Quantitative comparison of geological data and model simulations constrains early Cambrian geography and climate
Marine ecosystems with a diverse range of animal groups became established during the early Cambrian (~541 to~509 Ma). However, Earth's environmental parameters and palaeogeography in this interval of major macro-evolutionary change remain poorly constrained. Here, we test contrasting hypothese...

Marine ecosystems with a diverse range of animal groups became established during the early Cambrian (~541 to~509 Ma).
