Abstract






Aim



Poleward migration is a clear response of marine organisms to current global warming
but the generality and geographical uniformity of this response are unclear. Marine
fossils are expected to record the range shift responses of taxa and ecosystems to
past climate change. However, unequal sampling (natural and human) in time and space
biases the fossil record, restricting previous studies of ancient migrations to individual
taxa and events. We expect that temporal changes in the latitudinal distribution of
surviving taxa will reveal range shifts to trace global climate change.







Location



Global.







Time period



Post‐Cambrian Phanerozoic aeon.







Major taxa studied



Well‐fossilized marine benthic invertebrates comprising stony corals, bivalves, gastropods,
brachiopods, trilobites and calcifying sponges.







Methods



We track deviations in the latitudinal distribution of range centres of age boundary
crossing taxa from the expected distribution, and compare responses across latitudes.
We build deviation time series, spanning hundreds of million years, from fossil occurrences
and test correlations with seawater temperature estimates derived from stable oxygen
isotopes of fossils.







Results



Seawater temperature and latitudinal deviations from sampling are positively correlated
over the post‐Cambrian Phanerozoic. Simulations suggest that sampling patterns are
highly unlikely to drive this putative signal of range shifts. Systematically accounting
for known sampling issues strengthens this correlation, so that climate is capable
of explaining nearly a third of the variance in ancient latitudinal range shifts.
The relationship is stronger in low latitude taxa than higher latitude taxa, and in
warm ages than cool ages.







Main conclusions



Latitudinal range shifts occurred in concert with climate change throughout the post‐Cambrian
Phanerozoic. Low latitude taxa show the clearest climate‐migration signal through
time, corroborating predictions of their shift in a warming future.
