There is an interesting new trend in using Computational Fluid Dynamics (CFD). Until recently CFD simulation was focused on existing and future things, think flying cars. Now we see CFD being applied to simulate fluid flow in the distant past, think fossils.

CFD shows Ediacaran dinner party featured plenty to eat and adequate sanitation

Add to this new trend of analyzing the past with CFD, the flow around Ediacara biota from fossils found in Bethanien, Namibia. Researchers at Vanderbilt University used CFD to explore the ecosystem supporting Ediacara biota or, to be more precise, "Gregarious suspension feeding in a modular Ediacaran organism."
