Multi-scale Investigation of Early Animals Using Advanced Synchrotron Approaches

Project description

Understanding how early animal fossils reveal Earth’s evolution

The emergence of animal life at the end of the Proterozoic Eon and the start of the Phanerozoic Eon, during the Ediacaran and Cambrian periods, marked a key moment in Earth’s history, characterised by tubular fossils and the rise of bilaterian animals. However, studies on their morphology and chemical composition are often limited. Supported by the Marie Skłodowska-Curie Actions programme, the MINERVA project will assess how fossils of early animals relate to the animal tree of life and their impact on Earth’s evolution, focusing on biomineralisation and substrate utilisation in biogeochemical cycles. Using advanced microtomographic techniques, the project will explore the early evolution of animals through a combination of synchrotron and lab-based analyses.

Objective

The onset and fast diversification of animal life is arguably the most important biotic event in the history of life on Earth, taking place at the end of the Proterozoic and beginning of the Phanerozoic Eons, encompassing the Ediacaran and Cambrian periods. During the latest Ediacaran, a widespread biota of tubular fossils and trace fossils (e.g. burrows in the sediment) not only marks the debut of bilaterian animals, but also of biomineralization processes mediated by animals. The advent of biomineralization forever changed the ecological landscape at the dawn of animal life, influencing ecological interactions, colonization patterns, and consequently the evolution of the first reefs. Tubular animals continued to be among the most common components of Cambrian rocks, while trace fossils show a dramatic increase in the complexity of animal behaviors. Despite the importance of this biota, only few studies dealt with combined aspects of their original three-dimensional morphology and chemical composition, and even then, mostly using lab-based methods that might not provide the necessary resolution to understand the ultrastructure of these fossils at the micro and nanoscale. Evaluating how these fossils and vestiges of early animals are related to the animal tree of life and how they impacted the evolution of Earth (e.g. biomineralization and substrate utilization as key factor in biogeochemical cycles) is the endeavor of MINERVA. With novel and advanced microtomographic approaches at its core, this project will tackle the early evolution of animals through a pioneering combination of advanced synchrotron and lab-based complementary analysis.
