Stromatolites are a trace fossil of the biofilms of blue green algae that grow around an object such as shell of an oyster or other mollusc. As the algal filaments grow outwards, sediment is continually deposited and accreted onto the surface of the algae, thus increases in size forming the distinctive concentric rings that you see when the fossil is broken in cross section. They form knobbles round boulders and can reach sizes of a meter wide in the fossil record. Stromatolites grow in shallow, hypersaline pools in shore settings, inhospitable to molluscs which might otherwise graze on the algae. Modern day examples of marine stromatolites can be found in Shark Bay in Australia.

MAY 2020

You may have noticed that some of our 3D digital models are currently unavailable for web viewing. We are working to transition these models to a new visualization tool and appreciate your patience. Contact us at africanfossils@turkanabasin.org if you have any questions.

OUR MISSION

African Fossils seeks to increase public knowledge about prehistory by harnessing modern technology. Through digitizing otherwise inaccessible discoveries, African Fossils is dedicated to creating a growing repository of 3D models of significant fossils and artifacts, thus making them freely accessible to all. By allowing members to share their 3D printed creations, we hope to aid teachers, students and enthusiasts to exchange ideas and to be inspired to think about our tenuous place on the planet.

OUR METHODS

Most of the models have been captured using photometry and an SLR camera mounted on a tripod. The software used to convert the photos into 3D digital models are: Autodesk®123D™ Catch, Autodesk® ReCap™ Photo and the point clouds are processed using Autodesk® ReCap™ Photo and Meshlab. Many of the models were captured using the Artec range of Structured Light Scanners, Artec Spider, Artec Eva and Artec Space Spider in conjunction with the software Artec Studio. In addition some of models were captured using the LMI Technologies structured light scanner. The scanned collections include specimens housed in the National Museums of Kenya and the Turkana Basin Institute field stations. Some scans are taken from cast replicas rather than original specimens. The digital models on this site have been made available under the Creative Commons Attribution-Non Commercial-Share Alike License.
