GIRI (Griding, Imaging and Reconstruction Instrument)

The digital fossil project we are working on with Adam Maloof now has a name – GIRI (Griding, Imaging and Reconstruction Instrument)

We’ve been testing out a few medium format digital back cameras and macro lenses for GIRI. These cameras provide the highest resolution imaging you can achieve before moving to microscopes. Check out what our Limestone specimens look like at 80 megapixels….Holy Cow!

 Each of the holes shown in this image are 1mm in diameter.

Newly published evolution textbook features Maloof/Situ Studio research

The Trezona Fossil research that Situ Studio conducted with Professor Adam Maloof is featured in Carl Zimmer and Douglas Elmen’s textbook titled “Evolution: Making sense of Life.”  The work appears in the chapter titled: What Rocks Say: How Geology and Paleontology Reveal the History of Life. Very exciting to see this research codified into the foundational texts for evolutionary biology!

The textbook is designed for university level biology majors.

The top of the page is an image from the Trezona fossil reconstruction we worked on with Adam.

Fossil Lab at Princeton


Construction has begun on the digital fossil reconstruction lab we are working on with Adam Maloof, professor in the department of Geosciences at Princeton University. Situ and Adam are currently building an instrument that will become the centerpiece of the lab: an automated serial grinder/imager. The project is funded by the National Science Foundation and will be complete in January. We will be posting more images and fossil lab updates in the coming months, but in the meantime, check out the TEDxCooperUnion talk, where we spoke with Adam about the project.

Digital-Fossil-Reconstruction Software Tests


We’ve been making progress on the Digital-Fossil-Reconstruction project that we are working on for Adam Maloof’s new lab at Princeton University. Most recently we purchased the surface grinder that will serve as the center piece of the lab and will begin working on the hardware retrofit in the coming weeks. While we wait for the grinder to arrive we’re experimenting with some pretty incredible software that allows us to convert stacks of photographs into a 3d digital model by converting each successive image’s pixels into 3d voxels. This software, called Avizo Fire, is mostly used for applications in x-ray computed tomography but we are appropriating it for optical imagery reconstuction. Check out the video below, a test we ran on some of the images we had of the Trezona rock samples….pretty amazing tool!
