spinulicosta (Hall, 1867). It was found in the Jeffersonville Limestone of Clark County, Indiana USA. Fossils date to the Devonian Period.

Thanks to Kenny for showing me this fossil.

Megalodon 3D Printed Tooth Fossil

I have been printing some more Megalodon shark tooth fossils based off the scanned model found here: http://www.thingiverse.com/thing:1380493

These images show my latest variation where I printed the layers are 0.1 mm so the tooth consists of over 900 layers. I also added a base made with OpenSCAD as well raft printing to make the base more stable. I tried to slow the printing down so the bottom of the tooth is less stringy. It turned out better but still far from perfect. The print took about 6 hours.

Antholites Coral Fossil on Crinoid Stem

These images are of what appears to be an Antholites speciosus? coral growing on an unidentified crinoid stem. It was found in the Jeffersonville Limestone of Clark County Indiana USA. The fossils date to the Devonian Period. The specimen is about 3 cm long and 1 cm wide.

The book Silurian and Devonian Corals of the Falls of the Ohio (Stumm, 1964) was used to identify this specimen.  Description on page 79 and plate 73, figures 1-5.

Tentaculites richmonensis Fossils

Here is an image of a nice plate of fossils found in the Lexington Limestone of Franklin County, Kentucky USA. There are at least 8 Tentaculites richmonensis shown in the image around that brown object which is an Isotelus trilobites hypostome (feeding scoop). Also in the images are brachiopods and bryozoans.
