The paper presents an interesting review of deep time ecosystems and suggests that the interpretation of the evolution of ancient sedimentary systems can be refined and better compared to today’s changes in ecosystems. Concerning the rate of climate change, this study implies that anthropogenically induced global warming and subsequent sea level rise today occurs more than ten times faster than the fastest rise reconstructed for the Oxfordian (159 Ma - 154 Ma)

Some 155 million years ago, sediments were deposited in a shallow subtropical sea. Coral reefs formed in a warm and arid climate during high sea level, and clays were washed into the ocean at low sea level and when it rained. Climate and sea level changes were induced by cyclical insolation changes. Analysing the sedimentary record, it appears that sea level rise today (as a result of global warming) is more than 10 times faster than the fastest rise reconstructed from the geologic past.
