Polypora Bryozoan Fossil


Bryozoan fossils are pretty common but in general they are found in fragments or just large mats on limestone matrix. This fossil find is quite nice in that this bryozoan has part of its holdfast and three-dimensional matrix where the little bryozoa lived. It appears to be a Polypora shumardi. The fossil was found the in Beechwood Limestone of Clark County, Indiana USA. These little creatures lived during the Devonian Period.

My cousin Kenny provided this image and was able to extract it out more by using a slow drip acid preparation technique.

PaleoFauna Coloring Book - Kickstarter Project



I believe in supporting new ideas and products using Kickstarter. So far I have supported 3 technology projects and like to visit the site to see what new projects are being launched.

I came across the Coloring Book of PaleoFauna by Diane Ramic of Bowling Green, Kentucky, USA. This looks like a neat idea and ambitious with 200 pages. The author has already 5 books published including one on dinosaurs.

If you get a chance check out this campaign and support if you want a neat coloring book of creatures that only exist as fossils now. The campaign ends on August 6, 2017.

Gertie the Dinosaur Videos


I came across of video on YouTube of what is called the first animation featuring a dinosaur. It is a short animation from 1914 by Winsor McCay. Gertie was based off an Apatosaurus dinosaur fossil skeleton (known at the time as Brontosaurus). There is also a mammoth for comic effect later in the film. An odd appearance of a winged dragon flying across the screen shows up as well. This Wikipedia article about this film explains that the animator was not sure of the mechanics of the dinosaur standing up was so the flying lizard was added to draw the viewer's attention away during this event.

The film introduced a number of animation techniques like keyframing, tracing paper, registration marks and looping frames to show movement. The film is part of the U.S. National Film Registry. The film below is just the excerpt of the animation from the 1914 original, it lasts about 5 minutes.




This next video shows one of Winsor McCay's last animations showing how Gertie evolved in animation terms from 1921. It was from a never finished short entitled "Gertie on Tour".


Below is a embedded video link to the full movie short from 1914 that is about 14 minutes long. It features a side story about visiting the American Museum of Natural History and a bet to make one of the dinosaurs move.

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.
