Abstract
Macro-scale rangeomorph fossils, with characteristic branching fronds, appear (571 Ma) after the Gaskiers glaciation (580 Ma). However, biological mechanisms of size growth, and potential connections to ocean geochemistry, were untested. Using micro-CT and photographic measurements, alongside mathematical and computer models, we demonstrate that growth of rangeomorph branch internodes declined as their relative surface area decreased. This suggests that frond size and shape were directly responsive to nutrient uptake.
