Possible Discovery of Earliest Forms of Animal Life
Situ Studio has collaborated with Professor Adam Maloof of Princeton University’s Department of Geosciences on research that suggests the possible discovery of the earliest animal life on earth. Situ Studio has co-authored a paper with Professor Maloof and colleagues on this work in the September issue of the journal, Nature Geoscience.
Excerpt from Princeton University’s August 17 Press Release:
“Analyzing the fossils turned out to be easier said than done, as the composition and location of the fossils made it such that they could not be removed from the surrounding rock using conventional techniques, nor could they be imaged using X-ray scanning techniques. This is because X-rays are only able to distinguish between materials with different densities, which is why they can be used to image bones that are inside the human body or buried within a rock. But the most ancient skeletal fossils are made not of bone, but of calcite — the same material that makes up the rock matrix in which they are embedded. Therefore X-rays could not be used to “illuminate” the newly discovered fossils and the researchers had to develop and refine another method.
Maloof, Rose and their collaborators teamed up with professionals at Situ Studio, a Brooklyn-based design and digital fabrication studio, to create three-dimensional digital models of two individual fossils that were embedded in the surrounding rock. As part of the process, team members shaved off 50 microns of sample at a time — about half the width of a human hair — and photographed the polished rock surface each time. The team ground and imaged nearly 500 slices of the rock.
Using specialized software techniques developed specifically for this project, the researchers then “stacked” the outlines on top of one another to create a complete three-dimensional model of the creature. The technique is similar to the way in which CAT scan technology combines a series of two-dimensional X-rays to create a three-dimensional image of the inside of the body. The technique that was developed served to automate the process — turning a prohibitively time-consuming task into an efficient and effective method for fossil reconstruction.”
